Noctua NH-D15S chromax.Black, Premium Dual-Tower CPU Cooler with NF-A15 PWM 140mm Fan (Black

I am using this for my Ryzen 5 3600. The stock wraith cooler was giving me 85 at full load and even a slight overclock hits the 95C. I live in a hot and humid environment.After using NH D15, at full load I am getting temps between 55 to 60 with precision boost applied. No load temps is at 37 to 45 (temp in Celsius). Nothing surprising . It definitely keeps 6 cores way below the max temp at full load plus giving plenty of space for overclock.

Haven't done tempersture tests yet, so this is a review just of visual checks and assembly experience.Solid piece of engineering. Well-designed with loads of fins, included 2 fans that can be fixed in whatever direction you want (depending on your case airflow direction). Came with all accessories, incl long screwdrivers, to be able to uuse for AMD and Intel mobos (last 3 generstions or so as of 2024). Peach-brown fans are Noctua trademarks, but ugly. Came with paste, just enough for 1 application.Overall, pricey, but great quality and well thought-out design.

Best in class

Using it on a Ryzen 9 5900x. Idle temps: ~45C (ambient 35C). Peak temps with moderate PBO: 76C. I'd recommend this over an AIO for long term, sustained usage unless you're an extreme overclocker.Pros:- Impeccable quality from Noctua - best in class!- Silent operationCons:- Received an unsealed, open box. This one's on Amazon- Make sure your case has 170mm of clearance or more if you want to mount both fans. With just the one fan 165mm is enough

So here's my in depth review of this cooler....see I'm more of a performance and reliability type of a guy so I bought this instead of a liquid cooler even though they're in same price range of 10K.and damn....I was surprised by the size of it and yes the quality it's not just quality it's QUALITY you can guess now.It's an air cooler so there might be a few temperature spikes bcz of flow of heat but that's not a problem bcz it's an air cooler but ones you start to play game OR under full load it won't go above like (in games like COD MW 2 and cyberpunk 60 65 ) and core work for like 70 highest that much I've noticed.... and so far I'm happy with it's performance and Yes I'm using a 5900X so it's a Powerful Beast and yes there's a little noise but not that much it's actually quite if you adjust the curves and yes you do need a lot of air flow for it bcz it's completely based on air flow so you will need a back case fan too.

You need a case that has a 140mm rear fan, to be able to use the second fan and most kinds of memory, else you won't be able to close the side panel.While the spec says 165mm, this fit my Phanteks P350X (specced at 160mm) just fine, the side panel does close - obviously with only one fan. However I am using this in a Deepcool CL500 with a Ryzen 3500, and I'm still not able to use the second fan because of my memory. With just one 140mm fan I'm getting about 3 degrees higher at idle and almost the exact same temperature at load as the outgoing Coolermaster 240mm AIO, with no attendant risk of pump failure or coolant leakage.Since I was using only one fan, I decided to skip the LNA. On the Chromax Black which I'm using with a 9900, I have both fans on the LNA so they are limited to 1200RPM. Without LNA, this gets up to 1600RPM and is still very silent. The clips do accept a standard 120mm fan, so I'm adding a Silverstone AB to get some additional cooling performance.The thing with these coolers is that they will last a lifetime, and Noctua support is beyond excellent. It seems expensive, but will outlast every other component in your system by a very long way. This is my second, with more to come, and I couldn't be more satisfied.I took one star off for compatibility, which remains a caveat with all twin-tower 140mm coolers.

Barely Any NoiseReally Easy to InstallComes with Two Noctua Fans with Total 4 AttachersCan be Arranged in Inner Flow to Decrease More Cpu temp n MosfetCan be Arranged in Outer Flow toDecrease Gpu and Ram Temperature as wellComes with Noctua nh1But Seems Arctic mx4 is still betterFins are Light WeightNo Worries for 15 yearsJust Only One Con but can be ignoredWhen Changing m.2 slot u will need to remove cpu coolee to access the Topm.2 slot or gpu needs to be removedIn some cases harder to remove gpu depends on motherboard

This just outperformed my single fan aio by a whopping 10 degree Celsius. However it's bit on the pricier side. But if it runs for a long time. This product will definitely last any future upgrades to the cpu. And would be worth the money.
