Though't I'd used my old hd6870 with a dead pwm pin - for htpc purposes, the gpu itself works fine, but its reference fan is always 100% which is very loud and annoying. So my question is, what is the best way to slow down its fan? Doesn't have to look pretty, can be with resistors (but specify ohms and watts in that case.)

What about removing the fan and attach an 80mm fan to the shroud above where it was? Or removing the shroud and angling a 120mm fan to blow through the fins? Or even better, if your motherboard is capable of modulating fan speed via DC current (ASUS boards can on most headers) you could rig a plug to them.

if the hd 6870 is old than warrenty may not be an issue if so an oversized aftermarket cooling fan will provide more cooling and not have a brocken pin

and it may be quieter even at full speed.

as well most videocards like cpu's can benifit from more cooling unless they came from the factory with a water cooling kit.
