Sylvain G. 5 I was previously using an ENERMAX LIQMAX III ARGB 360mm, it was really noisy and my CPU went over 80°C in-game.I got sick of it and changed for the Dark Rock pro 4.Now idle temp is in about 32°C, while in-game is about 70°C max, 60°C for less demanding games. And it is MUCH more silent than the water cooler, I almost can't hear it.Love this product.
