What heatsink will overclock a core 2 duo to 4ghz?

I was wondering what Heatsink should keep my cpu at safe temps @ 4GHz

My cpu:
Core 2 duo e7300
Base clock - 2.66ghz
Cache - 3mb


Asus P5n-D

Viotec 550w

I was thinking, will a hyper 212+ work?
Corsair h60 water cooling?

I want to do this because I plan to run 2 gtx 460's in sli, to limit bottleneck, then just transfer them over to my i5 when I build it, this is just to hold me over.

  1. I'd stick with a CM 212. As a stop-gap solution, it doesn't really make sense to spend all that much on it and the difference between a 212 and H60 isn't really going to be worth the price.

    Overclocking is highly variable. There is no certainty your chip will reach 4GHz, or if it does, how much voltage will be needed for it to be stable (higher voltage = more heat). You can find cooler reviews at HardwareSecrets also tests coolers. In general, with a decent fan on it, one 120mm direct-touch tower cooler will be within a few degrees of another. I would suggest one from Xigmatek, Corsair, or Noctua.
  3. Seems if I attempt for a 4ghz clock, Ill trust in a hyper 212 with some nice push pull 120mm fans. If I get there, do you think a 212 with aftermarket fans should keep it cool under stressed games like bf3/crisis?

  5. Thanks. I will never recommend a CM product because they have been caught by HardwareSecrets in some pretty flagrant acts of dishonesty. They may have some other products which are excellent, but a rational individual does not support dishonesty. That is why I recommended the others. I have a Xigmatek Gaia myself keeping my 4GHz Phenom II at 31C right now.
