For our temperature testing, we measure the peak GPU core temperature under load, as well as the GPU temperature with the card idling on the desktop. A reading under load comes from running the 3DMark Fire Strike Ultra stress test for 30 minutes. An idle reading comes after leaving the system on the Windows desktop for 30 minutes.
With a peak operating temperature of 67C on the GPU core, PNY's cooling solution is certainly effective. This marks an 8C reduction in temperature versus the Founders Edition, which allows the core to run about 60MHz faster under load.
There's nothing to worry about in regards to the thermal camera images, with hotspots around 59C on both the front and back of the card.
