after some PC (physical) cleaning, I noticed, that two fans from my AIO liquid cooling are not spinning (I don't know for how long, most probably after cleaning). I swapped the AIO cable from CPU_FAN1 to CHA_FAN3 and it works, so probably the header is not working correctly. I noticed, that a smaller (120 instead of 140) fan works on this header, but very slowly. I also noticed, that if I plug it on an angle (probably the 4th pin doesn't connect) both fans will spin at full speed. I also noticed that temperatures displayed in UEFI are strange (65535, so maximal value for integer 16 bit), but temperatures displayed in OS or memtest are realistic.
Update: other fan controllers are probably also faulty, fans are just spinning at high speed. The only way I can control them is to use a fan controller from my case (Lian Li LanCool II Mesh).
I tried:
- resetting UEFI (shorting pins, no battery, no PSU cable)
- searching for a header mode setting, but there is no such thing in my UEFI. According to some info found on the Internet, it is only PWM mode
- memory test went ok
- setting fan speed to full speed or to profile with speed based on MB temperature.
Systems (Windows 10, Linux) are stable on this machine
Can I do or check something more? Or it's probably a broken header and I should just use another fan header.
my machine:
- Motherboard ASRock AB350 k4 gaming
- Fans from Arctic (PWM 140 and 120)
- AIO Arctic Liquid Freezer II
- CPU Ryzen 1700X
- BIOS 5.80, cannot update because of the CPU
The screenshot from ASRock F-Stream doesn't look right
