Ron, see "Thermal Issues" here: http://www.lesswatts.org/projects/acpi/debug.php My guess is that ACPI (and thus Linux) have no control over the fans on this system (as I've never seen a Dell with OS controlled fans) If the fans are spinning fast when you heat up the machine, then they are probably clogged with dust or there a mechanical issue with the thermal solution. cheers, -Len
