I meant 100C not 100F, sorry about that. It's a Pentium M. I've checked the fan and heatsink and both appear to be working correctly and properly attached. I've blown out the vents as well. I can avoid overheating by throttling the cpu via hw.acpi.cpu.throttle_state but that gets really slow by the time the temps are below 75C. Joe
