Overclockers Online has posted a new review on the Noctua NH-U12P

All things considered, Noctua's NH-U12P performed admirably well. The cooler's design and build quality are excellent. In terms of compatibility issues, there were none - the cooler has ample clearance from memory and other components. Also, it can be rotated and thus can be installed in two different orientations. The only clearance issue that might arise is due to its height as it may interfere with some cramped cases. Installation was very easy except for the fact that it requires motherboard removal. Performance is top notch and it is easy on the ears thanks to the quiet NF-P12.
