What is the real temperature?

dokkktor · Post by **dokkktor** » Mon Mar 03, 2003 11:21 am

Motherboard monitor has a CPU temp as 73 C
Sisoft Sandra has it at 36.6 C
The Bios has it around 55 C

Which one is correct?

I am getting concerned about the temp, it is starting to act a bit funny.

Seems to be a lot of heat coming off of the case.

I have a 1.2 Athlon with retail HSF.

I want to know before I upgrade the CPU cooling.

Any thoughts as to the best all-around?
Not overclocking, must be quiet, must fit in the case, etc...

Or is it my Powersupply?
I am pretty sure that my system is under powered, so could it be working to hard, hence the source of the heat?

Any thought let me know.

I want to know which I should do first, CPU cooler or better power supply.

Thanks

well, dont run any software after bootup for like a half an hour and see if the temps are any different. then you can see if the temps are about the same.

Open the case and maybe take a can of air and blow out the heatsink (and around it) and also blow out all your fans and Power Suply.

Usually the bios will give a correct temp, MBM needs to have the correct sensor chosen to give the right temps, and sometimes this needs to be calibrated. Also, there are several different temps given, sure you are looking at the correct ones? Also, check temps after a totally cold startup, in Bios, then run it under load for a half hour, reboot and check bios again for difference.

What Greg said about dust and dirt, a clogged up system will really heat up, give it a good blow job

With the bios temp it will rise the longer i leave the computer on. - just leave it at the bios setup.

The MBM are the right sensors since I cross-reffed them with the amd site like it says in the set-up.
the problem I have is that the reccommended temp limit is 70 C and sometimes the sensors are reading over that. - How concerned should I really be?

If your power supply is overworked (ie-not large enough for the computer) will it cause that big of a heat change?
Will going with a bigger power supply result in one that runs cooler (ie-underworked), or is it more important that it is a very good power supply with dual fans & such.

I have been looking for these answers for awhile but have no idea where to look. If anyone has some links to power supply & heat related issues let me know.

Thanks.

Tell us your computer specs, what all is in it, type of case, fans, etc................

I would remount your heatsink, check thermal paste, close it up and check temps. Then pull off the side cover and put a big window type fan next to it, and blow air into it, see if the temps come down. If they do come down a lot, you need to improve case air movement considerably more. Something is definitely not right about your temps, the retail heat sink is not all that great. You should consider getting a better one if you want cooler temps.

Get one that mounts an 80mm fan, will be much quieter than a high speed 60mm and cool as well or better.
