Hello, I found a cooler master fan in another pc in my house we arent using and I was wondering if It would be an upgrade from my Intel Core 2 duo e6700 2.66ghz stock cooling. It is aftermarket on the computer and its cooling a 3.0ghz pentium 4 and I want to put it on the dual core I was talking about and I was wondering if It would be better than the stock cooling. This is the fan=== http://store.cwc-group.com/comaxiforinp.html It says it will keep a 3.8ghz P4 prescott cool.
