Here is the test setup we used to test the G.Skill modules:

Motherboard ASUS Maximus 4 Gene-Z (Z68)
CPU Intel i7-2600K
PSU XFX 650W
SSD ADATA S599
GPU GTX 570
OS Windows 7 Fresh Install w/All Drivers

Here you can see that the fan really is nice and blue, the only downside is that it covers up a large part of the CPU heatsink area. We don't really know how you can fit an aftermarket cooler for the CPU on there without moving the fan to the side. Yet we do get a fair amount of airflow from the fan.

Here we can see that the cooler fits on the board very nicely. It is designed to just be dropped in without the use of a screw driver, and we really like that fact.
