I’ve owned h50, h55, h100, h100i and a h100i v2. The only one that was close to this loud was the h100.
The h100i v2 was just taken out of the system for this cooler. I can tell you that you couldn’t hear the pc at all over room noise. I can hear this h150i as soon as I walk in the room.
I would love to see their testing where the pump is 20db. Corsair do you have a video of this?
