I'm running i5-6500 w/ rx480, 8gb ram both system and card. 3 monitors, 2x27" 1920x1080 and a center 34" 2560x1080 where the game runs. Small raidmax atomic itx case, known to run a bit hot. My question is why the hanger, which should have a much lower compute toll on both the cpu and gpu, runs the hardware as hard, or harder, than matches themselves do. If I can successfully get in matches, within a reasonable amount of time, I can play for several hours. If I'm in matchmaking for long periods of time (i.e. in the hanger) the fans quickly go to full bore and the case gets hot to the touch.
If anything, the fans seem to be slightly less stressed coming out of a match, as opposed to when the match starts.
