Im sure this has been asked 100's of times before but what it the best cpu cooler for under 40 dollars that will work with an am3? also the mobo is the asus m4a89gtd pro/usb3... I was thinking the hyper212 or ZALMAN 9500A-LED.
Cooler Master Hyper 212 plus is good. But if your going to change the fans on them then it's going to cost you a bit more depending on what kind of fans you are buying. For example i see people buying the Cooler Master Hyper 212 plus for $30 and buy a set of fans that range from $10-$25 per fan. So in a push pull it's going to cost them around $50-$80 depending on what fans they installed. Also they have the Corsair A70 at Tiger Direct right now for $34.99 with free shipping...Not sure if they made a mistake on the price but that's pretty cheap.
