Hybrid Posted October 12, 2022 Share Posted October 12, 2022 So the PWM controller on my HD 6970 is dying and started freaking out, So i made an adapter and connected the blower fan of the card to the motherboard, but the PWM signal from the motherboard is not good for this blower fan. Now i don't really now what to do, I thought about using something like a rasperry pi or arduino to provide a PWM signal to the fans. But i don't know how the signal should be since i don't have a HD 6970 with good PWM signal to measure. Is there a way to ensure that the duty cycle and RPM are synchronized? If there is a better way to do it i would like if you let me know Quote Link to comment Share on other sites More sharing options...
