About the C-Type CPU coolers

I love C-Type CPU air coolers because of a used Thermaltake Big Typhoon during the end of socket 939 days. Due to the platform jump towards AM3+ and TtBT’s incompatible mounting kit, I purchased a Noctua NH-U12P-SE2 CPU cooler. Years have passed and after I’ve started Hardware BBQ, eventually I got my hands on another C-type CPU cooler- the Noctua NH-C14S which I use regularly. While I prefer using the NH-U12S, NH-U14S and the NH-D15 to show the motherboard’s layout compatibility, NH-C14S is a good performer and a great CPU cooler to look at. Unlike CPU tower coolers, it made a good impression and also was a solid performer, but a limitation of mounting a single fan.

The NH-L12S CPU Cooler…

This is the Noctua NH-L12S, a smaller and slimmer version of the NH-C14S. While it maintains that low-profile look, it isn’t as low profile as many ‘pancake coolers’ like the NH-L9x65. it is bundled with a 15mm fan where you can install it underneath or over the heatsink.

The TDP limitation is somewhere between 95-Watts and 112-watts for mainstream CPUs and 165-watts for Skylake-X. Noctua has a detailed list of that which you’ll see in its specifications.

Packaging

Noctua’s packaging is quite an attraction in itself design to protect its CPU coolers and organize its tools and screws. Noctua bundles few things that others wouldn’t, such as NT-H1 thermal paste syringe, a Philips head screwdriver and metal brackets and backplate.

Noctua mentions in its specifications about its fan compatible extending up to 120 x 120 x 25 mm fans. It is bundled with NT-H1 thermal paste, a screw driver, a Low-Noise Adapter and a metal case badge.

The fans are interesting, its a slim profile 120MM PWM fan with its proprietary SSO2 bearing with maximum speed up to 1850 RPM and minimum 450 RPM without the Low Noise Adapter which reduces maximum speed to 1400 RPM.
