    Hey guys. Sorry to start a new thread on this, but the relevant temp and t7500 threads my search turned up were old and closed.

    I recently ran a stress test on my CPU (with Orthos) just for s and giggles and found that my CPU temp maxed out @ 83C during the test. I ran the test for an hour and got zero errors and no crashing or issues, but it seemed a little high seeing as how I have a 120mm fan installed in my desk to keep my notebook cool. However I do have an HP docking station connected which is why I installed the fan because it connects right where the CPU and GPU are located generating a lot of heat.

    Just wondering if maybe my temp sensor might be off or if I might want to reapply the thermal paste. My specs are posted below. Thanks for any advice anyone can give.

    Notebook: HP CTO dv9000
    OS: Win7
    CPU: T7500
    GPU: Geforce 8600 GS
    RAM: 4GB DDR2
    Idle: 40C
    Stressed: 83C
    Room Temp: 78F
    Owned my notebook for about 2 1/2 years now

    Maybe I'm a bit desensitized to higher temps, but that doesn't really seem so bad.

    Those temps are perfectly normal. Your CPU is 35 watt, and my 25 watt CPU get's to 79C under full load.

    Ditto. Repasting might drop a few degrees, but it's a pain in the butt for what looks like a perfectly fine max temp. Even with a cooler running full bore, there's only so fast that heat can be wicked away, especially when you're trying to run at 100%

    Yeah those temps are fine. 100C is where they have to throttle down. You got a good buffer there.

    Definitely under volt though, improves batter life and reduces heat so why not. Throttlestop can even get you an extra 200MHZ in dual ida mode on some laptops.

    How long have you had the laptop though?
    It's also possible it's reaching those temps because of dust build-up.
    What you could try doing is pressing the vacuum cleaner to the air vents when the laptop is off, use a compressed air can, or open up the laptop and clean it manually.

    That said, I also recommend undervolting the cpu to reduce the overall temperatures.
    Re-pasting might be prudent (depending on how long you have the laptop).

    that's still a good temperature for your processor. try to undervolt some more.mine is an hp compaq with T7300 and my max temp is around 63C after undervolting. also try to check your temperature with your computer undocked.

    i just blow compressed air into my fans and undervolt CPU and use a notebook cooling pad... my CPU temps otherwise used to hit 90-100C in gaming but now 85C at most... but that's in india... in UK , its much lower..

    Thanks again for the advice. Since I don't game on my laptop, I never see my core temps go above 50C. It's usually between 38C and 48C (and that's with the docking station connected). I was just worried because I thought that under 100% load, the temps were supposed to be a lot lower. Now that I know 83C is in the ballpark for a stress test, my mind is at ease.

    However, now that you know what my usual core temps are on any given day, if you still feel that I should be undervolting or doing anything more than cleaning out the dust, please let me know so I can get to work :) Thanks.
