Tests were conducted under idle and load states. The computer was left to sit after 30 minutes after being turned on to check the idle temperature. The load temperature was found by using four instances of Prime95. Temperatures were obtained through SpeedFan.

Zalman CNPS9300 AT
The Zalman CNPS9300 AT outperformed all of the other coolers in idle temperatures by a full 3C. It was still pretty close to our best 100% load test, but I really think that low idle state would produce better cooling for the average user considering I'm sure most people don't run their CPU at 100% often.
I found the Zalman CNPS9300 AT CPU Cooler to be quite powerful. While it's not the `sexiest' as some may like it still does its' job very well. The low temps, especially the idle ones, are what makes this cooler excellent for cooling. Finding this product for around $45 at many online retailers seems to be a typical price among CPU coolers. If you really don't care about Blue LED's or fancy designs, but enjoy low CPU temps I think this would be a great pick for you. ThinkComputers awards the Zalman CNPS9300 AT CPU Cooler a 10 out of 10 score and our Editor's Choice Award.
