aka_STEVE_bWell , I'd either leave the fan on all the time or just make sure my case had great airflow to keep it cool enough,.. because opening up the inside of a PSU after it's been in use is Extremely dangerous >>!! I highly advise against it , unless you are an expert at wiring & capacitor discharge procedures. Units will hold power inside for quite some time after being unplugged .. Maybe consider taking it to a computer repair shop & let them replace the fan/ diagnose it .?
munchbunch85Is it a standard 3 or 4 pin header fan? PWM or not?
bob16314munchbunch85Is it a standard 3 or 4 pin header fan? PWM or not? Should be a for the fan and a standard case fan of approximately the same airflow would work if you cut off/splice the fan's +/- wires to the mini connector..It's DC voltage controlled..I don't think the issue is the fan itself.
bob16314The fan controller is borked, probably.
bob16314Yes, and you can't replace it.
