I do all testing on my standard test bench with a 7700k running at 5.0 GHz. I keep the ambient temperature at 21°c, or about 70°f. To get idle temps, I let the PC idle for no less than 30 minutes before recording the idle temps. This give a more accurate result. Each benchmark is run 3 times each, for 120 seconds. I then average out the three runs. Each game is tested in 1080p, 1440p, 4k and 3440 x 1440 resolutions. I do repeat the same section or level for each benchmark and I do not use in game benchmarks. All benchmarks were run on air, in OC Mode in GPU Tweak II. 3DMARK and Heaven were also tested in SLI and temperatures were recorded on air and water. Gaming results were run on air as well.

Being a hybrid card, it only made sense to test the card on water as well as air. I didn’t use a custom loop. However, if I had, my guess is the temps would have been even lower. Instead, I hooked the card up to a modified Swiftech H140-X. It a 140 mm AIO, or all in one cooler. I replaced the barb fittings on the cooler with compression fittings and put a swivel fitting on one as well. On air, the GPU hit a max temperature of 76°c and idled at 55°c. When I added the AIO cooler, my idle temps dropped by 15°c to 40°c. The GPU temp maxed out at 63° at the end of testing.
