PowerColor HD 7870 Myst Edition Testing:
Temperature testing will be accomplished by loading the video card to 100% using Unigine's Heaven Benchmark Version 3.0, with MSI's Afterburner overclocking utility for temperature monitoring. I will be using a resolution of 1920x1200 using 8xAA and a five-run sequence to run the test, ensuring that the maximum thermal threshold is reached. The fan speed will be left in the control of the driver package and video card's BIOS for the stock load test, with the fan moved to 100% to see the best possible cooling scenario for the overclocked load test. The idle test will involve a 20-minute cool-down, with the fan speeds left on automatic in the stock speed testing and bumped up to 100% when running overclocked.

- Temperature measured in degrees Celsius
The temperatures delivered by the PCS+ HD 7870 Myst Edition are acceptable in the grand scheme of things with temperatures never going over 70 °C. However as a non-stock solution it looks as though it is a bit on the small side when looking at the idle and load temperatures that are the highest in this comparison field of cards, at idle and under a load. Spooling up the fan to 100% helps bring the maximum temperature down to 61 °C when the card is overclocked but there is a noise penalty to pay. The fan used spins up to 3500RPM at a fan speed of 100% and can be heard clearly over other components in the case. When PWM controlled it rarely if ever reaches that threshold. It may be this reason that PowerColor locked down the ability to access voltage controls outside the PowerTune limits of +20%.
