Reviews

“It is amazing to see this cooler pulling out the same results passively cooled as the Cooler Master’s fan cooled unit (Hyper 48). When we install the 120 mm fan, the heatsink truly blows away the competition. Editor’s Choice Award. ”- Metku.net

“Noctua contacted us with a bold boast about their product, and proved their initial comments were not boasts, but were a description.” - PC Apex

“...a great example of a heatsink that can be used for either efficiency or quiet computing. We would recommend the Noctua over Zalman’s [FS-C77] though: it’s more efficient in the same price range and has the option of running passively, if your processor has a low enough TDP.” - PC Plus Magazine

“The Noctua cooler dethroned the Scythe Infinity as the Pure Air Champ and came up just one degree short of the Amanda, which will use more power and is a lot noisier due to its dual 90mm fans. The NH-U12F is one great cooler. The performance levels which it demonstrated here today are truly awesome.” - Pro-Clockers.com

“Testing the NH-U12F with the different fans we received from Noctua was more pleasurable than any other heatsink and fan combo I’ve tested, purely because it was simple to install both onto the motherboard and the fan was easy to mount and it was extremely quiet in operation.” - CPU3D

“The Noctua NH-U12F has one of the best machined contact areas that I have ever seen on a non hand lapped cooler. Can I recommend this product? The answer is quite simple and only two words long: HELL YES!” - Bjorn3D.com
