5 out of 5 eggsQuality Kit

Pros: Installation
Cooling Potential

Cons: None

Other Thoughts: Typically installing a new CPU heatsink is reason enough for me to want to throw myself over a cliff. Prolimatech has somehow transformed this nerve rending experience into a dream. Installation kit is minimal, simple, quality, and effective.

I installed a Noctua NF-P12 120mm PWM fan with my cooler and it is breezy. My i7 3770k (@ 4.2Ghz) just touches 90c on its worst core in a Fractal Design Define Mini case (sound insulated with minimal venting) under Intel Burn Test. It sounds bad, but IBT is unrealistic and I'm using a very enclosed case. Other stress tests leave me in the mid 70s(c).

Buy this heatsink if you want the good stuff. Add the Noctua fan if you want solid temps with virtually zero noise pollution.

5 out of 5 eggsGreat!

Pros: I have this on my Ivybridge i5 CPU and the fan I put on it failed multiple times. I never noticed each time. The thing keeps my CPU cool even passively.

Cons: It is so large that it blocks out one RAM slot on my motherboard. Sacrifices are sacrifices I suppose

Other Thoughts: Technically this is a different listing, but matches the Prolimatech Megahalems Revision B cooler that I bought. I am sure this is the same, and if it isn't then I bet it functions even better.
