Pros: Excellent cooling capacity, most stock CPUs will be cooled near silent, packaging is nice, build quality is great.

Cons: Size, only comes with one fan. Not a fan of the chrome covered plastic beauty caps for the heat pipes. But i

You must plan for the size of this thing or you wont be happy!

Other Thoughts: Phenom 955 @ 4.1ghz, 1.5v - 58C
Asus Crosshair V
Corsair Dominator 16gb
Rosewill Blackhawk Case

I purchased this because I had a Corsair H60 fail on me. I decided I wanted something that I could just replace a fan if that failed, or even run it as a passive (downclocked cpu of course) if need be.

Just barely fits inside the Rosewill Blackhawk Case!

I also mounted this unit with air flow going vertical instead of horizontal. This way if the fans (i added a 2nd fan) fails, convection should help keep it cool-ish. This should also work better for the heatpipes, as they can be sensitive to gravity (not proven with this particular unit)

It does have problems clearing the Dominator ram sticks I have, I removed the top heat sinks from the ram and the unit fit. It is also worth noting that you can mount the fan higher up on the heatsink if you need too. This might expose parts of the fan to open air, but you will gain some clearance.
