Ventilator CPU -a ne radi jedna je od najčešćih pritužbi koje računalni tehničari dobivaju svakodnevno. Iako se problem čini jednostavnim, rješenje nije.

Na prijenosnom računalu CPU ventilator se inače napaja od 3V ili 5V, dok se na stolnom računalu napaja 12V iz jedinice napajanja ili PSU-a^{(Power Supply Unit or PSU)} . Zaglavlje ventilatora je priključak na matičnoj ploči gdje se ventilator spaja. Većina ventilatora ima tri žice/pinove. Jedan je za dovod napona (crveni), drugi je za neutralni (crni), a treći je za kontrolu brzine ventilatora^{(fan speed)} (zeleno)/(žuto). BIOS tada koristi stepenasti mehanizam za napajanje CPU ventilatora. Kako temperatura uređaja poraste iznad granične vrijednosti, ventilator se normalno uključuje. Brzina ventilatora raste kako temperatura i opterećenje  CPU -a rastu.^(CPU)

Zašto je hlađenje bitno?^{(Why is Cooling Essential?)}

Hlađenje^(Cooling) je neophodno kako bi vaš stroj najbolje funkcionirao bez pregrijavanja. To se postiže korištenjem ventilacijskih uređaja, rashladnih tekućina i, najčešće, ventilatora za hlađenje. Stoga^(Hence) je nedostatak ventilatora razlog za zabrinutost.

Za računalo, ventilator PSU , ventilator CPU -a, ventilator kućišta/šasije i ventilator GPU -a su svi primjeri ventilatora za hlađenje. Korisnici su izvijestili da kada se njihov ventilator CPU -a prestane okretati, stroj će se pregrijati i izazvati BSOD^(BSOD) . Zbog sustava za nadzor topline, stroj bi se ugasio. Možda se neće uključiti neko vrijeme jer bi mogao naići na pogrešku ventilatora tijekom procesa pokretanja. Ovaj će se članak baviti problemom i pokazati kako ga riješiti. Uključuje osnovna rješenja za scenarij 'ako vaš CPU ventilator ne radi'.

Koji su znakovi da provjerite ne vrti li se ventilator vašeg CPU-a?^{(What are the signs to check if your CPU fan is not spinning?)}

CPU ventilator postavljen na procesor trebao bi ga hladiti kako bi spriječio pregrijavanje i oštećenje. Kada prvi put uključite zaslon svog računala, možete čuti buku koju proizvodi. Kvar CPU^(CPU) ventilatora čest je problem koji utječe na sva stolna i prijenosna računala.

Ako se pojavi bilo koji/svi od sljedećih problema, uzrok bi mogao biti neispravan CPU ventilator:

• Računalo se često neočekivano gasi^{(The computer often shuts down unexpectedly)} – Ako se isključi i ne pokrene osim ako ne pritisnete gumb za uključivanje^(Power) da biste ga ponovno pokrenuli, možda je problem s ventilatorom.
• Računalo se više ne može pokrenuti^{(The computer can no longer boot)} – Ako se vaše računalo ne pokrene, možda ventilator CPU -a ne radi. To može oštetiti matičnu ploču.
• Logotip pokretanja se ne pojavljuje^{(The boot logo does not appear)} – Kada uključite zaslon, a logo za pokretanje se ne pojavi, moguće je da nema zvuka iz ventilatora CPU -a.^(CPU)
• Računalo je pregrijano^{(The computer is overheated)} – Kad vaše računalo radi neko vrijeme, dosegne visoku temperaturu i ventilator bi se trebao uključiti. Ako ne možete čuti kako se ventilator vrti, neispravan je.
• Ventilator CPU-a se ne uključuje^{(The CPU fan does not turn on)} – Kada uključite uređaj, ventilator CPU -a se ne uključuje.

Možete instalirati alat za pregled računala kako biste provjerili rade li hardver i softver računala ispravno ili ne. Aplikacija će vas obavijestiti ako ustanovi da ventilator CPU -a ne radi.

Koje su opasnosti ako se ventilator CPU-a ne vrti?^{(What are the Dangers if your CPU Fan is not spinning?)}

Kada ventilator CPU -a prestane raditi, to može uzrokovati mnoge probleme, kao što su:

1. Računalo se često neočekivano isključuje^{(The computer often shuts down unexpectedly)} – Računalo se često gasi bez upozorenja, što rezultira kvarom uređaja ili gubitkom podataka.

