So a while ago I picked up a Coolermaster Hyper 212 EVO for cooling on my processor. It works great and I love it! But the fan went out and doesn't spin anymore. I've never bought just a fan and I was wondering if you guys have some suggestions? Something quite, 120mm. and under $20. I have the clips for it to mount to the heat sink as well.
A couple things. First, the fan you linked is a 140mm fan and probably won't fit on your EVO without modification because it takes a 120mm fan. Second, you'll want a fan that supports PWM so you can keep things quiet.
The Corsair SP120 fans suggested above are a good choice. Might as well get the two-pack so you can set them up in a push-pull configuration on your EVO.
