CPU Temp Gets Up To 90

by lilyput76 / October 26, 2008 4:31 PM PDT

This is driving me nuts. My laptop is a 2001 HP Pavilion. It started to overheat last year when I would play video games, so I purchase a cooling fan & a small fan to run behind it. It worked great up until I updated a System Device. I can't recall which one, but it added a bunch of new items that begin with ACPI. Since then, my computer gets really hot even with the additional fans running. I researched online & figured it might be my thermal heatsink.

I downloaded a program to show me how hot my CPU gets & on idle, it was at around 53

How long have you got that laptop, that's hot indeed, maybe you need to clean it, there is something wrong with the fan. Or have you tired a laptop cooler for it?

I've had the laptop since 2002 & purchased a cooler & an small table fan last year when it started overheating. When I opened up the laptop to apply the thermal compound, I cleaned out the fans, too. Do you think I should replace the fans?

you've either lost speedstep or a fan is going bad

Here are the specs:
*HP Pavilion ze4800 (though, when I update on HP's site it says I have a Compaq Presario 2100)
*2.12GHz/508MHz Athlon XP2800+
*Radeon IGP 320M (found out that AMD has forgotten about this processor, so no updates since)
*512MB of RAM
*55.8GB Hard Drive

Not sure what speedstep is, but if has altered my fan speed, how do I fix this?

Should I try replacing the fan?

download and install AMD processor driver from this page. it will add/enable any missing CPU power management features. also download and install the GART driver from this page.

All my drivers are up-to-date. I did a driver update as soon as it started overheating. I'm hesitant to download anymore suggest software (I've download 5-6 suggested programs so far) to help solve my problem. If it comes down to it, I'll check out that page.

those drivers i linked to are straight from AMD

they could fix your problem. if your drivers are indeed up-to-date, you have nothing to lose since you'll just be reinstalling the same drivers and reinstalling often fixes problems.

Thanks for the suggestion. I think you misunderstood. I already have the updated drivers installed, downloaded from AMD a few weeks ago, before I posted this thread.

I resolved the overheating problem. My fan was failing - not spinning smoothly. The fan has been replaced & all is well now.

Thank you again for your help! I appreciate it!

let's get to work.

First the memory is right on. Some is used for the video display. Don't spend much time on that.

I missed what OS is running but I'm going with XP.

-> At this age if it was my machine I'd do the usual teardown, clean off the fans, the old heatsink compound, put on fresh heatsink compound and button up the clean machine.

Now that it's all back together I would install SPEEDSWITCHXP and try it at the lower CPU speeds and see if that helps.

I did the teardown, dusting, & replaced the heatsink compound before making original post. The CPU temp went from 53 degress on idle to around 35 degrees. It's much cooler on idle, but the temperature hikes way up when I run something like disk cleanup.

I have something similar to speedswitchxp which lowers CPU speeds, but it slows down my computer a lot. Maybe I'll uninstall that program & replace it with speedswitchxp. I'll let you know how it goes.

reset the system and the RAM question
by PcTestCard / October 27, 2008 6:08 PM PDT
In reply to: CPU Temp Gets Up To 90

Hi,

The Ram shows only 448 because you allocated total 64mb to video. your laptop came with onboard VGA card.
512 - 64mb RAM for video display = 448MB RAM for system.

In order to discharge and reset the whole laptop, please remove all removable devices such as external KB/Mouse, PC cards or DVD drive( if removable) and take the battery and the Ac adapter away from the laptop.
Then pressing down the power button over 15 seconds and press a few times after that, this will reset the laptop and discharge the static on the laptop.

Then, ONLY connecting the AC adapter to the laptop and power on the laptop and reset the BIOS.

By doing this is to make sure there is no system conflict and the CPU is not doing extra works.

Also check the network and HDD activitiy, make sure there is not application keeping the HDD and network loading and thus heat up the CPU.

Hope this helps!
Bill

Thanks for the suggestion. I followed your instructions to reset my system. Everything seems the same, though. On idle, it's cool (around 35 degrees C), but when loading or running programs, it gets up to 80-90C.

Someone suggested the fan needs replacing. I have a spare fan & can replace it, if that's the case.

While I was in the middle of adding heatsink compound to the new fan (the heatsink is attached to the fan, in my case), I noticed how easily the new fan spun when you blew on it. So, I thought to see if the old fan spun as easily. I blew on the old fan & it didn't spin at all.

I think we've solved the problem. Now, the temps are around 43

Sure the temp readings are accurate ?

Suggest trying PCWizard 2008

http://www.cpuid.com/pcwizard.php

Among the many many things it does, it can report real time temps that are visible on screen when you check the 'Processor' icon and minimize the program.

Adding more RAM would definitely improve performance...won't help the temp issue. Exactly what model HP Pavilion notebook is that ?

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
