Plz forgive the poor computer skills :)

Anyways, my comp has four fans to my knowledge. There are two that are spinning in the back part of the case (and have the little grates so air can get thru drilled in case) There is one fan in the form of a big black cube like thing over my CPU, and another in the power supply. Theres also what I assume is a heatsink on my mother board.. its like this 1.5 by 1.5 inch square that is composed of a bunch of evenly spaced one inch straight pole things sticking up like this | | | | |

My comp (both my ASUS Probe 2 settings and my BIOS settings) both say my CPU is at around 60-65 degrees (around 143 Farenheit) after being on for a bit (without running any games or anything) A couple of times lately it wouldnt let me boot up because of something to do with hardware monitor... so I went to the BIOS, then to Power and hardware monitor and CPU temperature was flashing red 75 degrees. Ouch.

My motherboard is always around 30 degrees/86 F or half of whatever my CPU temperature is.

Anyways, i know my CPU temp is too high (people I know have it at like 40-45 tops), but it never reached this high before, probably because its getting hotter now in the summer.

My BIOS and my ASUS Probe 2 program both give me a reading of around 7600 RPM for my CPU fan... but they dont give me a reading for my power supply fan, and they dont have anything for chassis fan either (are those two fans at the back wall of my case the chassis fans??) But I checked and all of them are spinning..

Also, whats voltage? Its in my BIOS but in my Asus Probe 2 it says that one of them is threshold. There are 4 voltage settings: Vcore, 3.3, 5V, and 12V. All of them are bellow their names (ie, the 3.3 V one is at 3.152 V) but the 12V value is 13.376.. and is flashing. What does that mean?

And finally, inside my case I noticed that theres a sticker on my power supply that says like "Designed for the Pentium 4® Processor" does that mean anything? I have an AMD 2200 1.7 ghz CPU, 512 DDR ram and a GF TI 4400.

what HSF are you using?

the voltage is referring to the rails on the PSU. the 12V shouldnt be that high.
usually, p4 PSUs are fine for amd, what model PSU is it?

whats a HSF? Heat sink fan?

I dont know my PSU model.. do you mean the serial numbers or whatever on the power supply unit?

What you need is some decent air circulation in your case. Optimal airflow ist that cold air gets sucked in from the front-bottom by a fan, flows over PCI and AGP cards, the cpu and is expelled upper-rear by a fan or the PSU. From the sounds of it all those two fans in the rear (I assume they are blowing out) are just creating low pressure inside the case. Most cases dont have good venting in the front and the fan "holes" typically leave alot to be desired and that would be the largest factor to your "heatware".

I would first try moving one of the two aft fans to the lower front and try to get as good an airflow as possible. If that doesn't work you may want to contemplate breaking ot the dremel :D (if you do, don't forget to remove ALL electric components from the case: metall shavings and electric circuitry don't mix).

shady06: Looked inside, my heatsink has no fan.
The sticker on the PSU says P4300W

thraxes: there are no air holes/vents at the front of my case.. and its pretty conjested at the front of the case.. with my harddrive(?), zip drive, cdrom and cdrw. Thats also wheres theres a piece of plastic with the reset and power buttons are.

AMD Athlon XP 2100+

The heatsink structure itself is on the motherboard.. I cant even see my processor, Its under a fan I think (around 2.5 x 2.5 inches)
