Computer Generating Excessive Heat

[foodfightr]

I'm running an athalon amd 64 3000+ with two sata drives in raid 0. I have a geforce 6800 GT graphics card. All of this is plugged in to my Microstar K8t Neo-FSR motherboard. I have a case that is souped up with 5 neon fans and venting to keep the computer cooled. At night I have to shut down the PC to cool down the room, as it will heat the room up a couple of degrees when running. I understand a small raise in temperature might be expected, but this is beyond normal function.

How can I fix this problem?

Thank you very much!

Heh, you should see how hot my office gets with my mac dual G5 monstrousity!

Make sure your fans a blowing the right way, check the flow, maybe a fan is spiing the wrong way and just causing a hot air pocket or something.

run cool'n'quiet ?

Anyway welcome in the club...especially if you overclock (like me) and increase voltages and have a high-end card (like the X850XT)...well some days in summer i think twice whether i wanna play *at all* because of the heat.

(Live under the roof)

My sys is fine when idle (cool'n'quiet/rightmark cpu clock is installed)....all voltages are down as low as they go,,,,but once i start up w/ gaming etc. i get an incredible amount of heat and that's not cool if it's already like 80 or so in the room

1) Reduce your power consumption. Underclocking/volting the CPU (using Cool 'N Quiet, etc.) and/or GPU will help. Significantly overclocked/volted components can also be using 50% or more power than normal (which could be an extra 50-100W right there if you have OCed both the CPU and GPU).

You might also be better off with a 2-3 slower 120mm fans than five(!) 80mm ones. Fans with lights also draw more power (and thus generate more heat) than 'normal' fans, although this isn't a huge difference. It would certainly be a lot quieter.

2) Increase efficiency. Getting a high-efficiency PSU might reduce the overall heat output of your system by 50W or more.

anyway:

Check into "Cool'n'Quiet" maybe google around a bit how to install it....and then in your bios (if you dont overclock) check your chipset/cpu etc voltages....and check and report the temps you have on your CPU/Chipset...eg. with a tool like motherboard monitor etc. or check in bios what it says there.

CPU shouldnt really exceed 50 C (under load)...since you dont overclock i'd say should even be lower..like 40s with normal voltages.

I have a tool called rightmark cpu clock which allows to downclock when i am idle (similiar to cool'n'quiet) , when i am idle my CPU runs at 0.85V and 4x multi....which makes it barely 26C when idle. Under load (like gaming etc) rightmark switches up, multi goes to 11x and CPU gets 1.425 (+13%) which totals to 1.56V and i get max temps of 51C or so. X850 also exhausts an enormous amount of heat alone

i am running a A64 3500+ winchester with 11x237...and i am able to run my memory at 2.6V (which is pretty low)..always depends on memoery and how high you clock and what timings you use etc.

So to enable cool'n'quiet I just turn my power options to "Minimal Power Management" ? Will this affect my computers speed at all when I am actively using it?

no, thats the nice thing about it.

Only for benchmarking or similair you can turn it off.

With the rightmark cpu clock tool you have even more control - but it might be a bit complex to set up. You should be fine w/ CnQ.

only way to generate less heat is to get a more efficient psu. doesn't helpthat much

What's your monitor? My 19" CRT easily puts out the most heat in my room.

The couple hundred watts your computer puts out is not much more than a light bulb - get some ventilation in your room

A "couple hundred" watts is about 3-5 light bulbs (assuming you're talking 60W incandescent lights). That's a significant amount of heat in a small room.

CRT monitors certainly don't help, as they can put out ~100W by themselves (sometimes worse if they're really big and/or older models).
