Product Description

NH-D12L Header

The NH-D12L is a low-height 120mm class CPU cooler that has been conceived to combine outstanding quiet cooling performance with superior case compatibility. At a height of only 145mm (13mm lower than Noctua’s regular 120mm models), it fits many 4U enclosures as well as narrower tower cases that have been previously limited to solutions with 92mm fans. At the same time, its five heatpipe dual-tower design and state-of-the-art NF-A12x25r 120mm fan allow it to achieve a level of efficiency that surpasses many full-height 120mm models. Thanks to its single fan configuration and asymmetrical fin stacks, the NH-D12L provides 100% RAM compatibility on AMD AM4/AM5 and LGA1700/1200 by staying clear of the memory slots. Topped off with the renowned SecuFirm2 mounting system and Noctua’s award-winning NT-H1 thermal compound, the NH-D12L is the perfect choice for applications that require serious cooling performance but cannot fit the larger NH-U12A.

NH-D12L

145mm height for broader case compatibility

While Noctua’s regular 120mm CPU coolers stand 158mm tall, the NH-D12L measures only 145mm. This allows it to fit not only a wide range of 4U rackmount server cases and many tower-style enclosures that are not wide enough for 158mm units, but also some larger Small Form Factor (SFF) and Mini-ITX chassis.

NH-D12L RAM

100% RAM compatibility on LGA1851/LGA1700 and AM4/AM5

Due to its asymmetric design, the NH-D12L does not overhang the RAM slots on Intel LGA1851/LGA1700/LGA1200 /LGA115x and AMD AM4/AM5 based motherboards, which ensures easy access to the modules and 100% compatibility with DIMMs that feature tall heat-spreaders or RGB lighting.

NH-U12A NF-A12x25 fan

Round-frame NF-A12x25r PWM fan

Introduced in 2018, Noctua’s NF-A12x25 is widely considered to be the best 120mm fan on the market. The round-frame variant used on the NH-D12L provides the same renowned quiet cooling performance yet makes it possible to reduce overall cooler height without risking compatibility issues with tall motherboard heatsinks or shrouds.

NH-D12L

Dual-fan options

The NH-D12L ships with a second pair of fan clips that can be used to install a second NF-A12x25r PWM fan either on the front or on the rear fin stack. However, it must be noted that the second fan will usually sit on top of either the RAM or I/O panel and thereby increase the total height beyond 145mm.

More performance at lower height

Despite its reduced height, the NH-D12L easily outperforms 92mm coolers. It can even surpass renowned 120mm units such as the NH-U12S and often comes close to Noctua’s award-winning 120mm flagship model NH-U12A.

Ive used these things for a while now. I have them in 2 hyper-v servers (one intel and one AMD) and my latest dev box with a 14th gen intel chip in it. They come with a massive radiator and can be installed blowing front to back or from bottom to top. They have a super quiet fan in them that just nestles in between the radiators and there is an option to have another fan as well if you get paranoid about heat. As far as cooling goes, these quiet fans keep my processors cool. I found liquid cooling to be overly complicated and very invasive to the computer case, plus it seemed to be very picky about where certain things had to go. With this fan unit, you just use the adapters (the instructions seem intimidating but are fairly straight forward) and the fan is pretty forgiving. I will continue to use these fans. Plus, it looks neat with all the LED lighting already in your case

J'ai monté ce Ventirad sur une carte mère MSI B550 Gaming Plus équipée d'un processeur AMD Ryzen 7 5800XT. Produit de très bon qualité, facile à installer en dépit de la taille de la bête et offrant un excellent refroidissement tout en restant silencieux (sur des jeux ou des applications de rendus 3D notamment).Ce ventirad offre l'avantage d'être compact donc compatible avec la plupart des boitiers.Livraison impeccable.

I built my new PC in January 2024 with an AMD Ryzen 7700 CPU. I'm not a big gamer but do plan to get Microsoft Flight Simulator 2024 when it comes out this year. Based on my research, this CPU will work fine for me. I like that it runs at 65W rather than higher watts that might require liquid cooling. I did my usual tons of research on deciding which cooling fan to buy. Noctua is always listed as one of the best and quietest fans. Noctua has a great website where they tell you which of their fans to buy based on your CPU and PC case. The Noctua NH-D12L fan was my only choice to use with my CPU and my Corsair Crystal 280X case. This fan fits my case and cools my CPU perfectly. It is super quiet. The cooler fan that came with my AMD Ryzen 7700 looked nice and had RGB. But reviewers didn't consider it very quiet and my own testing of it corroborated the point. This Noctua fan only comes with their brown fan. Considering that it's sandwiched between cooling radiators, it's no big deal seeing it amongst the black components in my PC case. Actually, I kind of like having the 'official' Noctua fan color.

