I bought this to sit on top of my i5-2500K and I couldn't be happier. I love the way it looks through the case's side window and it is so quiet and smooth. The installation was easy enough, anyone with mechanical ability should have no trouble and the chrome and polished metals are great and give it a much better appearance than most cpu coolers. I was surprised when I first saw the box, it is not as big as I expected. Though not small it is not huge and doesn't feel like a brick in your hand.

I think other coolers available could keep temps a bit lower but mine are fine. I keep my 2500 overclocked to 4.2 and it idles at 42c and under load gets up to about 60c on a hot day. I don't believe in "burn-in" or "stress" testing but would expect core temps to near or pass 80c during such tests.

I also love that it is from Intel who better than them to know what their processors need?

I would recommend this fan to all except possibly severe gamers who need every bit of cooling they can get.

This Fan is super quiet and is very big inside your case. But it low my temp to 10 C degree less comparing to the standard fan that came with the cpu. It has two speed you can adjust with a button.

With the higher speed it give a little more noise(useful in summer period).

Also you must install it first before screwing the Motherboard in your chassis because you have to fix the base under the Motherboard first

You also have to remove the fan cover to be able to fix the screws in the base.

Also make sure you buy the latest model with the speed button included with the transparent plastic fan, because there are a lot with the same number.

I recommend this quality Fan to everyone !

Works well. A little bit of a pain to install but if you know computers you should be able to handle. I would not hold off because of that. Just remember when installing take grill off from in front of fan.

Using for a month now with no problems. Also quiet.
