The EVO 120 is excellent. I use a SilenX on top at 5v and it still keeps the system cool at 30/3 idle and then up to 40/3 on load. Actually I didnt connect a fan properly and afterplaying CS:Source for 2 hours and it only hit 44 - not bad I thought. With the akasa on 12v I think it would cool into the late 20's at idle and mid thirties at load.
Excellent cooler - loads better than Arctic Cooling and if you have a 120 at the back it makes a perfect through flow section.
10/10 - fits all CPU's as well
