3 out of 5 eggsNoisy but works

Pros: Seems to be working fine. No issues installing once I made a bracket.

Cons: Noisy. I had originally set it up for variable control but it was too distracting spinning up and down. So set it to "silent" mode in BIOS and now it's just a background hum I can tune out.

No Brackets. I ended up cutting up a different bracket to make this cooler work. It's a hack I didn't expect to have to do. Thankfully I had installed a different cooler a few weeks earlier and kept the spare pieces.

Other Thoughts: I would have given it more eggs if I hadn't been surprised by the no brackets issue.

5 out of 5 eggsAwesome coolers

Pros: I don't understand why users give these only one egg. This cooler runs great. On a server motherboard you don't need any extra brackets and that's what these were made for, servers not desktop CPUs. If you look at Dynatron's website you'll see these are listed to work for servers CPUs.
I got two of these for a Dual Xeon X5650 (Westmere-EP) setup and run awesome!

Cons: None

5 out of 5 eggsexceeds expectation

Pros: Exactly what I wanted, does the job. Only fits on server mother boards. Used it on multiple supermicro X8DTH-iF's. Good grease, seconds to install, solid wiring.

Cons: none

Other Thoughts: you need to put these on server motherboards that sports a 1366 socket without the need for a bracket..

Severely disappointed!!!

5 out of 5 eggs

Pros: It's cheap and seems to cool well. Easy installation: bolted right onto my Supermicro board's back-bracket; thermalgrease is pre-applied.

Cons: none so far

Other Thoughts: I haven't run my system under full load yet, but so far this heatsink kept both of my Intel 5520s absolutely cool. At full fan speed the case sounds like a plane about to take off - I have them spinning a bit slower which doesn't seem to make a difference for the heatsink's cooling ability, but reduces the noise significantly. I have the box standing right on my desk and the noise hasn't bothered me yet.

Easily fit into my 4U rackmount case. Looks as if they would fit into a 2U as advertised.
