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.
Looking at the temperature numbers, it comes as no surprise that the Sapphire R9 280 Dual-X 3GB OC sits towards the bottom of the pack. Sapphire has always done a good job with cooling, and looking above, you can see this is no different.
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 centimeters 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 best thing is that the great temperature numbers aren't coming at the cost of huge noise levels. Looking above, you can see the numbers sit towards the bottom of the pack, which is exactly where you want to be in a test like this.
