With the fan mounted underneath, in low-profile, stealth mode, the NH-L12S stands only 70mm tall; Noctua themselves admit that cooling performance is diminished somewhat in this configuration due to a lack of airflow onto the PCB surrounding the CPU and associated power delivery.
There are 4 heatpipes to carry heat away from the CPU, however they aren’t direct-contact like many CPU coolers.
The top of the cooler features 3 small holes which line up with the mounting system, further aiding that ease of installation. The 4 heatpipes help distribute the heat evenly across the fins.
The fan can be mounted above or below the heatsink, to aid in clearing taller RAM or MOSFET heatsinks etc.
The heatsink can also be orientated in 4 different directions to keep the heatpipes out of the way.
You can see from this angle that Noctua has designed the fan-clips to accommodate 15mm and 25mm fans with the stepped bracket.
The NH-L12S uses Noctua’s SecuFirm2 mounting system, relying on two sprung screws; these screws aid in distributing the load onto the CPU surface increasing the direct contact between the CPU and the heatsink.
