Processor fan for Intel socket and AMD

Overview

Top-of-the-range Ventirad based on the famous NH-L12


A worthy successor to the famous NH-L12, the NH-L12S is a top-flow fan for ultra-powerful CPUs, offering great compatibility and modularity. Thanks to its deeper fin stack and the integration of the famous NF-A12x15PWM fan , the NH-L12S single fan model provides a level of cooling that lives up to Noctua's reputation.

The installation of the fan at the top of the heatsink ensures compatibility with RAM modules up to 48mm high, while the installation of the fan under the heatsink ensures perfect compatibility with many HTPC cases thanks to the total height of the ventirad not exceeding 70mm. In addition, the remote design frees up the last PCIe slot on most μATX and ATX motherboards. Complete with the high-end SecuFirm2 multi-socket mounting system,Noctua's renowned NT-H1 thermal paste and backed by a full 6-year full manufacturer's warranty, the NH-L12S is a high-performance, high-quality top-flow solution for the most demanding users.


C-design for optimum flow

The optimised C-shaped design of the NH-L12S ensures optimum quiet cooling while minimising the overall height compared to traditional 140mm tower fans. This design also ensures excellent ventilation of memory modules and components adjacent to the socket on the motherboard.

A remote design


Compared to the design of the original NH-L12, the design of the new NH-L12S offers a double axial offset.On most μATX and ATX motherboards, this design frees up space in the last PCIe slot (the heatpipes' curves face the PCIe ports or the rear connector panel).

Low profile" installation

The installation of a single NF-A12x15 PWM fan fixed under the stack of fins gives the NH-L12S an overall height of just 70mm, much less than traditional tower fans with 120 or 140mm fans, making this type of mounting perfectly suited to many desktop / HTPC cases.

Large space" mounting

Installinga single NF-A12x15 PWM fan at the top of the heatsink leaves more air space under the stack of fins. This type of assembly offers perfect compatibility with RAM modules equipped with 45mm high heatsinks, as well as with socket heatsinks.

SecuFirm2 fastening system


Noctua SecuFirm2 mounting systems have come to epitomise quality, safety and ease of installation. The SecuFirm2 system supplied with the NH-L12S guarantees perfect contact pressure and ease of installation on all current sockets.

6-year manufacturer's warranty


Noctua products have earned a solid reputation for exceptional quality and longevity. Like all Noctua fans, the NF-A12x15 PWM has an MTBF of over 150,000 test hours and the NH-L12S package comes with a 6-year manufacturer's warranty.

    The sound of the wind blowing through the branches

    It's amazing what Noctua can do with their fans. From the quality of the packaging to the components themselves and a wide variety of connectivity options, you can feel that Noctua is putting in a lot of effort. On the loss side: 20db for a 75mm is very good. All the assemblies are supplied and compatibility with motherboards can be checked on their site... in a word: perfect! Compatible with ASUS PRO H610M-C D4-CSM but not in low-profile assembly because of the close proximity of the Ram strips.

    Ideal for small housings

    Depending on the type of motherboard and the arrangement of the components, such as RAM and graphics card, this fan offers two mounting positions and two heights for the fan, making it the ideal companion for small cases. (example ASUS GL10DK).
    It allows a reasonable overclocking of your Ryzen while remaining silent.
    Be careful about the height of the RAM bars if you want to use all 4 slots.

    Difficult to install

    The cooling unit seems to be as quiet as promised. However, it is extremely difficult to install (on an AMD, in this case). It's a real pain to line up the screws, to screw it in without damaging the fan blades. A real pain.

    Top and quiet!

    Excellent ventirad! cools the processor well especially in games that are quite greedy and in a climate of high heat in summer like in New Caledonia. Nothing to say, it's great.

    Correct

    Don't run on a msi b450 mortar titanium motherboard in low position!
    For the rest nothing to say.
