Pros: This device will move a lot of air and cool things down a lot. We have only run it for a few hours, but it seems very solid and reliable.

Cons: This cooler sounds like an aircraft engine starting up (53dB), very noisy. It pulls 1.6A at 12V and creates a lot of electrical noise (2.1V spikes at 12V).

Overall Review: We were planning on using this on a piece of test equipment, but the electrical noise was just to much for the extremely sensitive circuits to handle. This is a good solid product if you need it and can put up with the noise. The electrical noise did not affect the PC.

Pros: Move a lot of air. Relatively quite. Very inexpensive. Small...great if you are strapped for room.

Cons: None that I have found so far.

Overall Review: I was skeptical that these inexpensive, low profile coolers would do the job for my dual-Xeon (2x6-core) Xen server. They move a surprising amount of air and are keeping my over-worked Xeons nice and cool.

Pros: Size. Built well.

Cons: Does not fit ASUS P9X79MB. They require the Square Type. Doesn't cool quite up to par but well enough for stock settings.

Pros: These CPU coolers are top shelf and well built. Worth every penny.

Cons: None
