Noctua NH-L9x65 CPU Cooler Review: A New Low-Profile King

Closer Look at the Noctua NH-L9x65 »

Noctua NH-L9x65Certain limitations are obvious for vertically-challenged heatsinks such as limited thermal management capability but their small size allows for a more flexible compatibility when it comes to fitting in tight spaces. This is why the stock Intel CPU cooler is the default go-to cooler in a DIY SFF/HTPC with its 45mm height.

Unfortunately, it is generally louder and not particularly good at its job as well. In fact, the bundled CPU cooler on the Intel Core i7-4770K is not enough to prevent the CPU from reaching max temperature and throttling during summer conditions. Noctua answered this demand previously with their NH-L9 series that is better than the one Intel provides at a scant 37mm height, possibly the lowest CPU cooler available and can fit in any case. Those looking for a highly compatible heatsink but also want more thermal headroom however, were not satisfied with its performance.

Luckily for everyone, Noctua was not satisfied either, as they have developed a 65mm tall version of the NH-L9 that improves performance without going outside of the 95×95 clearance. The NH-L9x65 is essentially a 65mm version of the NH-L9 and adds two more heatpipes to curb the rise in temperature under load. The NH-L9x65 utilizes the same NF-A9x14 fan that the NH-L9 uses and can be controlled via PWM or installed with the bundled low-noise adapter.

As a premium brand, Noctua takes no cost-cutting measure even when it comes to the NH-L9x65 packaging. The outer packaging is a full-color glossy box that is surprisingly larger compared to most low-profile heatsinks.


Inside, the mounting accessories are housed in a labeled box while the bottom compartment houses the NH-L9x65 heatsink itself with the NF-A9x14 fan pre-installed with wire-clips and protected on all sides by multiple layers of folded cardboard (which explains the larger box size).
