"Why are ATHwiper HeatSInk-Fan combinations so much bigger than those for Intel's Pentium 4?" First, you better check the sizes one more time. Second, it was already explained to you: the P4 does not run at 1.5GHz, most likely it throttles the clock by half when doing real calculations, so effectively it runs at 750MHz. Got it?

Paul, Why are ATHwiper HeatSInk-Fan combinations so much bigger than those for Intel's Pentium 4? I found the answer to this and some other P4 questions at: ftp://download.intel.com/design/pentium4/datashts/24919802.pdf The Thermal Monitor feature (refer to Section 7.3) is intended to protect the processor from overheating when running high power code ..... When TCC is enabled, and a high temperature situation exists (i.e. TCC is active), the clocks will be modulated by alternately turning the clocks off and on at a a 50% duty cycle. This explains how they keep power consumption, temperature, and most importantly- performance down on P4. They have a double speed ALU, which runs at half speed to keep from overheating. This processor is even dumber than I thought it was. Scumbria
