There's an interesting review of the Aerocool Deep Impact DP-101 CPU cooler over at Viper's Lair. The review appears to re-hash an earlier review, but it is good none the less. You can read it here (http://www.viperlair.com/reviews/case_cool/other/heatsinks/aerocool/deepimpact/). An example of the slightly unusual approach to some aspects of this review can be gleaned from the following quote from the review:
QuoteI had to know just how efficient it was so I went a little crazy and decided to shut the fan off. I powered down, removed the fan from the motherboard header and after allowing the CPU to cool for 15 minutes powered up the computer and went straight to the bios. The CPU was at 37C when I got the health status screen and I sat there and watched the temperature rise. 45C came and went quite quickly but when we reached 55C a funny thing happened. The climb in temperature slowed down. After about 10 minutes the temperature finally levelled out at 61C. Too high to be of any use but still impressive none the less. I left it like that for about half an hour and the temperature remained at 61C. Now that scared the crap out of me but I was very surprised that I had no lock ups or problems at all. ........Impressive.
This is the CPU cooler that I decided to put in my overclocked PC and I can highly recommend it. It is virtually silent at 24dBa but it cools incredibly well. In the above review it out-cooled a screaming delta set up that pushed over three times the cfm!