I purchased this because I'm using a medium case and wanted to ensure the heatsink wasn't too wide such that it would touch the side panel. This fit with plenty of clearance remaining.I used this with an i7-12700K and ran a brief CPU stress test. After a few minutes of the CPU being at 100% load, temp held steady around 60c.

I've been a fan of Noctua for over a decade, and I've had an NH-D14, an NH-D9L and now an NH-D12L. I've also got NF-P12 case fans that I've had for over a decade and they're still going strong.I was a bit dubious about this one because when my NF-P12's are running at 100% I can just about hear them, and that's at 1300 RPM. So when I looked at this and found out it ran at 2000 RPM when under load, I thought it might be a bit noisy and I may have to adjust the fan curve in the BIOS, because having a silent or near silent PC is very important to me.I should have known really, it's Noctua. This cooler runs silent at 2000 RPM and keeps my 5900X well in check. I have my 5900X undervolted using the curve optimizer with a setting of -17. I also set the thermal throttle limit to 74C, because I'm not having it that 90C for this CPU is fine, no matter what AMD say.For core heavy workloads I get around 4.3GHz all core which is what a 5900X should do, and in gaming where only a few cores are used, it fluctuates somewhere between 4.8GHz and 4.95GHz, which again is what a 5900X should do.All this with the CPU not exceeding 75C and the PC being silent.The only downside is cost, you pay for Noctua, but you are paying for quality engineering that applies to both the heatsink and the fan. It's just like buying an Aston Martin, you know you are going to pay for it, but you also know you are getting a top quality product.I don't mind paying for Noctua products, but Noctua prices aren't everybody's cup of tea.Noctua customer service is top notch as well. For example, in 2021 I'd had my NH-D14 for a decade and wanted to use it on my 5900X. Noctua sent me the AM4 mounting kit for free. So I could use my NH-D14 on my new rig, which I have done until now. The NH-D14 is quite cumbersome though and I'm glad I replaced it with this. I can now access the first M.2 slot without removing the cooler, and my GPU is now a lot easier to remove when I want to clean it. This NH-D12L also outperforms the NH-D14 and is silent under load, whereas the NH-D14 is quiet under load but not silent.

I normally have built systems from every aspect, including case and cooling solution. However, with desperation of wanting an upgrade to a 6 year old system, and some scarcity of sourcing parts, I opted for a prebuilt solution, that had a stock intel cooler on the i7-11700KF, on a ASUS B560-G board, within a ASUS ROG G15CE designed prebuilt/case. I am literally writing this after installing this cooling upgrade.I was doing research for possible solutions to my current situation. I saw some other user's ways of possibly adding a taller cooling tower, which one version meant cutting a hole in the side of the metal side panel case they had. However, my side panel is of the glass version, and that was not an option. I saw this week that this came out via an online article and writeup of this being released this week. Thankfully Amazon had stock and I immediately placed the order. I was not disappointed.It fits, and it cools much more efficiently than I had even expected. I ran some loads that I normally ran the device under, which were most likely thermal throttling the system as the system was spiking in the 90C/212F areas according to HWMonitor. I believe I am now not thermal throttling as we speak, with the temperature under same load now reading 84C/183F at max readings.This is a mind easing solution that I was weary of working at first for the height limitation of the cooling tower I thought I might run into. However, Noctua has hit this out of the park and has provided the prebuilt narrow cases breathing room and doubled the cooling thermal area, if not tripled the surface area as the stock cooler on a visual analysis of heatsink surfaces. My case currently, without spending money on another case or even considering AIO or liquid cooling, is small as it is. Much smaller than I imagined it when I purchased it initially. The cooling tower has enough gap, albeit small if by millimeters, between the top of the thermal heat pipe ends and the glass side panel, that there is no contact whatsoever.And finally, the second main reason, aside from thermal control as the primary, was to reduce the noise created by the constant needing to cool the smaller stock heatsink. For those coming along behind me, the stock cooler is smaller than 92mm of even the rear exhaust case fan. Having the cooling fans that are larger and quieter from this is so much better than ever before. Even at load, there was barely any noticeable fan noise, you might literally have to get down next to the case to hear it if you have it below your desktop surface. My older AIO system is now even louder than this now. I am very happy with this and very thankful for this new release. I didn't have to spend excess money on a new case or a new liquid cooling solution that this was able to help fulfill.As far as installation, the instructions were very detailed and the parts were very easy to identify. While I can see someone not experienced possibly being a bit overwhelmed by such a task of a swap that might cause worry, from my other experiences, this was such a breeze and easy to accomplish, that I feel that my son could do the swap.
