Temperature Tests
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 temperature from - the back of the card directly behind the core and if the card is dual slot and has an exhaust point we also pull a temperate from there, as seen in the picture.
One of our HD 4870 X2 cores got quite toasty, but the rest sat around a pretty standard temperature.
Sound Tests
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 of the card when idle (2D mode) and in load (3D mode).
The long cooler does manage to crank out some decent dBs with it coming in at a similar noise level to the 9800 GTX.
