are my i7 6700k watercooling temps normal ?

Recently made my first custom loop and expected better cooling than i am achieving
Build details: i7 6700k stock clock (atm)
waterblock: EK supremacy evo (did not change insert)
Radiator: Ek coolstreem pe 360 (pull, with EK vardar f3-120 (1800rpm) top mounted exhaust
pump/res: EK-XRES 100 DDC MX 3.1 PWM
current gpu : rx 480 (air cooled) (waiting for 1080ti)
case: corsair graphite 780t

temps: Ambient ~ 15c
idle ~ 16-17c
100% load(aida 64) fans at 20% ~44-45c
100% load fans at 100% ~ 42c

Did i set my expectations too High? or is this normal for the loop i have ?
And can i put a gpu in the same loop considering ambients approach 40c in summer or should i add a second rad? (have a second rad thats not in but requires me to remove 5.25inch bays where hdd is currently mounted, maybe move hdd ontop of the psu?)
 
Solution
Those temperatures are excellent and your loop is working fine.

Ideal temps are 10-15C above ambient at idle and 60-65C under load.

Plenty of headroom left for a decent OC.

Had it clocked to 4.6 at 1.345v on my msi z170a sli plus mobo, reached about 52c under load.
What would be a safe max voltage without effecting my cpu's lifespan?
 
The average voltage required at 4.6GHz should be around 1.35v, plus or minus a variation of .03v or so depending on how good your chip is.
If you find you need upwards of 1.4v to run at 4.6GHz, then you didn't get a very good overclocking chip and need to dial it down to 4.5GHz or even 4.4GHz.

The max long term voltage recommended to not exceed on a Skylake is 1.35v, although some are okay with up to 1.40v as 7x24 use (I would not recommend that). Intel says the max "safe" voltage is up to 1.45v. But on a 14nm chip, I wouldn't even come close to wanting to testing that without a serious liquid cooling system, as heat becomes exponentially a larger problem on thinner silicon and more voltage.

Heat is what effects the CPU for longevity as long as you don't exceed the recommended Core voltage, you will be OK.
