4K 60 FPS, Temps

[DoYouMerica]

Just Trying to Figure out if my rig is set up well enough for 4k 60 fps or am I running it to hard

Specs 

Alienware Aurora R5

CPU- i7-6700 non K

GPU- Evga 1080 ti SC 2

HDD/SSD- 1 TB Seagate and 1 WD TB and PNY 240 GB SSD

PSU -850W plus bronze

RAM- 1 Stick 16 GB ballistic

also I'm worried about my temps Under load my CPU sits right around 75c and my GPU is about 70c should I look for a better cooling option. and if so does anybody know a good option that fits in such a small case.

Those temps are fine. 

For newer games 4k 60fps ultra isn't doable on a gtx 1080ti, but if you turn the settings down to high you can do 60fps.
