CPU coolers have come along way over the past decade when most of them were just a piece of heatsink with a noisy small fan strapped to them. Noctua is now synonymous with top tier products in this segment. Today we are looking into the single tower category of their new chromax.black treatment, alongside the D15 and the L9a/i. The NH-U12S has this new cool coating, while maintaining the proven slim-tower heatsink design and the NF-F12 PWM fan which means excellent cooling performance with superb quietness of operation and outstanding RAM, case and PCIe compatibility.
First about Noctua
Established in 2005, Noctua took international silent enthusiasts’ hearts by storm and quickly developed into one of the most acclaimed suppliers of premium quality quiet cooling products. Today, Noctua is present in more than 30 countries across the globe and working with several hundred sales partners. Chosen by noise-conscious PC users, system integrators and industry clients alike, Noctua has become synonymous with impeccable quality, excellent customer service and class-leading quiet cooling performance.
Designed in Austria, Noctua’s premium cooling components are internationally renowned for their superb quietness, exceptional performance and thoroughgoing quality. Having received more than 6000 awards and recommendations from leading hardware websites and magazines, Noctua’s fans and heatsinks are serving hundreds of thousands of satisfied customers around the globe.
Prices and Availability
Noctua charges only $10 extra for the new black treatment which is reasonable, considering that the fan is black as well.

Visual Inspection & Installation
As you would expect, the box design is different to the normal one as well to make it obvious that what you are getting is the new all black variant.
The presentation and all the information regarding specs are nicely illustrated on all of the remaining sides.
This is how you organize and present an accessory box !
You get everything you need to tackle any modern socket (besides the TR4 and LGA775).
1x NF-F12 PWM chromax.black premium fan (pre-attached to the heatsink)
1x Low-Noise Adaptor (L.N.A.)
1x NT-H1 high-grade thermal compound
1x Black SecuFirm2™ Mounting Kit
4x Black anti-vibration pads
2x Fan-clips for a second NF-F12 fan
1x Noctua Metal Case-Badge
1x Custom long Philips screwdriver
3x Booklets which cover all of the installation instructions
Underneath the accessory box, we have the NH-U12S heatsink with the NF-F12 PWM chromax.black premium fan pre-attached.
The new chromax.black coating looks absolutely stunning !
Overall the NH-U12S measures 158mm in height, 125mm in width and 71mm in depth with a weight of 755g (including the fan).
It has 50 aluminium fins which are held together by five 6 mm thick all-copper heatpipes. The all-copper nickel plated base is the only part of this cooler which is not painted black.
The fan when installed will sit flush with the heatpipes. Also Noctua gives you the option to cover the top of the heatsink with a plastic adapter via the NA-HC1 series.
The NF-F12 PWM chromax.black fan is rated up to 1500 RPM, 93.4 m³/h max airflow while not passing 22,4 dB(A) of noise. It is guaranteed to last over 150,000 hours of operation thanks to its premium SSO bearings, which translates to over 17 years. Suffice to say that the fan will outlast many builds and upgrades.
You will need to select the appropiate parts depending on your platform (socket). We have an i7 from the Sandy Bridge-E generation, thus socket 2011. Here things are really easy. First step is to mount the 4 double sided screws.
Step 2 requires these brackets to face upwards. Also in this step you need to choose how the heatsink will face – either parallel with the ram (like in our case) or perpendicular (facing upwards towards the top of the case).
Tighten down the brackets via these 4 thumbscrews which constitutes step 3.
Next, apply the thermal paste. A slighter bigger blob of paste is required here when compared to the smaller CPU sockets.
Place the heatsink without the fan and then secure it via the 2 big spring loaded screws on each side.
In the last step re-attach the fan(s) and plug the 4 pin PWM port in the header on the motherboard. Male sure you check the clearance around the socket area. As you can see, this G.Skill Trident X DDR3 kit is pretty tall but on this ASUS GENE X79 motherboard, the Noctua NH-U12S has zero issues in any direction. Also, if you have RAM kits that have a standard height heatsink (under 40 mm tall) the fan will clear them as well.
- Let’s spice things up by using a 130W stock TDP Intel Sandy Bridge-E CPU the 3820 on the X79 platform
- The CPU will be tested at stock values and then overclocked to 4.5 GHz (36×125) at 1.380v
- As the main torture test, we will employ the AIDA64 and then some 3D benchmarks as well
- Room temperature is set at ~ 18°C
- For the noise testing, we used our Pyle PSPL01 placed 30 cm away from the setup – all other fans will be off and the fans of the GPU(s) will be off and/or set at minimum
- Thermal paste used – Noctua NH-H1
- We will compare the results to other CPU air coolers
- All fans will be left on the auto % rpm curve to simulate real life usage patterns
- Any results over 90° C in any condition are considered a fail

Testing, Results & Analysis
Let’s start in order of CPU load difficulty. First up is the Cinebench R15 test. On the left is the CPU in stock form while on the right we have the results for the overclocked scenario.
Then Cinebench R20 is a more modern up to date multi core benchmark suite. So naturally we will see a bigger load and thus a larger temperature figure that R15.
In AIDA64 we isolated the stress test just for the CPU and thus we should get the highest stress scenario for the CPU. Mind you the R20 proves to be almost as demanding as the stress test so the numbers are very close.
The easiest test today is a 10 minute session in Metro 2033 which only makes the CPU use bearly 25% of it’s total computing power thus here the results will be very good across the board.
Now let’s inspect the noise levels. Noctua and BeQuiet! are the best in class regarding noise output so naturally they will dominate here as well.
The main conclusion to acknowledge is the fact that the Noctua NH-U12S chromax.black performs excellent even when we take a 130W stock TDP CPU and overclock it, and still manages to keep it cool. All of this while never disturbing your eardrums. The only thing with it is that it has close competition in performance numbers and in price with the Dark Rock Slim from BeQuiet!. Also if you take into account that the Cooler Master 212 is the standard in single tower CPU coolers from a best buy perspective (which also can be had with RGB), the NH-U12S even in black, will put buyers in a slight thinking mode if they will go for it. Don’t get me wrong, the Noctua is worth the price alone just from the noise, cooling performance and overbuilt quality trio point of view.
The Noctua NH-U12S chromax.black will outlast many builds given its insane build quality and craftsmanship. With 6 years warranty, amazing cooling and noise output ratio, very easy installation process, zero interference even with two fans attached, it’s very hard not to recommend this CPU cooler as one of the best single tower heatsinks out there. The new all black coating carries a $10 premium over the standard U12S but it’s definitely worth it for those who want to color coordinate their builds as well. It has a lot of competition from other brands but if you are looking for the best overall when money is no object, then this is it !
+ Industry leading built quality
+ Zero interference even with two fans
