Installation:

The first obvious step to take before installing the NC-U6 is removing the original cooler from the motherboard; here you can see the NB exposed.

Then the supplied space foam was installed onto the base of the NC-U6, this is a very important step to take because it prevents the chipset from being crushed due to uneven mounting.

After putting on the thermal paste (Artic Silver 5 was used) it was time for the mounting of the cooler, but here some problems arose. The way the hooks were aligned made it impossible to get them to attach onto the mounting clips of the Asus P5W DH motherboard.

Many motherboard manufacturers have all four mounting devices on their motherboards, but the P5W DH has only two. Upon contacting Noctua they were aware of the problem and had a workaround.

You will have to turn the hooks around simply by releasing the screws holding them down, switch them around and use the other side.

The right side of the mounting hooks is turned in this picture; I was a bit weary that due to the different angle of the hooks the pressure down on the heatsink wouldn’t be enough, but Noctua ensured me that the pressure would be sufficient and no loss in performance should be seen.

Here is the NC-U6 mounted with the reversed hooks.

And finally some shots with the product mounted and ready to perform. As can be seen in these pictures, if mounted in this way the NC-U6 basically is an active chipset cooler benefiting from the CPU coolers fan drawing air through its fins.
