Worthwhile Accessory
I picked this up to add to my NH-U12S Redux air cooler. It will only drop temperatures a few degrees more, but I had room for it in my case so wanted to add it.As you would expect from Noctua, it arrives in a nice box and comes with a fan splitter cable, two low noise adapters and the metal grips to attach the fan to the cooler.The fan fits perfectly and isn't too loud either. Recommended.

Great addition.
So impressed with the quietness of NH-U12S redux Cooler I added this upgrade to ensure a well cooled CPU which had a reputation of running a tad warm. The result is really impressive with a really cool CPU and super quiet installation.

Very Quiet
Fiddly to fit but that's mainly due to the size of my case.Very quiet in use and the temperature have dropped by 5c there about.

Increases cpu cooling capabilitys
Fits perfectly as a second fan on the cooler. No complaints good for moderate over clocking
