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. Features
• Low profile cooler, ideal for media PCs • Excellent performance for its class • Dual fan mode • Supplied with NF-F12 and NF-B9 PWM fans • Compatible with Intel LGA2011/1150/1151/1155/1156/1366/775 and AMD FM1/AM3+/AM3/AM2+/AM2

Intel Core 2 Duo (Conroe)
Date Issued: 20th Oct 2008
The purpose of this TekSpek is to delineate the publicly known features of Intel’s next generation desktop microarchitecture. Codenamed Conroe and officially titled Intel Core 2 Duo, it’s loosely based on the current mobile Yonah (Core Duo) underpinnings.
This TekSpek explains what AMD’s AMD64 CPU instruction set architecture (ISA) is, shows what CPUs implement it from both AMD and Intel, and explains what software is available to run on those 64-bit consumer processors.
The modern PC is potentially a mass of heat output and heat production hot spots. With CPUs rated at more than 100W of heat output, single graphics boards carrying similar ratings (and people want to run two!), multiple hard drives the norm, lots of memory and mainboards covered in heatpipes to combat toasty core logic and PWM circuits, a PC appreciably warming up a room when it’s working hard is no joke.
There’s been a lot of hype about Intel’s Core 2 recently, even since they launched Core in fact. Words like Conroe, Badaxe and Allendale have been flying around. The bottom line is that Core 2 is the name of Intel’s latest line of CPUs, based on a new micro-architecture, designed for speed and efficiency.
Anybody who has been near their share of computer systems will appreciate that not all systems make the same amount of noise. There are a number of reasons for why this is so. Firstly, a computer makes noise for different reasons. Generally, anything mechanical is going to make noise.
Noctua NH-L12 Low Profile High Performance CPU Cooler, Intel LGA2011,1150,1151,1155,1156,1366,775 + FM1,AM3+/AM3/2+/2 is rated

Excellent performance and value for small buildsI have one of these sitting in a small gaming build, and it performs flawlessly on an i5 6600k and is remarkably silent. It has the right design shape to slot over micro-ATX motherboard heatsinks and RAM (unless you get the extended heatsink ones which will be incompatible but could potentially be a problem depending on the motherboard you use).
As usual, it comes with quite a few accessories, brackets for AMD and Intel CPUS, fan speed reducer cables, some Noctua TIM with enough for a few extra applications and their extra-long warranty. And best of all? The Noctua Phillips head screwdriver. Noctua will also send you new brackets if a newer socket comes out which is incompatible with it.
I reiterate that you have to be cautious with RAM slot compatibility as some protruding heat pipes can block a DIMM slot depending on the motherbaord and build. See the picture of my build for example. I used a tiny case, and the only way of installing it was to block a DIMM slot. So it which isn't a problem for me.
Otherwise, it is perfect for silent builds and maintains very low temperatures.
In case you are wondering what my build is:
Asus Z170-M Plus Mobo
2x8GB Corsair Veng LPX DDR4-3200 RAM
Corsair CS650M PSU
XFX RX480 8GB GPU

Not fot Silverstone SST-FTZ01BI 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.

Great low profile quiet fan for 2011 V3 socketI 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.

Quiet and coolI 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 . . .

Couldn't use it with tall memoryI 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.
