All tests were performed at room temperature of 25°C. Indicated software was run for 20 minutes to create thermal load. Temperature for all Intel P4 processors was measured with Intel Active Monitor software. A ThermalTake XaserII case with front and rear 80x80x25 case fans was used in all tests. Test results may vary depending on case design and air flow.
