For temperature measurements I used furmark for 30 minutes under full load for my maximum temperature readings while the fan was left in auto mode. I then allowed the video card too cool down for 30 minutes for my idle temperatures. My ambient temperature hovers around the 68F degree mark, so please take into consideration when looking over this chart.
Looking at this chart we can see that the XFX R7 370 video card handles the heat output of this video card quite well. Even while using the auto feature of the fans on the heatsink. Which, is telling me that this video card is quite capable of handling long gaming sessions. Also it allows us some flexibility with our ambient temperatures of our gaming rooms.
