Pros & Cons
Pros
- ✓ Dual-tower, 6-heatpipe stack handles overclocked Core Ultra and Ryzen 9000 chips
- ✓ Asymmetric offset design clears tall RAM and the top PCIe slot
- ✓ Single NF-A15 140mm PWM fan with Low-Noise Adaptor for near-silent operation
- ✓ 6-year Noctua warranty, unusually long for a CPU cooler
- ✓ NT-H1 paste and SecuFirm2 mount included; no extra purchase needed
Cons
- ✗ Brown-and-beige color scheme clashes with most RGB or blacked-out builds
- ✗ Ships with one fan, not the dual-fan setup of the standard NH-D15
- ✗ Dual-tower height can foul side panels in compact mid-tower cases
- ✗ Large air cooler adds significant weight to the motherboard vs an AIO
Manufacturer description
The Noctua NH-D15S takes the award-winning NH-D15 dual-tower design and shifts the fin stack off-center, so you get the same six-heatpipe cooling performance without sacrificing your RAM slots or top PCIe slot. That asymmetric layout is the whole point: tall memory heatsinks clear the cooler, and your GPU still seats properly. A single NF-A15 140mm PWM fan handles airflow, and the bundled Low-Noise Adaptor lets you cap RPM when you want a near-silent build rather than maximum thermal headroom. Noctua includes everything you need in the box, including NT-H1 thermal paste and the SecuFirm2…
SpecPicks Verdict
SpecPicks scored Noctua NH-D15S using a rating × review-volume × price-fit model applied to published specs and reviews across the cooling & fans category. Noctua's cooling & fans lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for cooling & fans of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
Will the NH-D15S fit with tall RAM?
Yes. The NH-D15S uses an asymmetric single-fan design specifically to improve RAM and PCIe clearance versus the standard NH-D15. Check your case and motherboard clearance specs for exact fitment.
Does the NH-D15S support AM5 and LGA1851?
Yes. The included SecuFirm2 mounting system covers Intel LGA1851, LGA1700, LGA1200, and LGA115x, plus AMD AM5 and AM4.
Can it cool a Ryzen 9 9950X or Core Ultra 285K?
Noctua lists both as target CPUs. The six-heatpipe dual-tower stack is rated for overclocking or near-silent operation on Core Ultra 285K, 265K, 245K and Ryzen 9950X, 9900X, 9700X, and 9600X.
How loud is it?
The NF-A15 140mm fan supports PWM for automatic speed control, and the bundled Low-Noise Adaptor caps maximum RPM for ultra-quiet operation. Exact dBA figures are on the Noctua product listing.
Do I need to buy thermal paste separately?
No. Noctua includes a tube of its NT-H1 thermal compound along with the SecuFirm2 mounting hardware, so the box has everything required for installation.
