I am having a PWM 4 pin fan to which i had connected to the motherboard rear fan header i.e air outlet fan
Before today i was able to control the speeds of the fan using bios or by using speed-fan but today i am not able to control the speeds neither by bios nor by speed-fan. Changed the fan also still nothing speed of the fan remains at its lowest speed which is 800 rpm or whatever the lowest speed of fan is. I used this fan with the front fan header and pwm was working but with rear fan header from today it is not working.
Is my motherboard rear pwm function went bad??
i had also not changed any setting in my computer which might cause this problem.
My motherboard is out of warranty.
Hello Rprathin, this kind of behavior could be expected after a BIOS updated or if could be a defective fan.
