Summary: Dropped my processor temps 50ºF immediately.
Pros: Easy to install, efficient, perfect fit on a SuperMicro 2U server board. Speed adjusts as needed when temps change (though that is actually controlled by the server itself).
Cons: Loud! Sounds like a jet engine taking off. Definitely not something you want on a machine in a user environment. The power cable on the fan is a bit short, so creative cable routing is difficult.
Pros: Probably works fine on Xeon processors fine.
Cons: Is not compatible with Intel® Desktop Board DX58SO as its an I7 core, even though the socket lga1366 matches. The Heat sink is too wide and hits the capacitors next to the socket. Nothing on the item page states that this is for lga1355/56 XEON only processors.
Summary: I'm using a pair of these on an Asus Z8NR-D12 server motherboard and it fits like it was made specifically for it. Installation was a breeze as you cannot tighten it too much with the built-in stops. Cooler hardly gets warm strapped to an E5520 Xeon cpu.
Pros: Compact, nicely engineered, great price and very quiet.
Pros: It's a fan that's capable of cooling my CPU.
Cons: This is the loudest CPU fan I've ever heard. The people who said this fan was quiet were being sarcastic, really. The fan produces a loud and high pitch sound that I can even hear over my dehumidifier. You won't drift into sleep with this fan installed and you'll need a hearing aid in the near fu...
Summary: Always check your case space and motherboard heatsink mounting brackets before ordering a heatsink. I purchased these after RMAing the original heatsink/fan I had purchased because it neither would fit the dual-CPU setup nor the already permanently attached mounting bracket.
Pros: Fits perfectly to the motherboard and LG1356 CPU, and fits in a dual-CPU scenario. It's relatively quiet, comes with thermal paste already applied, and very easy to install.
Pros: Fit nicely in a Supermicro X8DTL-if-o dual cpu board. Kept CPU's cool.
Cons: Louder than Chuck Norris. I returned them because I got tired of people in the office asking me where the jets were landing, and that was with the server in a separate room with the door closed. I gave them 5 eggs because they are a good product and they do what they are meant to do - keep the cp...
