1 out of 5 eggsHorribly loud under use...

Pros: Easy to install
Keeps the CPU around 70-80°F under extreme load

Cons: The copper on the bottom of the fan that touches the CPU is slightly curved... I have no idea what benefit or purpose this serves.
Under heavy load (higher fan speeds), it makes a horribly loud buzzing sound. So loud, it is hard to hear anything else in the room. It sounds like someone is using a table saw nonstop, and I wish that was an exaggeration. It hurts my head after a very brief amount of time. If I put a small amount of pressure on the end of the fan aperture, it no longer buzzes, but this is on my CPU and I can't just put extra weight on it at all times.

5 out of 5 eggssmall and does the trick

Pros: Small and lightweight
does not hinder multiple cpu installations or other components
temperatures at normal load around 40-50 degrees (room temp is 30-35 degrees)

Cons: none so far

Other Thoughts: Have this to cool two Inten Xeon 2620s in an Asus Z9PA-D8 motherboard.
Our server is in an Antec Gaming case with five case fans moving between 70-120 cfm each so noise is not a factor for us.

4 out of 5 eggsNot too bad

Pros: Solid, heavy design and not super loud. Very slim and fits boards that have two CPU's close together.

Cons: If I could dream, all fans would be silent and keep processors frozen. This one is not silent, especially when it kicks on to full speed. But it *is* intended for slim servers.

Other Thoughts: I was surprised by the solid design after seeing the pictures. I have done NO tests for the actual cooling performance. My build is a dual Socket 2011 in a 4U and I used this fan for its slim "horizontal" dimensions rather than its height, but I am changing motherboards and will be swapping in larger, quieter fans since I will have more room.

5 out of 5 eggsSolid Low Profile Fan

Pros: Relatively Quiet.
Copper with good small fins for large surface area.
Can attach self-made exhaust heat directors easily.

Cons: Fin width is somewhat narrow leading to very fast dust collection and will probably require regular cleaning.

Other Thoughts: Blows air out of opening.
Runs slightly oc'd i7-3930k turboing just over 4Ghz.
I might try using this with mineral oil cooling.
