Gerbils,
My current setup has a Thermalright Ultra-120 heatsink on an Asus Sabertooth P67 motherboard, and the fan that comes with it doesn't work with the on-board fan controller. I believe this is because the fan is only 3 pin, when I think the motherboard may only be able to control the RPM of 4 pin fans. Can anyone recommend a quiet reliable 120MM 4pin fan that I can use to replace the current one? Price is not a giant concern, I am fine with spending anything under $30 (it better be a really nice fan though!). Thanks everybody for any suggestions you can give!
