I have a very hard time believing that Techpowerup review is accurate!
No way @ 4K it hits 65C under full load water is only 45-55C ish triple slot fan low profile HSF is not all that temps wise.
According to them idle is 50C yet full load is only 65C again a fantasy figure for a flimsy air HSF!
Were these values taken in or out the case how many case fans etc etc
Looking closely at the review it looks like these values were taken @ 1920x1080 they are very similar to the results I got with my MSI 6G & stock HSF (55-57C idle & 65-67C under full load @ 1920x1080 even with not the worlds best case cooling according to some posters on here ).
That card needs to be tested @ 4K for the thermal values to have context/meaning any GTX 980 Ti gives similar values @ 1920x1080 its well within the comfort zone for the GPU even the stock HSF models give similar results!
Seems about in line with my strix at 4k temps wise.
