1080 SLI EKWB high temps

hi i just build my first custom loop. i got 2 EVGA 1080 SC cards

my gpu's i getting pretty hot.. double checked everything when i mounted the blocks idle temps are about 30c when under gaming load they max out at 50c sometimes mostly they are in the 48 range

don't know if it good temps or bad temps just reading on forums that there cards only reach about 43

based on what i have seen on reviews.

the cpu is part of the loop. got a EKWB 240 PE and a 360 EKWB PE radiator

so my question is? is it ok temps or ? '); }
