overheating laptop when running cpu emulator

My laptop (HP nc8000) overheats (85-100F) when running cpu simulators like bochs
and simulavr.  I guess this is a hardware problem but wanted to rule
out any misconfigurations on my part or software issues that may be
related.  The laptop doesn't overheat during buildworlds though this
isn't a constant CPU workout either.  Included is a copy of
/var/run/dmesg.boot and my kernel config file.
