For anyone that might be running a little hot, it might be worthwhile to check the water cooler/ reapply thermal paste. i was running around 84 degrees on Die 1 and just reapplied thermal paste and reseat the water cooler head. Running about 8 degrees cooler now. Disclaimer, dont do it if you  don't know what you are doing.