Na primjer, ako se vaš stroj neočekivano pokvari, nećete imati priliku spremiti svoje podatke. Također, kada ponovno pokrenete računalo, svi će vaši podaci biti izgubljeni.

2. Ventilator CPU-a prestaje raditi^{(The CPU fan stops working)} – Ako se to dogodi, može uzrokovati oštećenje CPU - a kao i matične ploče, zbog čega se stroj ne može pokrenuti.

Također pročitajte: ^{(Also Read:)} Kako popraviti računalo se automatski isključuje^{(How to Fix Computer turns off automatically)}

Koji su razlozi ako se moj ventilator CPU-a ne vrti?^{(What are the Reasons if my CPU fan is not Spinning?)}

To se može dogoditi zbog niza čimbenika koji su navedeni u nastavku:

1. Problemi s BIOS-om^{(BIOS issues)}

Do sada su ATX matične ploče imale mogućnost praćenja temperature i brzine CPU ventilatora u postavkama BIOS- a. ^(BIOS)Stoga nema potrebe fizički otvarati kućište uređaja kako biste provjerili CPU ventilator. Umjesto toga, dok dižete svoj uređaj, možete unijeti postavke BIOS- a da biste to učinili.

Ponekad BIOS možda neće moći pratiti brzinu i temperaturu procesora^(CPU) , što vas navodi da vjerujete da je ventilator CPU -a prestao raditi.

Ovaj problem je najvjerojatnije uzrokovan

a. Kabel za napajanje CPU ventilatora nije ispravno priključen:^{(The CPU fan’s power cord is incorrectly attached:)}  Na primjer, ako spojite ventilator CPU -a na utikač za napajanje ventilatora kućišta na matičnoj ploči, vaš ventilator ^(CPU)BIOS- a ga neće nadzirati i označiti kao neispravan.

b. Problem s kontaktom^{(Contact issue)} – Ako kabel napajanja CPU ventilatora uspostavi loš kontakt s matičnom pločom, ^(CPU)BIOS će izvijestiti da CPU ne radi.

c. Loš dizajn CPU ventilatora:^{(Poor design of CPU fan:)}  Također postoji mogućnost da je CPU ventilator lošeg dizajna i uzrok vlastitog kvara.

2. Pogrešna instalacija CPU ventilatora^{(Faulty Installation of CPU Fan)}

CPU je instaliran na matičnoj ploči računala, a ventilator CPU je instaliran na CPU . Ako CPU ventilator nije ispravno instaliran, neće raditi ispravno.

3. Prašina ^(Dust) u CPU ventilatoru^{(in the CPU fan )}

Vaše računalo može proizvoditi puno prašine ako se koristi dulje vrijeme. Ako CPU ventilator skupi puno prašine, to će usporiti brzinu procesora^(CPU) i možda uzrokovati kvar CPU ventilatora. Morate redovito čistiti CPU ventilator kako biste osigurali da nastavi normalno raditi.

4. Zaglavljeni ležaj CPU ventilatora^{(CPU Fan Bearing Jammed)}

Ako ventilator CPU -a prestane raditi, moguće je da se ležaj CPU -a zagušio zbog dugog razdoblja korištenja. Ovo je čest problem kod većine korisnika, koji se javlja svake godine ili dvije.

5. Neispravan CPU ventilator^{(Faulty CPU Fan )}

CPU ventilator je komponenta koja se može pokvariti nakon prekomjerne upotrebe. Kada se CPU ventilator ošteti, prestat će se okretati.

Budući da je hlađenje ključno za vaše računalo, čim postanete svjesni problema 'CPU ventilator ne radi', morate ga riješiti.

Kako popraviti CPU ventilator koji se ne okreće

Method 1: Restart the Computer/laptop

Budući da ventilator CPU -a nema zakretni moment, može prestati raditi ako ga ometa prst ili krhotine. Čak i nakon što uklonite prašinu, ventilator će prestati raditi kako bi spriječio izgaranje. Da biste riješili njegov problem, ponovno pokrenite uređaj.

Metoda 2: Očistite ožičenje u lopaticama ventilatora^{(Method 2: Clear the wiring in fan blades)}

Budući da ventilatori CPU- a pružaju mali zakretni moment, žice koje vode do motora ventilatora mogu spriječiti rotaciju lopatica. Uklonite ventilator i provjerite ima li žica itd. koje su ušle u lopatice ventilatora. Kako biste izbjegli da se žice zalijepe za lopatice ventilatora, pričvrstite žicu ventilatora sa strane epoksidom.

