Noctua NH-U12P CPU Cooler: Noctua Strikes Again

June 26, 2008 by Lawrence Lee

Noctua NH-U12P
LGA775 & K8 CPU Cooler
Street Price
~$60 USD

The recently reviewed Noctua NH-C12P turned out to be the best top-down blowing CPU cooler we've seen to date. The NH-U12P is an update of the widely-acclaimed NH-U12, a formidable performer in its day. Some small changes have been made to the design, but the most visible difference is the inclusion of their NF-P12 fan.

The box. Noctua has an affinity for all things brown.

Few manufacturers give fan selection much serious thought. Noctua designed the NF-P12 fan especially for use in high-impedance applications, such as heatsinks. The "P" in the model name stands for "pressure." Not only is it supposed to have unique properties, it is also extravagantly priced. The NF-P12 retails for about US$20 on its own. When we tested the NH-C12P however, we found that the NF-P12 did no better than two other well-known fans, the Nexus Real Silent case fan, and Scythe Slip Stream L. The NH-U12P has similar fin thickness and spacing, so so we expect it to perform similarly.

The provided mounting hardware is neatly separated. A screwdriver is provided just in case.

Noctua NH-U12P: Key Features
(from the product web page)
Feature & Brief
Our Comment
4 dual heat pipes
4 dual heat pipes, soldered joints and widely-spaced aluminium cooling fins guarantee optimal heat dissipation even at low fan speeds.
While most premium heatsinks now come with six heatpipes, Noctua bucks the trend here with only four.
NT-H1 Award winning NH-U design
Noctua's NH-U coolers allow for perfect airflow direction and have received more than 150 awards and recommendations from leading international websites and magazines.
The U-shaped heatpipe is now common-place.
NT-H1 NF-P12 premium fan
The NF-P12 has been specifically developed for applications like CPU cooling and brings the performance of the NH-U12 to a whole new level. Thanks to psycho-acoustic optimizations and Noctua's premium-grade SSO-bearing, the NF-P12 achieves exceptional quietness and long-term stability.
The NF-P12 is designed with high static pressure in mind.
NT-H1 Improved compatibility
Thanks to its raised fin-stack, the NH-U12P offers improved compatibility with main boards featuring very high chipset coolers.
The NH-U12P's fin stack is higher than its predecessor, creating more clearance for northbridge and VRM heatsinks.
NT-H1 SecuFirm™ multi-socket mounting system
Noctua's professional SecuFirm™ mounting system for LGA 775, AM2 and AM2+ provides superior reliability and contact pressure.
A secure mounting system is essential for any heatsink.
NT-H1 Incl. Noctua NT-H1 high-end thermal compound
Noctua's NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and long-term stability.
For continuity, we won't be using their thermal compound. We'll take their word for it.
