I have the h440 with a i7 4790k and a gtx 970 strix, stock cooling on the case and a dark rock pro 3 on the cpu. It is dead silent, but both the gpu fans and the psu ones dont kick in unless needed and with a decent setup on the cpu fans it is quite and cool. 30-31 celcious cpu idle 60-65 while gaming (witcher 3 ultra 1080p), about the room temp it is summer here in greece, running at stock speeds and the gpu has a min 32 and a max of 72 running at 1400mhz (boosts to 1475) and 7090 memory no extra voltage applied
