Summary: Solid fan, Added this to my Noctua NH-D14 CPU cooler after removing the other 120mm that came with it. With matching 140mm fans on the cooler, it looks fantastic. Only thing to look out for is the size of your RAM DIMMS with this setup and how high the fans need to be mounted . Regarding the fan, it looks good, works good, and blows a ton of air through the cooler to keep temperatures down. Very Quiet. Noctua FTW, now a huge fan... Hehe.
Pros: - Solid Fan, - Quiet, - Looks are far better than expected
Cons: - Cost, but worth it to those that buy them.
