they can. Quieter too. The SilenX more than the the alpine, but both will do. Like I said, If you want to be guaranteed of overkill, buy the 212 plus. It will fit, it's pretty cheap, and you will never hit 65c even if you overclock it within an inch of it's life. It's just a question of how bad you want to save ten bucks.
hyper 212 plusses are going for 26$, so you got to dig kinda deep to find stuff that is cheaper http://pcpartpicker.com/part/cooler-master-cpu-cooler-rrb10212pg1
This one is $10 http://pcpartpicker.com/part/gelid-solutions-cpu-cooler-ccsiberian01
It's not really any beter than the silenx thoguh.Edited by bombastinator - 10/21/13 at 1:49pm
