Continuing the legacy of Noctua’s classic NH-U-series, which has received more than 500 awards and recommendations from international hardware websites and magazines, the NH-U12S has become a benchmark for slim, highly compatible 120mm single tower coolers. The SE-AM4 version is a dedicated special edition for AMD’s AM4 (Ryzen) platform, featuring the latest SecuFirm2™ mounting system for AM4. Topped off with the renowned quiet NF-F12 PWM 120mm fan, Noctua’s proven NT-H1 thermal compound and a full 6-year manufacturer’s warranty, the NH-U12S SE-AM4 forms a complete premium-quality solution that combines outstanding performance, superb acoustics and excellent compatibility for AM4 systems.
Please note that as a dedicated special edition for AM4, the NH-U12S SE-AM4 comes with AM4 mounting hardware only, and that for this cooler, Noctua cannot provide free mounting kits for other current sockets such as LGA115x or LGA2011-x. For the NH-U12S SE-AM4, these mounting kits can only be purchased in retail or online shops (NM-i115x for LGA115x and NM-I2011 for LGA2011-x). Future mounting upgrades will be provided free of charge as usual if technically possible.

NH-U12S SE-AM4 Review

Noctua NH-U12S SE-AM4 is well designed, high quality cooler which is one of the most interesting options for AMD Ryzen processors. It can handle 8 core processors without issues and at the same time keeps PC quiet. Users can’t ask much more from a CPU cooler.
Test verdict: "Noctua NH-U12S SE-AM4 is one of the best cooling solutions for AMD Ryzen processors and is clearly recommended by Funky Kit’s redaction!" (Bartosz Waluk, FunkyKit.com)

NH-U12S SE-AM4 Review

Looking at the load results, the Noctua NH-U12S SE-AM4 does an excellent job of shedding the thermal load generated by the processor. Unsurprisingly, the NH-U12S SE-AM4 offers excellent acoustic performance.
Test verdict: "When it comes down to it, the NH-U12S SE-AM4 proved to be a very powerful tower cooler while managing to fit all of its performance in a smaller, lighter package than most of its competitors." (Ambrosidou Nat, XtremeSystems.org)

How big is the NH-U12S and how much clearance does it provide for RAM and chipset coolers?

Please refer to the following drawing for the exact measurements and clearance for RAM and chipset coolers:

U12S

Should I take the cooler off before transporting my system?

As it is not possible to reliably calculate or control the forces that act upon a system during transport (e.g. in shipping), we generally recommend, for safety reasons, taking the fan off the heatsink in order to reduce the weight below 700g. Noctua cannot be held responsible for any damage that may arise due to excessive stress during transport if you keep the fan installed.

Which Noctua CPU coolers are compatible with AMD AM4 (Ryzen)?

The following models include a mounting-kit for socket AM4 and are thus compatible out of the box:

NH-D15 SE-AM4
NH-U12S SE-AM4
NH-L9x65 SE-AM4

The following models can be made compatible with the AM4 socket free of charge using the NM-AM4 upgrade-kit:

NH-C12P
NH-C12P SE14
NH-C14
NH-C14S
NH-D14
NH-D14 SE2011
NH-D15
NH-D15S
NH-D9L
NH-L12
NH-L9x65
NH-U12
NH-U12F
NH-U12P
NH-U12P SE1366
NH-U12P SE2
NH-U9
NH-U9B
NH-U9B SE2
NH-U9F

The following models can be made compatible with the AM4 socket free of charge using the NM-AM4-UxS upgrade-kit:

NH-U14S
NH-U12S
NH-U9S

The following models can be made compatible with the AM4 socket using the NM-AM4 upgrade-kit but are not eligible for Noctua‘s free mounting offer, so users have to purchase the kit at local resellers:

NH-U12DO (Note that the A3 version is not compatible!)
NH-U12DX
NH-U12DX 1366
NH-U12DX i4
NH-U9DX i4
NH-U9DX 1366
NH-U9DO (Note that the A3 version is not compatible!)

The following models are not compatible with the AM4 socket and can not be upgraded:

NH-L9i
NH-U12DO A3
NH-U9 DO A3

We also aim to provide an upgrade-kit for NH-L9a, but due to some late changes to the AM4 platform, it is not yet clear whether installation will be possible. We are currently exploring the available options and will provide more information at a later date.

How can I determine if the motherboard’s UEFI BIOS is overclocking my processor by default and deactivate this automatic overclocking?

Most motherboard vendors allow their overclocking-enabled products (e.g. those with Intels X- or Z-series chipsets) to run the processor at increased clock speeds by default, without requiring any user action at all. Since TDP (Thermal Design Power) limits are usually also disabled by default, this leads to the CPU exceeding the rated TDP to a varying degree, depending on the used applications and their workloads. Due to the increased heat output of the CPU, you may see higher CPU temperatures than expected.

In order to find out if your motherboard is overclocking your processor by default, please enter the UEFI BIOS and select the “advanced” or “overclocking” menu. There you should be able to find options such as “MultiCore Enhancement” (options: enabled/disabled), “CPU Ratio Apply Mode” (options: all/per core) or similar. To disable the automatic overclocking, adjust the settings either to “disabled” or “per core” and make sure that the individual multipliers match the original specifications.

In doubt, please contact your motherboard vendor for detailed instructions on how to disable this feature.
