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.

PROS•Its insanely quiet•Can cool an overclocked ryzen 7 5800x at 50 degrees and below•looks sick for all black builds•works flawlessly with AM4 and am5 CPU'sCONS•Only has 140mm fans no 120s•Needs a big motherboard for ram clearance11/10 will buy again

I built my machine about 3 months ago.. but noticed while the NH-9DL did a good job with the i7-9700K. If I wanted to overclock, it got a bit toasty and unstable. So I looked at a AIO, and after seeing LinusTechTips review of the D15 decided to go with it.A few things I wondered and soon found out:#1 - I have 64GB of ram and noticed the D15 was a bit large, but figured give it a try. As you can see it clears the Ram, BUT didn't clear the other heat spreader on the MB.. ( NOCTUA did say that the second fan may not fit.. )#2 - Although the other fan did not fit exactly where it needed it DID fit in the case about an 1" away from the fins.. and was a big improvement over the original case fan and was close to the intended location.#3 - If curious, YES the original motherboard mount for the NH-9D does work on the new fan so saved me that time and made install even easier.#4 - BONUS the 9D fan with the 15D springs FIT where the 15D Could Not !! So it was like having 3 fans on the cooler ;)#5 - ANOTHER BONUS - They give a number of extension cables for the Fans.. So I was able to mount the fans and get them all power.After doing all that.. I went and got to overclocking.. and stress testing.. I ran Cinebench R20, and custom set it to have 256 render threads to really stress the chip. I then ran them back to back to back until the chip wouldnt get any hotter.. ( an average of 6 times ).As you can see, the results speak for themselves.I went from :89 degrees C when stress testing it in Default settings...to64 degrees MAX when stress testing it WHILE IT WAS OVERCLOCKED !!I was MORE stable overclocked.. ! WOW and WOW and WOW.. Noctua hit it out of the park..As for how loud it is.. it is a LITTLE louder than just the 9D.. but I can't tell you exactly how much as its not a lot.UPDATE:I downloaded OCCT and ran its burnin test, and got to 75C after minutes of maxing everything. The amazing thing is anytime it got off the overclocking settings the CPU dropped back to 35C in a matter of seconds. So unless your both overclocked to 5.1MGZ AND using a LOT of hardcore video or 3D Graphic editing for hours, I think the D15 will keep your system supercool.I personally overclock for gaming, and I DO BIM and 3D Scanning, so I have to process GB size 3D Point clouds, and convert them to Mesh.. THAT does force my CPU to run 100% for a hour to process. BUT even then I never saw higher than 70 and was rock stable the whole time.So I guess what I am saying is custom water cooling MAY do a tad better, but HIGHLY doubt a AIO could do any better at all, and especially not at this cost point and if your upgrading from a Noctua 9 or 12 you can reuse the fans with all the extras that come in the kit here.

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.

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

When my AIO (less than 2 years old) started failing, my processor temps began creeping up...50C, 60C, 70C. It was my first AIO (and probably my last). My previous build used a Noctura NH-D14, and it worked flawlessly. So, back to something tried-and-true. Enter the NH-D15. In short, it's a beast, both in size and cooling! It somewhat dominates my be quiet! 500 case, sitting atop an AMD 9 7950X with just enough pipe clearance for all 4 DRAM sticks. The NH-D15 comes with a second fan for the front of the assembly, but there's no room in my current config so I'm running without it. The downside to the NH-D15: If components like DRAM or top mount fans need replaced, the NH-D15 has got to come out. Given the size of the NH-D15, I imagine this same challenge will exist for a number of other rigs. The upside to the NH-D15: It is ridiculously cool, aided by 6 case fans. Idle temps won't break 34C-35C even when ambient room temp is 75F or so - and that's with all fans in silent or standard modes which are nearly undetectable from a noise standpoint. When pushed, I have yet to see temps break 45C. Punch up the fans a notch (even then, the fan noise is very mild) and temps settle comfortably in the high 30Cs to low 40Cs. All-in-all, a GREAT CPU cooler!
