I'm currently running this in a Corsair 650D case and I'm seeing 28 degree idle, 68 degree peak temps under full and persistent load in Prime95. Conservative OC @ 4.4GHz. I think I could hit 4.6 with me being comfortable with the core temps. I am waiting for the Arctic Silver paste to "cure". So I'm taking it easy before going higher. It's a decent cooler and I'm happy with the value of it. But it could be improved.
I'm using a e6600 volted to 1.43v at 3.33 ghz (fsb limit) and I'm seeing real world loads under 40-45c with the case fans on low and idle in the low 20's high teens. This is in a raven 3 btw with room for more fans So you should be good.
@120 I'd get the raven 3 over any case btw. Idk if you ordered already though...
I have that cooler on that processor, but in a huge HAF 932. I'm running stock speeds right now, but this cooler dropped my max load temps from 85 with the stock cooler to 45 with the hyper 212 plus running Prime 95 in ambient temperature of about 22. I'm planning on doing some overclocking myself, and I expect to get great results with this cooler.
