Likely a faulty fan or the fan is connected incorrectly or the cable is loose.
The cpu fan typically connects directly to the motherboard in a specific "cpu fan" header. The motherboard monitors the cpu fan speed to protect the cpu from overheating.
- 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.
You could get another fan for your 212X to make sure it is not going out, Do you have a fan controller on it? You could put another fan on the back side to make it push pull. Those FX9590 run hot. From AMD Com :AMD.COM
"Warning: This power draw of this CPU is almost twice that of the average CPU. Due to this, AMD recommends using at minimum a 1000W power supply. For cooling, AMD recommends using either closed loop liquid cooling or full system liquid cooling".
You might try a Noctua NH-D14 or a scythe mugen 5, From what I read that 9590 starts throttling at 66C.
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.
