Noctua NH-D15 chromax.Black, Dual-Tower CPU Cooler (140mm, Black)

My all-in-one cooler failed and I swapped it out with this and the results were absolutely amazing. I didn't even need two fans to keep my CPU at about 68C Max playing Hogwarts in 4K on my i7 8700K CPU. Idle is around 22C. I could put the second fan in but it would protrude and I couldn't get my front glass on with my particular case but luckily it's not needed with my usage. I guess if you're into overclocking and trying to squeeze every ounce out of the CPU you can use the other fan but for my use for 4K gaming it does great. I checked out a few different tests on line and there was about a 1C difference with 2 fans vs 1. And it's surprisingly quiet, especially for how much air the fan pushes. Most importantly, I don't have to worry about this thing failing like all in one coolers. After this experience to me there's just absolutely no reason in my mind to get an AIO cooler other than lights when this thing works so well. I gave up a little bling from the lights but I'm super happy with no more liquid cooler stress. I think it looks awesome. This thing is super high quality and worth every penny. Install was easy and instructions were clear and everything I needed was supplied. I highly recommend.

This cooler is so awesome. Temps are in par with the AIO that I replaced with it if not even better while staying quieter. I love the look just keep in mind that it may or may not be compatible to fit some cases. I had some trouble fitting the right fan and had to ditch it and replacing it with a Noctua 120mm fan. the ram made the fan poke way out had trouble closing the glass panel on my NZXT H9 Flow. The build quality is really good

First off, this cooler is a fantastic piece of equipment. You can tell the quality is top notch, from the fin design, to finish, to mounting bracket, to the CPU mounting surface.However, there a couple of "minor" issues:- Listed as 165mm of clearance required, but this doesn't count the front 140mm fan. Depending on your RAM height, you could easily need 180 to 200mm of total CPU cooler clearance to allow the extra fan to be mounted. I'm currently using this cooler in a Fractal Design Define C, so I'm running with only the middle fan- 140mm fan is not as quiet as I'd hoped considering Noctuas reputation. Once I go over a 60% duty cycle, you start to hear the fan motor/bearings pretty audibly. However, it is basically silent under 50% duty cycle.- The top of the fan just has a serial number on it, which isn't the most attractive thing. The Noctua label is on the side with the wire, which I wanted to face down so you don't see it.However, I still give the product 5 overall starts. I mean, it's one of the best coolers out there both in terms of performance and moutning system. I wish all Tower Coolers mounted this easily.Regarding temperatures, it keeps my Ryzen 3700X in the 70C to 78C range under extended Prime 95 load in a 24C room in the Fractal Design Define C case. This is with Noctura 120mm case fans. (2 front, 2 top, 1 rear) At it's stabilize maximums, along with a GTX 1070 running Furmark, it achieves this temperature range while all the fans being around a 60% duty cycle, never needing to kick into their 80C+ aggressive fan curve area. That being said, this case is configured for silence not maximum cooling, so other cases would likely do better.In normal day to day operation, it tends to hover the 40C to 60C area. Still getting used to tweaking the Ryzen 3000 settings, as it has aggressive voltage spikes and boosts by default, so I stabilized fan curves until it gets over 70C to prevent random rev ups. But I digress.Overall, this is a fantastic cooler and I would buy it again.

I bought this because my AIO cooler was starting to fail. I was hesitant about air coolers but liked the idea of easily replacing a fan if needed in the future. This cooler is amazing—super quiet, with temps around 65°C under full load. I initially tried installing a second fan, but my RAM clearance was an issue. Fortunately, the second fan is optional, and after testing, I found I didn’t need it.The packaging was neat, and the parts and instructions were labeled professionally. Installation was fairly straightforward—some components were a bit finicky, but that was likely due to my case size. Overall, it wasn’t difficult to install, and I’m really happy with the performance.
