Sapphire Radeon HD 5970 2GB Overclocked - Temperature and Sound Tests

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.




With the voltage and clock speeds bumped up, the temps seem to also rise slightly. It's nothing to worry about, though.


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).




As the cores have warmed up the HD 5970 has taken it upon itself to increase the fan speed to help keep the card cooler. In turn, that's increased the noise levels under load.
