It's very good, much because of it's size. You can even use it as passive cooling if you have a two-fan PSU and a not too hefty CPU (an O/C:ed 2800+ is probably too much ).
The fan itself is a 92mm so it can push alot of air.
There are probably loads of benchmarks and tests out there, just look for them.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
