OCAddiction takes the top 2 contenders of P4 air cooling and pits them in a head to head deathmatch. Metal to Metal, Pin to Pin.
To test the real potential of the heatsinks, I've included no case fans in the test bed. I used a temperature probe on the processor and the Northbridge passive heatsink (just because I had two). A fresh thin layer of Arctic Silver II was applied on the processor for each heatsink. The case sits tightly under my desk during the testing procedures. The fan I used was the Sunon 80mm x 25mm fan. It is a very common fan used for CPU HSF's and blowholes alike. It's also relatively quiet and provides a steady stream of 36CFM. The ambient room temperature was kept at a constant 73F.More information at OCAddiction
