i have a 955be thats running at 40 idle and 57 full on stock heatsink
this is 2 high for me, also its always running at 100% and its loud if, i adjust the fan speed the idle temp will go to about 50, so i need a new cooler, im on a budget and narrowed it down to these heatsinks
Based from the options you posted, i suggest go for the CoolerMaster's Hyper 212
Plus, Not only it performs better than the other options you posted but, by carefully
reading and analyzing its reviews on its website, it gathered many awards and
recommendation that indicates its a good and reliable CPU cooler that you could
use for a very long time and its also cheap as well.
