Cooling comes from the NF-A9x14 slim 92mm fan, which pairs PWM automatic speed control with an included Low-Noise Adaptor: full airflow when your Ryzen chip…

Frequently Asked Questions

Will the NH-L9a-AM4 fit in my Mini-ITX case?

At 37mm total height it is built for ultra-compact HTPC and Small Form Factor cases. Check your case's stated CPU cooler clearance against that 37mm figure before ordering.

Does it block my RAM slots or the top PCIe slot?

No. Noctua's tailored footprint guarantees 100% RAM and PCIe compatibility on all ITX, Micro-ATX and ATX AM4 motherboards, so tall memory heatspreaders are not an issue.

Which Ryzen CPUs can it actually handle?

Noctua positions it for AM4 Ryzen CPUs and APUs with moderate heat load, naming the 5600, 4750G, 4650G and 4600G. Check Noctua's official compatibility list for your exact chip.

Do I need to buy thermal paste or an AM4 bracket separately?

No. NT-H1 thermal paste and the SecuFirm2 mounting system for AMD Ryzen CPUs and APUs are both included in the box.

How loud is it, and can I make it quieter?

The NF-A9x14 fan uses PWM for automatic speed control and stays whisper quiet at idle. The bundled Low-Noise Adaptor caps the top speed if you want it quieter under load.

What warranty does Noctua provide?

Noctua backs the NH-L9a-AM4 chromax.Black with a 6-year manufacturer's warranty. Refer to the product listing for current warranty terms in your region.
