Compact 110mm dual-tower cooler

The Noctua NH-D9L is a premium dual-tower CPU air cooler standing 110mm tall with a 92mm NF-A9 PWM fan. Its 95x95mm footprint and horizontal fan orientation deliver strong cooling performance while maintaining full clearance for RAM modules and PCIe cards on Intel and AMD platforms. The package includes NT-H1 thermal paste and the SecuFirm2 mounting system for Intel LGA1851, LGA1700, LGA1200, LGA1156, LGA1155, LGA1151, LGA1150 and AMD AM5, AM4 sockets.

Suited for space-restricted builds.

This cooler targets builders assembling HTPC, ITX, Small Form Factor or 3U server chassis where height is limited to 110mm. The 100% RAM and PCIe compatibility on mini-ITX boards makes it practical for dense layouts. Buyers who need higher thermal capacity for heavy overclocking should look at larger coolers instead. Systems requiring fan sizes other than 92mm will not match this mounting pattern.

110mm maximum cooler height decides fit

The single specification that determines compatibility is the 110mm overall height, which enables 3U rack compliance and fits cases with parallel airflow paths. At 531g weight with copper heatsink material, the NF-A9 fan runs at 2000 RPM standard or 1550 RPM with the Low-Noise Adaptor, producing 46.44 CFM airflow at 22.8 dBA or 36.84 CFM at 16.3 dBA respectively.

Questions about this item

Will the 110mm height and 95x95mm footprint fit my 3U chassis without blocking RAM or PCIe slots?

At 110mm tall and 95x95mm wide, the NH-D9L is 3U compliant and clears RAM and PCIe slots on all Intel ITX boards and most AMD ITX boards, leaving full access to memory and expansion cards.

Does the SecuFirm2 kit include the AMD AM5 offset mounting bracket, and how do I orient it?

Yes — the SecuFirm2 system supplies the AM5 offset bracket; install it with the notch facing the socket centre so the cold plate sits directly over the CPU die for optimal contact.

How often should I replace the NT-H1 thermal paste, and can I add a second NF-A9 fan later?

NT-H1 stays effective for years; re-apply only when remounting the cooler. The heatsink is dual-fan ready, so a second NF-A9 92mm PWM fan can be clipped on anytime for extra airflow.
