This is on an AM3 AMD CPU(AMD Phenom II X4 965 Black Edition)
My options are:
The Hyper 212
The TX3 Evo
The COOLER MASTER V8
I would not pick the TXe; it has a noisy 92mm fan.
All the others might be reasonable.
If you want the best, look at the noctua nh-d14 or phanteks which have 140mm fans.
The COOLER MASTER V6 GT
Please explain your choice with facts, reviews, or personal experience.
