I have a NZXT S340 Elite Case, with 2 exhaust fans 120mm Bequiet! SIlver wings 2 (I know I should replace the top one for a 140mm will do in the future). I'm using a Kraken x61 too cool my I7 6700k. So far my issue is that recently my 1080 is hitting 85-86C temperatures and it didn't do that before max load was 71-73C. my room temperature is 77-80 Fahrenheit . My cpu is 34-36C idle and so is my 1080 atm the moment. I created a fan curve with MSI afterburner. I also change back the core voltage to its default. While gaming FFXIV the game crash twice and I saw the temperature of my 1080 hit 86C. I updated the drivers, and created the fan curve. I've check my case by touching the glass, the back panel and under the case and there is no heat. The case is quite cool and a little warm on the glass panel compare to the rest of the case. Hope somebody can give me a few pointers. Will test to see if the issue is resolved with the changes I've made.
