Question CPU Fan error

[Hesham_3del]

Hey all,

So, everything was just fine with my prebuilt PC until I got that CPU Fan error thing.

At first, I used to bypass it by restarting the PC several times until this screen goes away and login normally.

I made a complete hardware cleaning to remove dust and such as this maybe the reason behind this error, but still the problem is there.

My BIOS is updated and I did a "clear CMOS" by removing the battery for 5 mins. and putting it again but nothing happened, problem is still there.

Using AIDA64 I looked into the V12 of my PSU, it's good, 11.9xx.

Also, two times since yesterday, the PC was shutting down immediately after powering up.

My PC specs is as follows,

CPU : AMD FX-9590
Motherboard : Asus Crosshair V Formula-Z
Cooling Unit : Cooler Master Hyper 212X
GPU : AMD Radeon RX 560 4GB
Memory : 32GB, 4x Kingston HyperX 8GB

Thanks in advance.

Please include the exact model of your PSU too and how old it is.

is the fan for you cooler plugged into the cpu fan header?

That seems like an old build. Try spinning the CPU by hand gently. If it only spins a couple of times or if it struggles to move at all the bearing might be shot and not spinning and therefore reporting that the RPM's are too low to the motherboard.

I also asked for the PSU because the 9590 can be reeeeeeally power hungry and a non-modular PSU can struggle to distribute current(?) correctly when it's stressed.

What does non-modular vs modular psu have to do with anything? There are crappy modular psu's and great non modular psu's and vice versa.

This is very important on some asus boards!

In that you are totally right, I actually meant cheaper ones (modular consumer PSUs tend to be of better quality on average). Cable modularity itself has nothing to do with the possible problems. However, I won't edit my original post and make a fool out of you =D

Oof! Please delete

Yup, I just misread lobz post. Nothing to see here

Thanks for all your replies.

- PSU: Bitfinex Whisper 750W and it's like 3-4 years old, it's full modular/modular PSU.

- Yes, the cpu fan cable is plugged into the appropriate cpu fan header

Here are some updates which may help in my case

- The PC barely started working today, always shutdown before that error appears or while booting up/entering the BIOS.

- When the PC booted into Windows once today, the fans were super quiet although they were adjusted to "Standard" and not "Silent", the silence was up-normal and here are some reading from the BIOS,

- I've noticed that when I adjust the CPU and Chassis fans to "Turbo" the temperature increases till the PC freezes.

- Was converting some videos for the family, the PC freezes when it reach 65C - 70C although it's set in the BIOS to protect from overheat at 90C- 100C.

- The PC is running smoothly now by putting a large fan in front of the open chassis and setting the fans speed to "Silent".

Here is a small update but I think it will put the last nail in my issue's coffin,

I've stopped using the desk table fan and set the fan speed/mode into "Silent", the PC restarted and on the 2nd windows login, I've got an warning that the CPU temp. is 65C so I raised the fan speed to "Standard"

No load were done during that temperature rise, just web-browsing.

Also, mainly on the restarts, I don't see that CPU Fan error and sometimes also on the first boot-up.

Have you tried removing the cooler and reapplying thermal grease?

 

[Hesham_3del]

Finally, problem solved.

The problem was the cooler's fan, it was not rotating freely when I spin it compared to the fans of the case for example.

So I've replaced that failed fan with one of the two case fan's and it works well.

I faced an small issue with it today as it was rotating at nearly 5xx rpm while on "Silent" mode and got the same error, so I simply lowered the minimum speed limit to 500.

Also, my back panel fan was having that CPU Fan error, this was due to putting that fan on control a.k.a. user control, so I disabled the control and made it automatic up to the system from the BIOS.

Thanks all of you for helping me out, it's greatly appreciated.

Have a nice day
