Hi Guys, I have here a HP ZD8000 (ZD8202AP) laptop. The processor is a Prescott Pentium 4 3.2Ghz LGA775, Processor Number 640. ( Intel Specs here http://processorfinder.intel.com/details.aspx?sSpec=SL7Z8 ) The computer has 3 fans on the underside, two spin always, the third one spins occasionally when it seems to go over about 65C. The heatsink and fans are all clean and free from dust. It is summer here but the ambient air temp is about 20C. I am worried that it is running too hot, and perhaps the CPU is getting throttled to keep temps down? HP Engineering said that 65C was not too hot to worry about and the CPU shutdown would occur at about 100C? The intel spec sheet says the Thermal Specification is 67.7 (about the same temp that the third fan kicks in at). So my question is: 1. Is it normal for a Laptop to be running at these temps under normal load (Internet Browsing) 2. If not, how can I make it run cooler???? Cheers -Al

The P4 is just a hotter running chip I think. I once swapped a celeron out of an old laptop for a faster P4 and the cpu temp spiked greatly. It was not uncommon to see it go to 73 at super max load. Idled hot like yours but never had any problems. Just the cpu I think. <BigAl.NZ@gmail.com> wrote in message news:dac80a74-0ada-455c-8a6e-1388226c02db@u72g2000hsf.googlegroups.com... > Hi Guys, > > I have here a HP ZD8000 (ZD8202AP) laptop. > > The processor is a Prescott Pentium 4 3.2Ghz LGA775, Processor Number > 640.

A laptop with a P4 in it was usually considered a "desktop replacement". Yousuf Khan

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. ID

Even worse were the cut-rate laptops that used regular desktop P4's.
