Hi on about 25 degree day, my idle coolant temps are roughly 33 degrees and that fine because i run them at a low rpm, but when gaming with a 3080 ti and 5800x it can sky rocket into the mid 40s with the fan running about 1800 rpm. with my case i can only top mount it with it exhausting the heat out. My question is the normal behavior because my gpu is dumping over 300-370 watts of heat onto the radiator.
I upgraded from the h100i plat because i thought it would provide lower noise but it seems it louder now because of the 3 fans but keep the temps of the cpu a little lower not sure it was worth upgrading to it.
