I am using the EVGA hybrid Cooler on my TX and have heatsinks on the Vram and vrm on backside. My gaming temps are around 43-45C.
I have used modded bios and really pushed it, at times, and although I need to put the fan up to 85% my benching runs don't get above 50C on the core. I have checked the back with Infra-red temp gun and hottest area I find is 77C.
I should really go custom water cooling but I change stuff quite often and the hassle always puts me off.
Just re-ran some benchmarks after upgrading to Win 10 and reached 20th on FireStrike Ultra Hall of Fame
with score of 5480. TX was at 1547 memory 8208 (2052).
Was able on Win 8 and older drivers to get core a bit higher, but for a TX with its more limited voltage systems compared to the custom 980Ti's I am very pleased
Was going to get a Fury X for my other rig but the whining problem is really putting me off. That 980Ti HOF is now tempting me.
