I've been having this issue of not being able to detect my fan speeds for my CPU cooler, and I need to replace it anyway because when you're a gamer a stock cooler simply isn't good enough usually. (I hit 75C when I was running Crysis 2 maxed out on my 750K), and the cooler sometimes starts speeding up and then back down every few moments during a long session on gaming.
Anyway, my case is an AZZA CSAZ-206, and I need a new cooler for the above reasons. I am on a budget, plus I'm cheap as hell sometimes, so I thought a Hyper 212 of some kind would do, but I am no good with math/measurements. Any recommendations for a different cooler within like 35 bucks that fits an FM2/FM2+ socket are also welcome.
