I recently bought a AMD FX-8350 and have installed the stock cpu cooler, but man that thing is annoying. It runs around 2.7k rpm ~ 3.5k rpm while idle, and 4k~5k rpm while playing games for like 5 minutes, and it runs idle around 40C. I want a cheap and better cpu cooler, but my case is a antec GX500 illusion, and i won't be able to fit a CM 212 in it, are there any other good alternatives?
