Hello there...i have a GTX770 4GB where FANs not spinning, because PWM Pin is not supply anything. On Startup fans shortly spin up (0.5sec) and then stand still. set fan PWM to 100% with MSI afterburner shows 100% in GPU-z but still no PWM on pin. Also testet other Bios. i have tries to track the trace from PWM 4-Pin fan connector, but can absolutly nothing find on PCB :-/ so i think the PWM signal comes straight from GPU...but is it possible? GPU is working fine, no graphic issues, works also hours on benchmarks...all fine, except the Fan controlling |
