Noctua NH-U12P SE2 Dual Fan Quiet CPU Cooler, Intel and AMD

- Replaces the Noctua NH-U12P SE1366 Dual Fan CPU Cooler

We don't think the boffins at our biggest-selling cooler brand Noctua went on holiday this summer. The new NH-U12P SE2 replaces the NH-U12P SE1366 and provides compatibility with both Intel and now AMD processors.

Recommended by more than 150 leading international websites and magazines, Noctua's NH-U12P series has become a benchmark in premium quality quiet cooling. The new NH-U12P SE2 comes with two NF-P12 fans for further improved performance and adds support for LGA1155/6 and LGA1366 via the latest SecuFirm2™ multi-socket mounting system. Topped off with Noctua's award-winning NT-H1 thermal compound, the NH-U12P SE2 forms a complete quality package that continues the NH-U12P series legacy of superb quiet cooling performance.

Customer Reviews

A bit too big for my motherboard.


There was a slight issue with this beast, it went over 2 of my RAM-slots. Otherwise a very good CPU cooler and silent as a ninja.

Oh yes, it's very good and very quiet BUT beware


It's bleeding enormous. It was so tall that I had to take my mobo off the sliding installation backplate and re-install it inside the (full size) case which was a bit fiddly. But I am pleased with it as it is exceptionally quiet. Just be sure it will go inside your system!!!

Superb cooler!


I spent weeks reading reviews on a variety of 1156 coolers before deciding that this was the one to get. It is a beast. I had to remove a side fan from my NZXT Lexa case to get it in. The clips on the fans were a bit fiddly but the rest of the install process was relatively easy.

I'm running both fans at 100% speed and it's still quieter than the stock fan (not surprisingly). My Core i5 750 idles at 35 degrees on cores #0 and #2 whilst #1 sits around 32 degrees and #3 is at 30 degrees. I've read some reviews which encountered the same issue. Perhaps I need to reapply the thermal grease.

Playing Crysis pushes it up to 50 degrees which is still relatively cool. I haven't tried it with max utilisation of all CPU cores yet but I expect the temps will still be good.

So overall, a very good cooler and an excellent service from Quiet PC.
