Good cooler under $40

Solution


less RPM because it cools better, the loud fan can be changed. I have the 212 evo myself and I cannot close my side panel its too tall. lol. verify before purchase.
I linked to the entire list but suggested the best bang for the buck.
the i32 is good too

"Verdict: By a wide margin, Deepcool's Gammaxx 400 has the best performance-to-price ratio of any cooler I've recently tested. It will remain on the top of my purchase list until something with even greater value comes along to replace it."

there are others on the list shop around.
you will need to verify that the cooler works on the socket.
