I have 6 dedicated servers at intelenet here in California at the moment. After an extensive period of tests I have noticed that the northwood P4 core runs much cooler in a 1U case than a prescott P4. It is known that the prescott core produces more heat due to the amount of power it provides. It just happens that the first server I built was a 1U prescott LOL! Just ordered a northwood to fix the heat problem in that server!

I will let everyone know how it goes!
