Frequently Asked Questions

Will the NH-L12S fit in my ITX case?

It needs 70mm of CPU cooler clearance with the fan on top. If your case lists less, you can mount the fan underneath the fin stack to drop the cooler to 51mm. Check your case spec sheet for its stated CPU cooler height limit.

Does it support AM5 and LGA1851 out of the box?

Yes. The included SecuFirm2 kit mounts to Intel LGA1851, LGA1700, LGA1200 and LGA115x, plus AMD AM5 and AM4, with an offset mounting option for better efficiency on supported sockets. No separate bracket purchase is required.

Is it quiet enough for a living-room HTPC?

The NF-A12x15 fan runs PWM speed control, and Noctua bundles a Low-Noise Adaptor that caps maximum RPM for ultra-quiet operation. Reviewers rate the cooler 4.7 out of 5 across 1,922 ratings, with noise a recurring reason.

Can it handle a Ryzen 9 9950X3D or Core Ultra 9 290K?

Noctua lists both the Core Ultra 290K/270K/250K and the Ryzen 9950X3D/9900X3D/9800X3D/9700X/9600X as target CPUs for this cooler. Expect a 70mm low-profile cooler to run warmer under sustained all-core load than a full tower.

Do I need to buy thermal paste and a warranty separately?

No. NT-H1 thermal paste ships in the box along with the SecuFirm2 mounting hardware and the Low-Noise Adaptor, and Noctua covers the cooler with a 6-year manufacturer warranty.
