Temperatures were measured after 10 minutes of load under three scenarios: Furmark GPU stress test, Unigine Valley looping at the Extreme HD preset and desktop idle. GPU-Z was used to record the maximum temperature, fan profiles were left to their default behaviour.
Delta temperatures are presented below to account for small adjustments in room temperature, but for all the testing present in this graph the temperature ranged from 21.4 to 23.3 degrees Celsius.
Both PNY cards had similar temperatures, which makes sense given the cooling solution is identical. The PNY GTX 960 ran a little hotter due to its higher TDP and as a result the fan speeds were also a touch higher (1-3%~). The real-world temperatures for a room- temperature of around 22 degrees Celsius are between 60-70 under very high stress, and 40-45 at idle due to the passive fan mode.
