I am looking to upgrade from my Arctic Freezer Pro Rev.2 which has served well, but sadly cannot cope with the maximum 4.4GHZ OC I can get from my Phenom X4 970. I am running it at 4GHZ at the moment and I often get within 6C of the Bluescreen temp. I was thinking Hyper 212 EVO + extra fan, but for sub £35 is there any other alternatives. £40 is my absolute max.
Get the Hyper 212 EVO but no need for extra fan... or get the corsair A50. But id still recommend the EVO. I have it and at speeds below 1200rpm its really quiet, but then it gets kind of loud... but the fan is better than the one on the corsair A50
