Pros: Great cooler,
on my E6750 @ 3.0Ghz it dropped idle temps by about 2 or 3 degrees but dropped the load temps by about 10 degrees
also came with some thermal paste
great price for a high performance cooler

Cons: a bit loud at full speed, but when used with a fan controller (like sku 9264) runs nicely @ 1100rpm

Other Thoughts: easy to install with the fan held onto the heatsink with rubber knobs

the heatpipes are showing the whole way across the bottom of the heatsink (not too sure if this is a good thing or a bad thing) so there are slight gaps between them and thermal paste MUST be used.

Bottomline: Great cooler for a great price!

Pros: - Good cooling performance in comparison to the stock intel cooler.

- Very easy installation. Took me 15 seconds.

- The 90mm fan pushes the hot air from the CPU directly into the rear exhaust fan or into power supply, so heat doesn't build up in your case.

- This cooler directly touches the CPU heatspreader with it's heatpipes, for improved thermal conductivity.

- The 90mm Fan installed pushes a considerable amount of air, and has yellow rubber things to keep it in place and reduce vibration at the same time.

- Comes with thermal paste pre-installed, but I wiped this off and used AC5 for my testing.

Cons: - Fan is louder than stock intel one, but this is probably because it spins a lot faster. The fan can be controlled to be quiet however. None the less you probably wont be able to hear it over your other case fans.

- Only supports Socket 775, but the box says there is another version for other sockets (AM2, 939, etc).

- Price is a bit high.

Other Thoughts: Tested with a Celeron D 347 @ 3.9 Ghz, with the stock intel cooler it idled at 37 degrees and under load was 48 degress. With this cooler it idled at 29 degrees and was under load at 38 degrees.

Bottomline: Very good cooler if you are planning on some mild overclocking or you have a very hot chip. Worth it.
