Great for DIY 2U Server
I used this to cool an i5 CPU in a 2U custom server. It has been running for a few weeks now and has been great. Only complication I really had was choosing mounting orientation as the motherboards RAM or heat sinks can block the intake/exhaust due to the coolers low mounting height. Low profile memory worked great for me. I would suggest replacing the factory fan with a Noctua PWM fan. It is now completely quiet and performs excellent. Pros -Fits very well in a 2U server chassis. -Fan replacement is very easy. (See Con below) -Solid core of copper with shroud to direct exhaust in desired direction. -Heavy due to large copper heat sink. -Motherboard mounting was very easy. Cons -The factory fan is super loud. I replaced it with a Noctua PWM fan and its quiet now. -intake or exhaust may be slightly blocked by RAM or heat sinks on motherboard. Low profile memory allowed me to exhaust out the back while only slightly blocking part of the intake. Performance was not impacted in any noticeable way.

Pre-applied thermal paste makes for an easy install
Quiet and Cools Perfectly, Fit's nicely into the Alienware Aurora R8 Case and That's why I chose this model.

Not a Bed!
Great cooler for the size, would recommend something a little lower on the TDP scale if you plan on replacing the jet engine fan like I did. I replaced with a noctua 60x60x25 and now its super quiet even at full blast.
