Computer heat problem

I've got a 1.4 Palomino runnng at 150mhz FSB (1.6) using one of these Speeze hsf's. It runs SETI 24x7 and the load temp is 41C using AS3. My wife's 1800+ is running at 1.6GHz and runs SETI 24x7 and the load temp is 43C. I've found these dudes will pull just about as much heat from a CPU as a Thermalright AX-7 for a small amount of money.

The clips can be a bit awkward, but I actually like them now that I know what to expect.
