I have a P4 2.8GHz with HT installed with a genuine intel heat sink fan. Still when my CPU usage is maxed my cpu temperature reaches 60 degrees celcius. I have 2 additional case fans blowing out of the case, a big powersupply fan also sucking air away from the cpu out the case and a fan in the front blowing air into the case. Is this setup the most efficient for airflow inside the case? When my pc is idle, the cpu temp. is 48 degrees celcius.

Cheers
