Erreur de ventilateur CPU

Hello,
I haven't read everything so maybe what I'm about to say has already been posted. Open your case and check that the fan on the heat sink is properly connected and in the right spot, as this error is extremely common. If the error persists, clean the heat sink well, and check that the cable isn't damaged!

There you go, good luck!

Hello,
when you buy a new motherboard, you should always format the hard drive to avoid issues!
Then CPU fan = fan error. Either the fan is not properly attached, or it’s dead, or there is a poor contact between the processor and the heatsink (thermal paste).
Last thing to check: make sure the fan is properly connected to the motherboard on CPU FAN as there are several slots for fans. @+

Hello everyone,

remipele has given the answer, this BIOS alert about the CPU fan speed can mean:

- the fan is not spinning: check the fan, if it's not connected to the right socket or is faulty;

- the fan is spinning at a speed that is too low for the BIOS, which is very common with temperature-regulated systems, because at startup, the CPU is cold, so the fan speed is minimal!

Solutions: either it's adjustable in the BIOS, and we change either the alert threshold or the minimum fan speed,
or it's not adjustable, but since everything is normal, we disable the BIOS alert to have peace.

I received the message, with an Asus card, and with a very quiet, adjustable fan.
I had set it to the minimum!
I ramped it up a bit and the message doesn't come back anymore.

Hello Katsuo,

the clear CMOS doesn’t change anything, you need to disable the alert option in the BIOS

On my 2nd PC, I have an Asus A8V-VM, and the CPU fan starts at 700 RPM, which triggers a "CPU fan error, press F1 to continue" because the alert threshold is set at 800 RPM and is non-adjustable

I disabled it by choosing "disabled" for "Wait for F1 if error", in the "boot settings configuration" menu,
and since then the PC boots normally, but if there is another problem, it will also boot

I think we can also disable the CPU Fan reading in "hardware monitor"
and thus not get this alert at startup, but another alert will wait for F1
(I haven’t tried)

the settings should be similar in the BIOS of your Asus M2N

In the Asus BIOS, if you look in the last tabs, there's an option: Wait for F1... a message like, set it to disabled and your computer will beep but it'll start up. I have an E2180 dual core which doesn't heat up much and a large tower cooler, the message doesn't worry me because it's true that it's a big cooler for a processor that doesn't heat up, so the fan runs too slowly at startup. That's precarious but that's how it is :P

Hello,

I have the same problem with a PC I built for my mother, but I also believe it might be related to the BIOS. I have an Asus M2N motherboard with an AMD 4400+, but since everything is cooled by a passive cooler "thermalright SI-128SE with a noctua 120mm fan running at 1200 RPM, I get the message "CPU fan error" at startup, but by pressing the F1 key, everything works fine. I will check with ASUS to see if a BIOS flash could fix the issue.

As for me, I have an ASUS M2N-SLI motherboard with an AMD 5000+ and a Cooler Master Gemin2 cooler + 2 noctua 120mm fans running at 800 RPM, and everything works very well without any error messages.

Hi.
Hmm, it's reporting a bug with your processor's fan, so you'll need to open the PC and check if the fan is working properly, and if it's not running, then you'll need to replace it.

Well, the same answer as before, you don't have any problem to solve so no flashing to be done.

You just need to find in your BIOS where to disable the error message.

You have a good cooling system.

At my place, below 1800 RPM, I get an error message even though my system runs well below that constantly.

So try to check on that side.

Hi guys, I just solved the problem by flashing the motherboard's BIOS.
Easy with Asusliveupdate. Since then, no more messages and the fan is running great without overheating.

Hello everyone, I've read the different posts and it turns out that I have pretty much the same problem. First, let me give you my configuration:

mobo: MSI MS-7050
processor: AMD Athlon 3200+ 64 bits 2000GHz socket 939
RAM: 1.5 GB
GPU: ATI Radeon Xpress 200 series

Here is my problem:
I wanted to change my motherboard and everything else into another case, which I did.
At startup, it starts normally but then it shows me the following message "CPU fan error" and shuts down the PC after 2 seconds.

Thank you for your responses.

Hello
I have the same problem on my PC because I changed the motherboard and the processor, but the thing is I have a fan, but it's not the same type of plug as the CPU fan; it's on the CPU CHA fan
So I think I'm going to add another fan or reinstall my software, but if we can disable it in the BIOS, I wouldn't mind some advice; at least that would save me from doing all that work

Thanks

I recently had a "Fan error," it didn't even prompt me to press F1, it just shut down completely.

When I opened my laptop, I saw a lot of dust in the fan.

So I just brushed it with a makeup brush (the bristles are super soft, so it doesn't damage anything) and blew to remove the dust... and miracle, it worked again!

If this can help some people :D

Hi, I would like to know your PC configuration because I have the same problem with my Athlon 64 and an Asus K8N.

Thank you in advance.

check a problem with the fan or the fan power supply

if the fan does not spin, swap the power supply with that of the case chassis to see if it is the fan or its power supply

Hello,

I have the same problem
Please let me know how to solve it
I am a novice so I need precise explanations

Thank you very much in advance

Hi, go to this address to download this software: cpuz
https://www.commentcamarche.net/telecharger/utilitaires/6615-cpu-z/

With it, go to the 3rd tab "mainboard" and you will find the name of the manufacturer, the motherboard model, and especially the BIOS version. Let us know the details and I'll help you afterwards.

Salut les amis, bon concernant le message "cpu fan error", c'est facile, il y a deux types : soit le ventilateur qui ne tourne pas, alors à ce moment-là, il faut le changer, ou bien c'est un faux message venant du bios et il est facile de le désactiver. Vous allez au bios, vous suivez les étapes, et quand vous trouvez "cpu", vous faites "ignore" et après "save" et vous quittez. Bonne chance.

Hello
I keep getting the same message at startup, and it asks me to click F1 to continue. This happened after I changed my fan, which has become unbearable and is making a lot of noise. I don't know how to solve this problem, please help me.
