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.
Temperatures are very healthy for the Sapphire Pulse, with edge temperature peaking at just 65C. Junction and memory results peaked at 87C and 72C respectively, which is absolutely fine for a card of this calibre.
Just confirming that, we didn't see hot spots on the card exceeding 61C using our thermal gun, so Sapphire has definitely produced the goods in terms of this card's operating temperatures.
