Just spotted this Guide @ our Good friends..... NFTS.org
The basic idea behind doing this is to make it so that when the CPU does not have any instructions to execute it should stop doing things completely, which in turn should cool it down. Ever wondered why the CPU is so hot even when it's just sitting there? Well, all modern CPUs (including Intel) has the ability to use two chipset settings known as HALT Command Detect and Disc When STPGNT# Detect. In the KT266/KT266A motherboards these registers are disabled by default. So all we have to do is enable them so the CPU will relax when its not required to do anything.
