I have a 1060 that it's fan is not running at the correct speed. Normal speed around 75% shows 3k rpm. This one is running at about 2100 causing the temp to be about 6-7C higher than the other 1060. Does anyone know where I can get a replacement fan or what size the fan is, how many screw holes on the fan, center to center screw spacing on fan? I don't want to RMA because the process takes so long. Thank you.
