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.
Sitting at 72c during load, you can see that the heavily overclocked HIS IceQ R9 290X iPower Hybrid iTurbo 4GB scores perfectly in line with the MSI R9 290X Lightning.
While that card managed a slightly higher core clock, the memory clock was significantly lower. Looking at the idle, though, you can see our HIS card is sitting much lower.
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).
At 61.1dB, the noise level is significantly lower than the MSI Lightning, which sits towards the top of the pack at 67.6dB.
The idle noise number is also much more appealing, coming in nearly 9dB lower on the HIS offering.
