Black Heatsinks
Cools great
PWM Control
Very quiet even on full load
Rubber isolated mounts
Fits in my Corsair 300R Windowed Case
The mounting screws for the heatsink to the motherboard have a maximum tightness set. This prevents over tightening and possible damage as well as ensure the most efficient connectivity the CPU.

Idle: 80-85 °F
Load: 170 °F (AIDA64 Stability Test - 10 minutes)
The white border on the fans would look better in black.
The fans should really be PWM fans and not use a weird splitter to a PWM cable. This creates extra clutter in my system with more cables that also don't match being white in color.
The metal mounts for the fans (This could just be me) were quite difficult to get into the mounts onto the fans without bending them excessively.
The method used for screwing the heatsink to the motherboard isn't the greatest. It would be better if they reversed the design, instead of the male end of the screw on the motherboard mount put that on the mount on the heatsink and the female end on the motherboard mounting end. This would make it a lot easier to line up and screw in especially because this cooler is huge and there isn’t a lot of room in between the towers.
My G.Skill Ripjaw ram did not fit. The front fan would sit on the rams heatsinks and cause the side panel to not fit. After getting some low profile ram everything fit perfectly.
Also I did not use the massive amount of thermal paste included, I used Artic MX-4.
Has a LOT of cooling potential, high performance air cooling is a wonderful thing.
Mine arrived broken in two ways:
The top of the heatsink was damaged so the top panel would fall off. Also, the baseplate was slightly bent so I couldn't mount the cooler without fear of breaking my mobo (the mounting screws were too high to drop the plate). It seems to be quite fragile, so be careful.
I wish it had worked out, I had high hopes for it. Also note that you will have trouble with tall RAM.
