I would also like to note that the pump for the H150i PRO is silent in both quiet and balanced modes

This is overkill for my i7-7700k (only mildly overclocked, all cores synced), but I love the fact that I can have it on silent mode and the fans don't even spin most of the time.

Running it on Quiet mode and hitting about 38 C idle on one core and about 33 C on all other cores w/ a 5930K @ 4.4 GHz and 1.328 Volts.

Balanced mode is somewhat audible but not at all bothersome

The pump is also completely silent on quiet mode

It's not a huge case and I got it to allow for the option of a "silent" mode when needed

When I then put my pump into "Balanced" mode, it went from 1080 rpms up to 2150 rpms and the temperatures immediately started to drop

ANY mention that the pump is initially set to "Quiet" mode, or how to change the pump speed, or how to setup the H100i Pro with iCue !!

The pump noise NEVER went away unless it was set to quiet mode.

Very quiet,CPU is running at 14 degree in Corsair link "Quiet mode"

Out of the box, it did a very adequate job of cooling the CPU running at stock speeds in "Balanced" mode, even when stress testing with OCCT and P95 (never got above low 70s even with the smallest sizes).

It is a great cooler and is all but silent on quiet mode
