You know, the fan seems nearly useless in the Lombard, as I have yet to see mine turn on at all myself. The fact that your OC seems stable at 433 at full load without the fan seems to suggest that the fan is wasted tech for those in temperate regions, or tweaked so that it turns on at far too high temperatures. I hope somebody knows a little more about the fan than I do.

Does anyone know what the determining factors are for the cooling fan in a Lombard to run? What controls it? How to test it?

The reason I'm asking is that my Lombard 333 (O/C'd to 433) with 512 MB running X.3.2 has been running at 100% CPU and heavy disk and CD activity for about an hour now and the fan has yet to come on even for a second. I lifted out the keyboard and the heat sink is uncomfortable to touch, especially over the CPU. I realize that this suggests that the heat is being removed from the CPU, hopefully effectively, but I'm concerned that it is getting too warm.

Now that I've had the keyboard open for a few minutes while writing this (I have an external keyboard connected), the heat sink is noticeably cooler. This really makes me wonder if my fan should be running...

Thanks
Dave
