CPU + GeForce GTX 1080 MSI Gaming X cooling benchmarks
Core i7 4790K and GeForce GTX 1080 MSI Gaming X performance benchmarks
So we have now added the GeForce GTX 1080 MSI Gaming X to our liquid cooling loop. Quick stress tests show that the 1080 really digs the cool temperature as it remains at a very steady clock frequency - it remains hovering rock steady at the 2000 MHz marker (without throttling). For this test we are doing things a little differently, where we used wPrime for the sole CPU stress test, for both CPU and GPU we feel it is better to mimic an intense gaming session. We use a custom 3DMark FireStrike (Performance mode) and select and specifically loop the "combined" testing mode. This mode will put good stress on the processor, and maximize stress on the graphics card. We then leave it to simmer for 15 minutes to half an hour in total.

Above, CPU @ default / GeForce GTX 1080 MSI Gaming X GPU @ default:
- CPU load temp is 66 Degrees C (max)
- GPU load temp is 51~52 Degrees C (max)
CPU @ 4600 MHz - 1.30V voltage / GeForce GTX 1080 MSI Gaming X GPU @ default:
- CPU load temp is 71 Degrees C (max)
- GPU load temp is 51 Degrees C (max)
Let's up the ante a notch more - CPU @ 4600 MHz - 1.35V voltage / GeForce GTX 1080 MSI Gaming X GPU @ 2050 MHz Boost / Volt +100% / Power limiter maxed out.
- CPU load temp is 75 Degrees C (max)
- GPU load temp is 51 Degrees C (max)
I have yet to find a Core i7 4790K that actually needs 1.35 Volts, but the Predator 280 runs it reasonably enough. The GTX 1080 then, we overclocked it to 2050 MHz (Boost). The card has added voltage and a higher power limiter allowance to go higher.
With the 1.35V Core i7 4790K at 4600 MHz, the GPU overclocked at 2050 MHz stable (and constant on that clock) shows a working temperature of 51 Degrees C. We measured at an ambient room temperature of 21 Degrees C, our looped stress test runs roughly half an hour.
