I'm using ATI tool and......

It's saying my temp is 74 degrees C. Is that normal? Too hot? Can I go higher?

Is this reliable? I have an ass load of fans in my comp....fairly large ones at that, just FYI.

A large quantity of fans can't overcome poor airflow or fluid dynamics.

If, for example, you have more in-flow fans than you have exhaust fans, that can cause turbulence that will reduce the efficiency of the airflow.

Evaluate your situation based on the CFM in and CFM out and try to figure out if your computer case has negative or positive air pressure and then try to simplify it.

I have 1 120mm front intake, 1 120mm rear exhaust, a low profile 92mm side intake which pushes room-temp air over my video card and the video card has a cooler on it that blows its own hit air out the back of the case.

Also, there is some exhaust from the power supply.

The easiest thing to do is to make sure all the fans are blowing the direction they should be blowing.

Here's a couple simple diagrams to follow.

it's completely normal for your GPU to get to 70 or even 80C.

Well, there's that too.

But all that stuff I said about air is true! :P

Ok, i messed around the with clock speed and the temp went up to 74 degrees and the number was in red, so i wasnt sure if it was safe or not

even if you didn't mess with the clock speed, the number would still be in red, and still be in the 70's...at least on a normal computer.

what you should do is let the cube spin for at least 30-60 seconds. go into the settings, and change the temperature monitoring time update to every 1 second. Then, watch the temperature graph as the cube is spinning. See where it starts off (baseline), and then where it levels out. Your true max will take a few hours to reach, but it won't be more than a few degress off of where it flattens out after 60 seconds of cube spinning action.

If your CPU/GPU/system was in trouble, 99% of the time it's going to shut itself off, or even power off, before it lets you hurt it. unless of course you've been fucking with the default auto shutoffs.

GPU's get insanely hot, that's just how they be (*Dr Evil pinkie* several hundred Meeelllion transistors).

The thermoprobe in the chip that ATIT reads isn't really accurate, it's about +20C too hot for true temperature.

And anyway, all modern processors have safety thermistors that shunt the power out of the chip if the temperature gets too high (you'll know when this happens; everything suddenly freezes because the processor stopped mid-instruction).
