Just a short review on this one more so to give an idea of performance.
Firstly I'll get the cons out the way. It is big and heavy. I doubt it will do damage to the mobo, but it was a surprise to me how heavy it was.
As for the size, it is about 12-13cm tall so make sure you have enough space in your case before buying.
Now with that out the way let's get to the good stuff
Ambient Temp - 20 degrees
CPU idle Temp - 25-26 degrees
CPU load Temp (Prime 95) - 52 degrees
CPU highest Temp that I've recorded since purchase - 55 degrees
In my opinion these temps are spot on for my i7 running at 4.5Ghz with 1.214v.
Being an air cooler it is silent, and the cooler itself also features some fan mounting brackets which can be used to help pull/push the air through the cooling fins.
When I was purchasing, I was deciding between the H80 water loop from Corsair or a large heatsink. The prices were the same, and since I already have a case with several fans in, I didn't want a radiator as well so I settled on the large heatsink.
So far I've had no problems with it, and am very happy with my purchase.
