System Overheating

By yiotie ·
Hi
I have just built a PC with the following spec.
Mainboard : GA 8ST600 (SIS 645DX)
Cel 1.7GHz
256MB DDR
30HDD
GeForce4 MX440 64MB, VGA
Win ME
The problem is the temperature.
The CPU temperature is OK at 35-40C, but the system temperature goes up to 65-70C. with just surfing the net, if I play games I do not last long, before I have to switch the PC off. (easytune gives the temperature, I have checked the BIOS too)
I also have added a heat extractor fun, but no improvement.
Anyideas please?
Thanks
Yiotie

Did you overclocked your processor ?

Check voltage (motherboard doc), replace processor heat extractor. Add good thermal joint between processor and heat extractor.

Do you have a good case for pulling the air out and relieving the temps that way? Multiple case fans? You could also try a card slot fan blowing on your video card. Good Luck

With the specs provided I'm going to guess inacequate case ventilation. Check to be sure your case fan is running properly and that your airflow isn't being blocked up by your IDE cables and stuff like that.

If you're leaving your case open this will cause the motherboard to overheat because you've disrupted the flow through vent and heat builds. If this is not the case then you need fans to suck the air in the front and push it out the back.
If none of this is working then you'll need a powerful cooling fan, which are available at http://www.coolfans.com/

If your CPU fan is properly sized and running properly, you most likely need to add air intake fans.

You want to force at least 10% more air into the case then the exhaust fans **** out.

That way, you do not starve the fans, and cause stagnantair inside the case.

I also fully agree with the answer that said to check your CPU core voltage setting.
If the core voltage is too high, or the voltage regulator is not working properly, it can cause serious over-heating and damage to the CPU.
