With the TES 1326 Infrared Thermometer literally in hand, we found ourselves getting real-world temperatures from the products we test at load (3D clock speeds).
There are two places we pull temperatures from - the back of the card directly behind the core, and if the card is dual slot with an exhaust point we also pull a temperature from there, as shown in the picture.
We see that the GTX is quite warm behind the core, while the exhaust temperature is significantly lower than the ATI HD 2900 XT.
Pulling out the TES 1350A Sound Level Meter we find ourselves quickly yelling into the top of it to see how loud we can be.
After five minutes of that we get a bit more serious and place the device two CM away from the fan on the card to find the maximum noise level when idle (2D mode), and under load (3D mode).
The GTX continues to be one of the quietest high-end cards on the market and the overclocked Zotac is no different of course, since it uses the same cooling setup.
