Description

Noctua's premium cooling components are internationally renowned for their superb quietness, exceptional performance and quality. True to the spirit of Noctua’s redux line, the NH-U12S redux is a streamlined, accessibly priced version of the iconic NH-U12S that has established itself as a benchmark for slim, highly compatible 120mm CPU coolers. The redux version uses the same proven heatsink layout that ensures 100% compatibility with tall RAM modules as well as excellent case and PCIe compatibility. Thanks to the popular NF-P12 redux-1700 PWM fan with automatic speed control, it provides high performance under load and runs whisper-quiet at idle. At the same time, Noctua’s renowned, professional SecuFirm2 mounting system and the pre-applied NT-H1 thermal compound make installation child’s play. Backed up with Noctua’s trusted quality, the NH-U12S redux is a smart, affordable choice for a quiet, high-quality 120mm cooler. Standing 158mm tall, the NH-U12S redux is short enough to fit most modern mid- or high-end tower cases. Measuring 125mm wide (including fan and fan clips), the cooler stays clear of the top PCIe slot on most standard ATX or Micro-ATX motherboards, ensuring optimum compatibility with multi-GPU setups. Thanks to its slim design with only 45mm fin depth, the NH-U12S redux will not overhang the RAM slots on any current platform. This gives the user full access to the memory modules and ensures 100% compatibility with modules that feature tall heat-spreaders or RGB lighting. Specifically designed for pressure-demanding applications such as on heatsinks, the classic NF-P12 is a long-standing favourite among quiet cooling enthusiasts. The higher-speed 1700rpm redux line version supports PWM for automatic speed control, which allows it to run near silent most of the time and provide massive performance when necessary. The optional NA-FK1 fan kit makes it possible to upgrade the NH-U12S redux with a second fan in order to achieve even better performance. Containing a second NF-P12 redux-1700 PWM fan, fan clips, anti-vibration pads, a y-cable and Low-Noise Adaptors, it gives plenty of options to fine-tune the cooler for further improved efficiency or quietness of operation. Nickel plated Copper (base and heat-pipes), aluminium (cooling fins) 120x120x25 Following the idea of Noctua’s redux line, the NH-U12S redux takes the proven concept of the original NH-U12S and reduces it to its essential core: a quiet, quality-made 120mm cooler with streamlined accessories that is highly compatible and easy to install.

    • Excellent cooler for efficiency and budget
I purchased this along with its second fan kit. Mounted on a ryzen 7 5700G which I then overclocked to 4.5Ghz all core stable at 1.35V. When running heavy benchmark loads, burnin tests, and intense workload programs the max temp was 40°C. Fan noise is negligible at best and the pwm keeps them in a good zone without needing the power limiter. I used to build systems professionally at work and have used most high end components available so I get to test a lot of configurations. Normally my preferred air cooler is the be quiet dark rock pro 4, but this little beast has honestly stolen my affections. In most workloads the performance is near identical to coolers twice its cost so it really is a good value. Downside, its not the nicest looking cooler. It has a decent style with the grey and silver so you can pull of some nice looking builds, but its no head turner and honestly is best for systems that arent showcases. Bottom line, an exceptional cooler for a very reasonable price. I first tested this on intel 12th gen and they did great with non k sku models and a single fan. If you are doing a 12700k, 12600k, or their new 13th gen versions then this guy is a great buy. If, however, you want to oc the intels, then you may want to look into 240mm aio or bigger fan solutions. If you are looking to build a good performance amd 5000 series based system, look no further. The great efficiency of the amd 5000 means this cooler does extremely well with these cpus. I selected the 5700g for both budget and my needs which arent crazy. Im not really into buying the end all be all and tend to lean more into efficiency and capability. This cooler keeps my system stable and running exceptionally well and I still have headroom to work with. No question, while there are cheaper units and some better performing units none have both as well as this. This is the best budget cooler available today. ... show more

