Cpu Fan Error

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.

 

What exactly does the error message say?

Is the CPU fan spinning up? If you gently flick the fan with finger, does it spin freely?

How much time passed? That is, did the computer work fine for weeks, months, years(?) before this error started to appear?

Did you make sure the fan cable connector is securely fastened to the correct fan header on the motherboard?

What are your CPU temps?

If your CPU temps remain good, and you are sure the fan is spinning up fine, you can probably disable that warning in your BIOS Setup Menu.

 

Thanks for your reply.

Here is a screenshot (not mine, googled it but the exact error)

Yes, the CPU fan is spinning up and working and yes, it spins freely to a bit when flicked gently.

Yes, the PC was smoothly running for years, like 5+ years.

Yes, I'm sure that everything is well-connected and not loose.

CPU temps are ranging between 40's and 50's in Celsius.

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".

 

It would seem a fan sensor is faulty, but not sure if in the fan itself or the motherboard. Since you are sure the fan is spinning and your temps are good, I would look around in the BIOS Menu and see if you can disable that warning.

 

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.

 

And what are your temps now? 65°C at idle is too high.

 

Load % of CPU fan : 75%
CPU Temp. : 49C

 

Okay. 49°C is fine.

 

I would advise swapping in a known good fan for purposes of process of elimination.

This would rule out the sensors on the system board.

 

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

 

I'm glad you got it sorted out and thanks for posting your follow up.

 

You are most welcome bro., thank you as well for your time and effort
