The temperature of the core is pulled from MSI Afterburner with the max reading used after a completed run of 3DMark Vantage at the Performance preset.
Under load, the MSI R9 280X 6GB Twin Frozr Gaming OC comes in at 75C. You can see this puts the card in the top half of the pack. Overall, though, the number isn't too bad considering the strong overclock we achieved on the card.
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).
While a little on the warm side, the noise levels on the card are fantastic. You can see we're sitting well into the bottom half of the pack. Considering the performance and the overclock, these numbers are really impressive.