Metoda 3: Očistite prašinu ventilatora komprimiranim zrakom^{(Method 3: Clear the fan dust with compressed air)}

Prašina^(Dust) cijelo vrijeme začepljuje ventilatore. Budući da ovi ventilatori ne stvaraju puno okretnog momenta, nakupine mogu pogoditi lopatice ventilatora i spriječiti ih da se okreću. Ventilator možete očistiti rastavljanjem. Ako niste baš sigurni kako to učiniti, zgrabite limenku komprimiranog zraka i ubrizgajte je kroz otvore ventilatora.

Napomena: ^(Note:) Pazite^(Make) da ventilator ne dosegne vrlo visok broj okretaja^(RPM) u minuti ( okreti^{(Revolutions)} u minuti) jer će se oštetiti.

Metoda 4: Zamijenite matičnu ploču^{(Method 4: Replace the Motherboard)}

Jedini način da sa sigurnošću utvrdite uzrokuje li problem s ventilatorom matična ploča je testiranje vašeg računala s funkcionalnim CPU ventilatorom. Ako se ne okreće, matičnu ploču treba zamijeniti.

Također biste trebali provjeriti je li izlazni napon ventilatora procesora^(CPU) između 3-5 V (za prijenosna računala) ili 12 V (za stolna računala) ako imate preduvjete za to. Vaš CPU neće moći raditi s ventilatorom s nulom ili manjim od minimalnog potrebnog napona. Možda ćete morati zamijeniti matičnu ploču i u ovom slučaju.

Provjerite^(Make) je li matična ploča kompatibilna s jedinicom napajanja i ostalim komponentama; inače ćete morati potrošiti još više da zamijenite sve ovo.

Također pročitajte: ^{(Also Read:)} Kako ukloniti ili resetirati BIOS lozinku^{(How to Remove or Reset the BIOS Password)}

Metoda 5: Zamijenite jedinicu napajanja (PSU)^{(Method 5: Replace the Power Supply Unit (PSU))}

Zamjena matične ploče nije izvedivo rješenje u svim scenarijima. Budući da je PSU integriran u matičnu ploču prijenosnih računala, zamjena matične ploče riješila bi problem. Ali, u slučaju da koristite stolno računalo, vaš ventilator ne bi radio ako napajanje od 5V ili 12V nije dostupno. Kao rezultat toga, morat ćete zamijeniti jedinicu napajanja.

Ako čujete zvučne signale ili ako više od jedne komponente prestane raditi (monitor, ventilator, tipkovnica, miš) ili ako se uređaj nakratko pokrene, a zatim se naglo isključi, potrebno je zamijeniti PSU .

Napomena: ^(Note:) Provjerite^(Make) ima li PSU koji ste dobili ima priključke za napajanje identične onom koji zamjenjujete; inače neće raditi sa svim komponentama računala.

Metoda 6: Nabavite novog ventilatora^{(Method 6: Get a new fan )}

Ako ste isprobali ventilator na drugom računalu i ne radi, onda morate nabaviti novi. Kako biste otklonili sve nedoumice prije kupnje novog ventilatora, još jednom provjerite primaju li terminali ventilatora potrebno napajanje.

Metoda 7: Resetirajte BIOS^{(Method 7: Reset the BIOS)}

Vaš ventilator napaja BIOS . Poništavanje će ukloniti pogrešne konfiguracije i vratiti rad ventilatora.

Ako ne znate kako resetirati BIOS , slijedite ove korake:

1. Isključite^{(1. Turn off)} računalo.

2. Za pristup konfiguraciji BIOS -a pritisnite ^{(BIOS )}prekidač za napajanje^{(power switch)} i zatim brzo pritisnite F2 .

3. Pritisnite F9 za ponovno konfiguriranje BIOS-a.

4. Odaberite spremi i izađi^{(save and exit)} pritiskom na Esc ili F10. Zatim pritisnite Enter kako biste omogućili ponovno pokretanje računala.

5. Provjerite radi li ventilator.

Metoda 8: Ponovno podmazivanje ležajeva^{(Method 8: Re-oiling the bearings)}

Ventilator CPU -a može prestati raditi zbog pretjeranog trenja jer je ležaju potrebno malo podmazivanja da bi ispravno funkcionirao. Stoga^(Hence) ga trebate podmazati strojnim uljem i vratiti u život.

