so the computer I just build, the graphics cards are overheating, and they don't have space for mounting fans, they are nvidea ge force 6200's and have been running at 140 degrees Fahrenheit since I got the sli working

Are the integrated fans working?

IF you are running windows, everest home edition can tell you some of the other temperatures and fan speeds.

Here is the guide I followed the first time I built my computer.

Does GeForce 6200 actually support SLI?

140 degrees fahrenheit (60 degrees Celsius) sounds quite normal to me. As long as it's stable, it should be fine.

Duh, I never even thought of that. Yes, 140F is a reasonable temperature.

My Radeon x1650 is 53 degrees Centigrade right now.

they dont have integrated fans, just heatsinks, I have a program called speed fan, but all my fans go directly into the power supply, and yes the 6200 supports sli anything with the same gpu can be SLIed

May be worth getting a better case that is designed to have extra fans installed.
Remember the lower fan at the front bottom needs to suck air in, and the air needs to exit at the top near the power supply. This is because cold air sinks and draws in colder air to run over the processor and through the expansion slots. Try not to have the computer in a place where it can't get sufficient air-flow. ie vents blocked or close to blocked

I actually added a vent and fan to the window on mine to blow on my GPUs. I changed out the plexiglass rather than damage my original.

Shouldn't that side fan be blowing the air out, not in?

I've tried it both ways: that way works better.

That fan should be internal and blowing/sucking air IN... 8)

General rule, lower spaces for fans are primarily for drawing in air, higher up they are, the more likely it is they should be throwing it out

Optical illusion aside; that fan is on the inside of the plexi. You can see the cut edge/surface of the plexi at the bottom of the fan. It draws air into the case.

I have a top mounted fan blowing air upwards; kitty liked to sleep on it. As well, the PSU fan blows out at the top. You can see a black 120mm fan excavating air out the back as welll; I have a surfeit of air being blown out of the case. What I lacked was air intake. That 120mm window fan replaced a 80mm vent at that location.

You will need a good circulation of air being drawn over the components for adequate cooling... I would opt for taking masses of cold air in over masses of hot air out. Cold air is denser after all, so there is more of it ;)

Keith, You are killing me! :)

Lets try this again.

Arrows indicate direction of air flow. Cool air from outside the case is blown directly on the twin graphics cards. I too opt for adding cool air in.

Can we agree that we agree? :)

I think it's better to suck air out. A negative pressure in the case gives better flow and a cooler case. Plus there's a risk of localised heat buildup when pushing more air in.
