Noctua NH-L12 Low Profile High Performance CPU Cooler, Intel LGA2011,1150,1151,1155,1156,1366,775 + FM1,AM3+/AM3/2+/2

Noctua NH-L12 CPU Cooler
Noctua NH-L12 CPU Cooler
Product Overview
The NH-L12 is a low-profile quiet cooler designed for use in small form factor cases and HTPC environments. With its flexible NF-F12 (120mm) / NF-B9 (92mm) dual PWM fan setup, the NH-L12 can be configured either for full performance in dual fan mode or extra-low profile (66mm) with the top fan removed. Bundled with the award-winning NT-H1 thermal compound and Noctua's SecuFirm2 multi-socket mounting system, the NH-L12 packs everything a premium quality quiet cooler needs into a highly compact package.

120/92mm dual fan design
Thanks to its exquisite dual fan setup consisting of Noctuas highly optimised NF-F12 (120mm) and NF-B9 (92mm) premium fans, the NH-L12 pushes the bar in terms of low-profile quiet cooling performance.

Extra-low profile in 92mm single-fan mode
The NH-L12 can be used with the NF-B9 92mm fan only in order to reduce the overall height to 66mm. This way, the cooler is suitable for many typical ATX or Mini-ITX enclosures and ideal for whisper-quiet HTPC systems.

PWM support and Low-Noise Adaptors
The NH-L12s NF-F12 and NF-B9 fans support PWM for convenient automatic speed control. In addition, the maximum fan speed can be reduced to 1200/1300rpm using the supplied Low-Noise Adaptors for even quieter operation.

SecuFirm2 mounting system
Noctuas enthusiast grade SecuFirm2 multi-socket mounting provides broad socket compatibility (LGA 2011, LGA1366, LGA1156, LGA1155, LGA1151, LGA1150, LGA775, AM2, AM2+, AM3, AM3+, FM1) and meets the highest demands in safety, performance and ease-of-use.

Mini-ITX mounting without backplate
Some Intel based Mini-ITX mainboards dont allow for the installation of backplates. The NH-L12 thus comes with an extra set of Intel mounting bolts which make it possible to install the cooler without using the SecuFirm2 backplate.

NT-H1 thermal compound
Noctua's much-acclaimed NT-H1 is a well proven pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and outstanding reliability.

Rated 3.5 out of 5 by 4 reviewers.
Rated 1 out of 5 by Not fot Silverstone SST-FTZ01B I purchased this for ITX gaming system, so it would be fair do not to accept the same results for a bigger case. In the Silverstone FTZ01 it does not work very well, idle temp 46c with the low 92mm fan fitted, and case fan above, the 25mm noctua fan does not fit into the case, the mainboard i'm using is asus impact vii with 4770k cpu, the cooler does fit the board. Also noted when the Noctua 92mm fan is fitted only and the system is cold, cpu fan errors are reported by the mainboard. 21 June 2015
Rated 5 out of 5 by Great low profile quiet fan for 2011 V3 socket I bought this fan for its low profile as previously i had bought huge great towering monsters and was pleasantly surprised by this. It was low profile compared to other offerings, 2 decent size fan and heat sinks, full PWM control so quite as a mouse when needed. Fully recommend this fan for anyone building an X99 set up. 06 March 2015
Rated 5 out of 5 by Quiet and cool I recently built a new i74930K workstation and put an NH-L12 in. Really quiet and short enough to fit my 19" rack case. The new PC was so quiet I retro fitted another NH-L12 in my older workstation and used the included voltage adaptor cables to run the chassis fans. Now that PC is extremely quiet too. No more constant white noise in the studio! The noisiest thing is the room now is the fridge. On my Asus P9X79 Deluxe motherboard the NH-L12 prevents ram modules taller than 43mm being fitted in the slots nearest the CPU. Not a problem if you're using four modules but worth thinking about if you want to populate all eight slots. CPU idles at 42C, hits 70C under load with all 12 cores topping out. Now, if only Noctua made fridges . . . 19 February 2014
Rated 3 out of 5 by Couldn't use it with tall memory I bought this to go on an ITX system (Gigabyte A85) which needs to use fast ram, so i bought this to keep the APU at decent temps, unfortunately the upper heatsink is too wide for my tall RAM, so it's not being used. I could have done some DIY and shaved the size down, but at the price I paid I couldn't! It will get used for a future HTPC build (hopefully). It should be OK for a typical HTPC build with low profile RAM. 07 November 2013
