I use this build mainly for gaming.
I gave it a slight overclock: 6600K runs at 4400 MHz @ 1.270v 1070 Strix OC runs at 1955 MHz / 2110 MHz
This increased my FireStrike rating from 12.973 to 15.020. Cinebench R15 increased from 607 to 736.
After a torture test of 17 hours, using Prime95, the maximum temperature of my processor did not exceed 54 ºC / 129 ºF.
My GPU does not get warmer than 61 ºC / 142 ºF.
I might overclock a bit further in the future, but this is sufficient enough for now.
I am going to replace the two casefans with non-LED corsair ML fans.
