Nice! Those temps are excellent. I have been running just with the stock cooler and the results are pretty solid. About 30% improvement over my Fury X.
However, the Time Spy stress test isn't all that stable with Vega 64 and the stock cooler. I imagine liquid cooling would be a huge help there.
Absolutely. I haven't had a single crash in Time Spy (sans when I pushed the core or mem too far). I had a marathon gaming session for about 6 hours last night and temp got up to about 50c. Not bad at all.
Sounds rock solid. What scores are you seeing in the Time Spy stress test? I was getting well over 99% on the Fury X, but the stock Vega 64 is giving me 97.6%. While still passing, there is clearly a lot of flux with the clock speeds as the GPU heats up.
