I have a ZD8000 with a 540 P4, the same specs as yours, but without
the 64 bit extensions. When idle the CPU temp is 50*C, except when
the 3rd (louder) fan kicks in, then it drops to 45*C. When running
Flight Simulator X, which has to be the most CPU intensive program
going, both HT cores are at a constant 100% utilization, and the CPU
temp stays constant at 61*C with the 3rd fan running continuously.
When I exit FSX the CPU temp drops back to 45*C in about 20 seconds.
I have a Seagate 120 GB 5400 rpm drive which runs at around 30*C
after the laptop has been on for a while.
Do you have it up to date with all the latest HP BIOS and driver service
packs? Some of the BIOS upgrades along the way have addressed
temperature control, and battery management issues. Also, when
running on AC power, removing the battery will lower case temps,
and extend the battery life. Also, raising the back of the case to give
freer airflow to the fans helps. Oh, my BIOS version is F.34.
