Graphics Card Fan Not Working

have you tried using a third party program to make the fan work, if not, try msi afterburner or evga precision.

i have evga precision running but cranking the fan speed up does nothing.

Your first mistake was buying Sparkle. Sorry, my opinion, worth every cent you paid for it.

Fans die. Sparkle doesn’t put a great deal of attention into small stuff like fan life cycles. It’s probably burnt out. What Dnx means is that you should by a new fan from another manufacturer and replace it yourself. Barring that, RMA it back to Sparkle and let them (pay them to) fix it.
