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.
When it comes to the temperature side of things, it comes as no surprise that this is quite a warm running setup. With the extra voltage, the increased clocks, and the top card having to deal with the heat coming from the back of the second card, the whole setup is going to run hotter.
Overall, though, the 83C load temperature on the hotter card isn't too bad; especially when you consider the performance.
Pulling out the TES 1350A Sound Level Meter, we quickly find ourselves 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).
Noise levels on the card sit in the top half of the graph, but overall, they aren't too bad. You can see we're at a similar noise level to the heavily overclocked R9 290X 4GB Vapor-X from Sapphire.
