The TMp counts down from the maximum, so it is essentially a negative number. But nobody told the Intel BIOS programmers. They treat TMp as a positive number like any absolute temperature. As a result, the processor fan is throttled in reverse. WHEN THE CHIP GETS HOTTER, THE FAN TURNS SLOWER. This is a recipe for thermal runaway. There is a Workaround if you have extreme load or high ambient temperature: Cut the throttle wire to the fan (#4 on the connector, the blue wire on Intel fans that come with the processors. It can be restored later with a butt splice if necessary). Then the fan runs at constant full speed of 2600 RPM instead of 850 at room temperature, giving TMp of 52c instead of 40c, as good as an expensive aftermarket cooler, many of which use this trick. This fan is deep inside the chassis, so it can barely be heard. Otherwise, this board excells."</p></blockquote><p></p>