Morat ćete ukloniti vrh CPU ventilatora i nanijeti jednu ili dvije kapi strojnog ulja na os ventilatora. Trebalo bi poboljšati njegovu učinkovitost.

Kako riješiti problem da ventilator procesora ne radi?^{(How to troubleshoot CPU fan is not running?)}

Da biste testirali svoj ventilator, pokušajte s zasebnim zaglavljem ventilatora (terminali na matičnoj ploči koji se spajaju na ventilator/e). Ako se okreće, izvor problema može biti matična ploča ili jedinica napajanja.

Pokušajte koristiti ventilator renomiranog proizvođača. Ako radi, problem je najvjerojatnije u vašem ventilatoru.

Provjerite napon između crvenog i crnog terminala multimetrom, ako ga imate. Ako nije 3-5V ili 12V, postoji greška u strujnom krugu s matičnom pločom ili napajanjem.

Alati za dijagnostiku uređaja^(Device) dostupni su na svim računalima. Provjerit ćemo CPU ventilator pomoću ovih alata, kako slijedi:

1. Pritisnite gumb za napajanje^{(power )} da isključite monitor. Za pristup opcijama pokretanja sustava ^{(boot options)},^{( system)} odmah pritisnite F12 .

2. Odaberite opciju Dijagnostika^{( Diagnostics)} na zaslonu izbornika za pokretanje.

3. Pojavit će se prozor PSA+ koji prikazuje sve uređaje otkrivene na računalu. Dijagnostika će početi provjeravati sve njih.

4. Nakon što ovaj test završi, pojavit će se poruka s upitom „želite li nastaviti test memorije. ” Odaberite ^{(” Choose)}Ne^{( No)} .

5. Sada će se pokrenuti 32-bitna dijagnostika^{(32-bit Diagnostics)} . Ovdje odaberite prilagođeni test^{(custom test)} .

6. Pokrenite test s ventilatorom^(fan) kao  uređajem^(device) . Rezultat će se pojaviti nakon završetka testa.

Ako dobijete poruku o pogrešci poput " Ventilator - [Ventilator procesora] nije odgovorio točno",^{(Fan-The [Processor Fan] failed to answer correctly,’)}  to znači da je vaš ventilator oštećen i da će vam trebati novi.

Kako kupiti odgovarajući CPU ventilator?^{(How to buy a proper CPU Fan?)}

Većinu vremena problem s 'lošim kontaktom ventilatora CPU -a' pokreće sam ventilator, što uzrokuje da prestane raditi. To može biti zbog njegove loše kvalitete ili oštećenja ventilatora. Kako biste spriječili takve probleme, korisno je kupiti odgovarajući i pouzdan CPU ventilator za vaš stroj.

Danas postoje ADATA, Intel, Corsair, DEEPCOOL, COOLERMASTER^{(ADATA, Intel, Corsair, DEEPCOOL, COOLERMASTER,)} i drugi poznati proizvođači CPU ventilatora. U ovim trgovinama možete dobiti provjereni CPU ventilator s premium jamstvom.

Kako biste izbjegli kupnju neprikladnog ventilatora, prvo biste trebali pregledati CPU na matičnoj ploči.

Prilikom kupnje CPU ventilatora, jedan od najvažnijih čimbenika koji treba uzeti u obzir je količina topline koju emitira. Ventilator s dobrom toplinskom emisijom sprječava pregrijavanje CPU -a , čime se sprječava da se stroj neočekivano isključi ili ošteti.

7 Ways to Fix CPU Fan Not Spinning

The CPU fan is not running is оne of the most common сomplaints that computer technicians receive on a daily basis. Although the problem seems straightforward, the solution іѕ not.

On the laptop, the CPU fan is normally powered by 3V or 5V, while on the desktop, it is powered by 12V from the Power Supply Unit or PSU. The fan header is the port on the motherboard where the fan connects. The majority of fans have three wires/pins. One is for voltage supplied (red), the second is for neutral (black), and the third is for controlling fan speed (green)/(yellow). The BIOS then uses a stepped mechanism to power the CPU fan. As the device temperature rises above the threshold point, the fan normally kicks in. The fan speed increase as the temperature and CPU load rises. 

Why is Cooling Essential?

Cooling is essential for your machine to function at its best without overheating. This is accomplished by using ventilation devices, coolants, and, most often, cooling fans. Hence fan not running is a cause of concern.

