Noctua NH-U9S Air CPU Cooler Review
 

Noctua always made a very good impression- from build quality to installation and even performance. NH-U9S makes the same impression as one would expect. Quality that a lot of users appreciates. I've said it before and will say it again. Even though Noctua CPU coolers hold a certain premium- from the CPU brackets and screws, down to the quality of finishing of the heatbase and even detailed TDP/Motherboard compatibility list, they always give the money's worth. Oh yeah, they're probably the only ones out there giving 6 years warranty period and premium retail fan(s) and an NT-H1 thermal paste pre-bundled with their units. I know, I am saying this at the cost of sounding like a fanboy, but that's Noctua for you.