    • Lives up to the Noctua name for half the price
Purchased this with the optional second fan as an upgrade from the stock cooler that comes with my 5600. I had been looking at purchasing a Noctua cooler, specifically the NH-U12A or the NH-U12S but could not justify pulling the trigger on a $100+ cooler when the stock cooler was doing a good enough job. But then I found this cooler with basically the same performance for half the price, and I knew I had to get it. PROS: -AMAZING cooling! With the stock cooler, my CPU would get to 90+ degrees while performing a 10 minute Cinebench. With this cooler, it barely gets above 60 degrees while performing a 30 minute Cinebench test. While gaming, even under the most CPU stressing game I have (Dead Space Remake) it stays under 65 degrees with PBO enabled. -This thing is QUIET! Like I said, I had purchased the secondary fan for a push/pull configuration on my cooler and even with the second fan, this thing is silent. Really the only noise coming from my PC is from the GPU fans spinning up. Before, my PC was noisy with the stock cooler, but I didn't realize HOW noisy it was until I put this one in. -You cannot overtighten this cooler because of the spring loaded screws on the cooler -Comes with Noctua thermal paste pre applied, so you do not have to worry about paste, but get some just in case. Arctic mx-4 is $5 extra CONS: -It is tough to get the mounting hardware on without help. I managed to do it but it would be 100x easier with someone helping, or by removing the MOBO from the case. But I was lazy and didn't want to deal with that. Plus, some of the standoffs for my board are under where the fans end up sitting, so I still would have had issues with it. -Some people have had issues with motherboard compatibility, but this could be user error. I use a Gigabyte B550M DS3H and had no issues. This cooler uses the backplate that came with the board for AM4. Intel uses the included backplate. -The threads for the screws are on the mounting hardware, and when you loosen the screws on the cooler, they are not free of the screws on the mounting hardware, keeping you from turning the cooler to break the seal from the thermal paste. Since this comes with Noctua paste pre applied, good luck getting this off without a fight. -Attaching the fans is hard as hell, especially if you do it in your case. I found that doing the secondary fan (if you buy one) first, then the front fan is WAY easier than doing it the other way. And the fans might block standoff screws if you put them on outside of the case. I highly recommend this cooler, and its good to see that the Noctua name holds up even on a more budget option. ... show more

Let me begin with some clarification. I have not yet used my pc with this cooler in practical applications yet. However, I have ran the Heaven benchmark and Cinebench R23 with this cooler installed. I’m running a Ryzen 7 5000 series and there is about a 25 degree difference in running those two benchmarks between the Noctua cooler and the AMD Waith stock cooler. The Noctua cooler definitely comes out ahead, which I knew it would, by a 25 degree difference. The idle temp is about 5 degrees cooler. I’d love to say the fan is quieter, but I don’t know. The fan on the Noctua cooler hasn’t had to ramp up like the AMD Wraith cooler fan had to. For the temps I was at, 53 degrees under load, I couldn’t hear the fan. While this Noctua cooler is a “budget” cooler, it has performed wonderfully thus far. Installation is very straight forward, with clear instructions for the inexperienced. Noctua makes great products and is well established in the PC cooling business. ... show more

    • Versatile, and fairly straightforward to install. Good performance
I installed this heatsink on an LGA 1700 motherboard and encountered no problems with it. The instructions offered clear graphics on how to mount and construct the heatsink for the relevant chipset I was using. Temperature monitoring shows that CPU maintains an average temperature of around 25-30C when not under load, and rarely goes too far above 40C when it is under load. This is a stark improvement over my previous computer with its stock cooler that would idle around 40C and go up to 60C when under load. The item did arrive with some minor cosmetic damage, as the mounting brackets of the fan bent some of the aluminum fins of the heat sink slightly. While this doesn't bother me and isn't noticeable inside the case, nor did it affect the ability of the fan to be secured on that side, it may be of concern to others and due to the way this item is packaged and transported it could be hard to completely avoid cosmetic damage of any kind. Finally, I recommend everyone double and triple check that this item can fit in their case and on their motherboard. While its orientation and fan placement are both flexible, the width and height of it is definitely much larger than your typical stock cooler and you may need to compromise on a placement that can reach your motherboard's fan ports or even fit on your motherboard in the first place, to say nothing of making sure your case is wide enough to close the side panel. ... show more

Works great and is quiet enough for the cooling power. It’s decently tall but it performs well for the price.

    • Great cooling fan for processors not known to be really hot.
Great fan for midrange and budget processors. Doesn't have enough cooling power behind it for high performance processors with lots of heat such as my Ryzen 7 5800x; as a result, you will loose top boost clocks prob by 0.2-0.4 GHz. Noise level is some what noticable and high pitched if you are performing heavy CPU tasks, but shouldn't be a problem most of the time especially with headphones. It's a little large for what you would expect as a single fan heatsink, but not overtly so. Mounting was pretty easy. If you need a cooler for a non top-line, high heat processor I highly recommend. High quality for a great price. ... show more

    • Impressive cooling capabilities
just upgraded my system from a 7700k to a 12700k and was worried about what cooler I should get, as I’ve heard the 12th gen processors can run pretty hot. After some researching, i knew I didn’t want to run an AIO (I’m pretty novice at PC building and leak horror stories have kept me away) and wanted to stick with a traditional heat sink and fan cooler. I ended up choosing this one and so far, I’m pretty impressed. It was fairly easy to install, and comes with instructions and all the hardware you will need to mount it to a LGA1700 board. After starting my system up, the temps stay around 38c to 45c at “idle” and under load, they hover around 56c to 65c. Haven’t seen it go over 65c. The only games I’ve tried so far are cyberpunk, days gone and ready or not for reference, as I’m not sure what games will have what impact on this fan processor combo. Overall, i pretty happy with this cooler so far. It’s kept my temps low and looks nice with my PC. I think i might even order the extra fan kit, to further cool it down, even though as it stands, I don’t think it’s necessary. For anyone wondering if this is a good choice for the 12700k, I’d say its a pretty safe bet, but your mileage may vary. ... show more