For a computer, PSU fan, CPU fan, case/chassis fan, and GPU fan are all examples of cooling fans. Users had reported that when their CPU fan stopped spinning, the machine would overheat & throw a BSOD. Because of the thermal monitoring system, the machine would shut down. It may not turn on for some time as it could encounter a fan error during the boot process.   This article will address the issue and demonstrate how to troubleshoot it. It includes basic solutions for the scenario ‘if your CPU fan is not running.’

What are the signs to check if your CPU fan is not spinning?

The CPU fan mounted on the processor is supposed to cool it to prevent it from overheating and causing damage. When you first turn on the screen of your computer, you can hear a noise produced by it. CPU fan failure is a common issue that affects all desktop and laptop computers.

If any/all of the following problems occur, the cause could be a malfunctioning CPU fan:

• The computer often shuts down unexpectedly – If it shuts down and does not start unless you push the Power button to restart it, it might be a fan issue.
• The computer can no longer boot – If your computer won’t start, maybe the CPU fan isn’t running. This may damage the motherboard.
• The boot logo does not appear – When you switch on the screen, and the boot logo doesn’t appear, it’s possible that there is no sound from the CPU fan.
• The computer is overheated – When your computer has been running for a while, it reaches a high temperature, and the fan should turn on. If you are unable to hear the fan spinning, it is faulty.
• The CPU fan does not turn on – When you turn on the machine, the CPU fan does not turn on.

You can install a computer inspection tool to check if the computer hardware and software are working properly or not. The app will notify you if it finds that the CPU fan is not working.

What are the Dangers if your CPU Fan is not spinning?

When the CPU fan stops working, it may cause many issues, like:

1. The computer often shuts down unexpectedly – The computer often shuts down without warning, resulting in device malfunction or data loss.

For example, if your machine breaks down unexpectedly, you will not get a chance to save your data. Also, when you restart your computer, all of your data will be lost.

2. The CPU fan stops working – If this happens, it can cause damage to the CPU as well as the motherboard, rendering the machine unbootable.

Also Read: How to Fix Computer turns off automatically

What are the Reasons if my CPU fan is not Spinning?

This could happen because of a variety of factors as listed below:

1. BIOS issues

So far, ATX motherboards have had the ability to track CPU fan temperature and speed in BIOS settings. Thus, there’s no need to physically open the device case to check the CPU fan. Instead, while booting your device, you can enter BIOS settings to do so.

Sometimes, BIOS may not be able to track CPU speed and temperature, leading you to believe that the CPU fan has stopped running.

This issue is most likely caused by

a. The CPU fan’s power cord is incorrectly attached: For example, if you connect the CPU fan to the case fan’s power plug on the motherboard, it will not be monitored by your BIOS fan and marked unworkable.

b. Contact issue – If the CPU fan’s power cord makes bad contact with the motherboard, the BIOS would report that the CPU is not running.

c. Poor design of CPU fan: There’s also a possibility that the CPU fan is of poor design & the cause of its own failure.

2. Faulty Installation of CPU Fan

The CPU is installed on the computer motherboard, and the CPU fan is installed on the CPU. If the CPU fan is not installed correctly, it will not work properly.

3. Dust in the CPU fan

Your computer may produce a lot of dust if it has been in use for a long time. If the CPU fan collects a lot of dust, it will slow down the CPU speed and possibly cause CPU fan failure. You must clean the CPU fan regularly to ensure that it continues to run normally.

4. CPU Fan Bearing Jammed

If the CPU fan stops running, it may be that the CPU’s bearing has gotten congested due to a long period of usage. This is a common issue with most users, which occurs every one or two years.

5. Faulty CPU Fan

The CPU fan is a component that can break after excessive use. When the CPU fan is damaged, it will stop spinning.

Since cooling is crucial for your computer, as soon as you become aware of the ‘CPU fan not running’ problem, you must address it.

How to Fix CPU Fan Not Spinning

Method 1: Restart the Computer/laptop

Since the CPU fan has no torque, it can stop functioning if obstructed by a finger or debris. Even after you remove the dust, the fan will stop running to prevent itself from burning. To rectify his issue, restart your device.

Method 2: Clear the wiring in fan blades

Since CPU fans provide little torque, the wires leading to the fan motor may prevent the blades from rotating. Remove the fan and inspect it for any wires etc., lodged into the fan blades. To avoid having wires being stuck to fan blades, secure the fan wire to the side with epoxy.

Method 3: Clear the fan dust with compressed air

Dust clogs up fans all the time. Since these fans don’t generate a lot of torque, the build-up could hit the fan blades and keep them from spinning. You can clean your fan by disassembling it. If you’re not exactly sure how to do it, grab a can of compressed air and squirt it through the fan vents.

Note: Make sure the fan doesn’t reach very high RPM (Revolutions per minute) as it will get damaged.

Method 4: Replace the Motherboard

The only way to tell for sure if the motherboard is causing the fan issue is to test your PC with a functioning CPU fan. If it doesn’t spin, the motherboard will need to be replaced.

You should also check whether CPU fan voltage output is between 3-5V(for laptops) or 12V(for desktops) if you have the prerequisite electrical skills for it. Your CPU will not be able to operate the fan with zero or less than the minimum required voltage. You may need to replace the motherboard in this case too.

Make sure the motherboard is compatible with the power supply unit and other components; otherwise, you’ll have to spend even more to replace all of these.

Also Read: How to Remove or Reset the BIOS Password

Method 5: Replace the Power Supply Unit (PSU)

Replacing the motherboard isn’t a feasible solution in all scenarios. Since the PSU is integrated into the motherboard of laptops, replacing the motherboard would solve the issue. But, in case you are using a desktop, your fan would not work if the 5V or 12V supply is not available. As a result, you’ll need to replace the power supply unit.

If you hear beeping sounds, or if more than one component stops working (monitor, fan, keyboard, mouse), or if the machine starts for a short time and then shuts down abruptly, the PSU needs to be replaced.

Note: Make sure the PSU you get has supply ports identical to the one you’re replacing; otherwise, it won’t work with all the components of the computer.

Method 6: Get a new fan

If you’ve tried your fan on another computer and it doesn’t run, then you need to get a new one. To eliminate any doubts before buying a new fan, double-check that fan terminals are receiving the required power supply.

Method 7: Reset the BIOS

Your fan is powered by the BIOS. Resetting it will remove misconfigurations and restore the functioning of the fan.

If you don’t know how to reset the BIOS, follow these steps:

1. Turn off the computer.

2. To access BIOS configuration, press the power switch and then quickly press F2.

3. Press F9 to reconfigure your BIOS.

4. Select save and exit by pressing Esc or F10. Then, hit Enter to allow the computer to restart.

5. Verify if the fan works.

Method 8: Re-oiling the bearings

The CPU fan may stop running due to excessive friction as the bearing needs some oiling to function properly. Hence, you should lubricate it with machine oil and get it back to life.

You will need to remove the top of the CPU fan and apply one or two drops of machine oil to the axis of the fan. It should improve its efficiency.

How to troubleshoot CPU fan is not running?

To test your fan, try a separate fan header (terminals on your motherboard that attach to your fan/s). If it spins, the motherboard or power supply unit can be the source of the problem.

You should try using a fan from a renowned manufacturer. If it works, the issue is most likely with your fan.

Check the voltage between the red and black terminals with a multimeter, if you have one. If it’s not 3-5V or 12V, there’s a circuit flaw with the motherboard or power supply.

Device diagnostic tools are available on all computers. We are going to check the CPU fan using these tools, as follows:

1. Press the power button to switch off your monitor. To access the system boot options, press F12 immediately.

2. Select the Diagnostics option from the boot menu screen.

3. The PSA+ window will appear, showing all the devices detected on the computer. The diagnostics will begin to run checks on all of them.

4. Once this test is over, a message will appear prompting “if you want to continue the memory test.” Choose No.

5. Now, 32-bit Diagnostics will start. Here, choose the custom test.

6. Run the test with the fan as the device. The result will appear after the test is complete.

If you get an error message like ‘Fan-The [Processor Fan] failed to answer correctly,’ it means that your fan is damaged and you will need a new one.

How to buy a proper CPU Fan?

Most of the time, the ‘bad CPU fan contact’ issue is triggered by the fan itself, which causes it to stop running. It may be due to its poor quality or damage to the fan. To prevent such troubles, it is beneficial to purchase a suitable and reliable CPU fan for your machine.

ADATA, Intel, Corsair, DEEPCOOL, COOLERMASTER, and other well-known CPU fan manufacturers exist today. You can get a trusted CPU fan with a premium guarantee from these stores.

To avoid purchasing an unsuitable fan, you should first inspect the CPU on the motherboard.

While purchasing a CPU fan, one of the most critical factors to consider is the amount of heat it emits. A fan with good thermal emission prevents the CPU from overheating, thereby preventing the machine from shutting down unexpectedly or being damaged.
