Therefore, Noctua cannot accept any liability, nor in any other way be held responsible, for the following compatibility information.

Noctua NH-L12S Low Profile High Performance CPU Cooler Noctua NH-L12S, Low Profile CPU Cooler, Intel/AMD, Single NF-A12X15 Fan, 450-1850RPM, 55.and when it is used with the fan the maximum airflow level that NF-A12x15 PWM can achieve is 70,8 m³/h with noise level of 16,8 dB(A). With its single NF-B9 PWM 92mm fan, the new Ghost S1 edition is tailored for use in this case and has been updated with the latest SecuFirm2™ mounting hardware for all current mainstream sockets, including Intel LGA1200, LGA115x and AMD AM4, AM5. Version 2 uses metal bearings and thanks to better technique in the field of injection molding, the magnet is closer to the axis of the rotor.

The NH-L12s however, managed a more impressive (although to be expected considering the size) 20 delta on fan control mode, and 14 degrees under 12V mode. Another example being the i5 13500 system I just built in a FD Ridge with a Thermalright low profile cooler.

I found no weird aural annoyances during testing, with both fans showing a better noise profile than any fans I’ve tested in their form factors. The coolers that use 120 mm fans clearly show that they cool better hence why they take the advantage. Passionate about testing and reviewing, AMD overclocking using AM3 990FXA and AMD FM2 A85X test systems and building modding projects. Well, at load, the NH-L9a-AM4 reached a 35 degree delta over ambient during the fan control mode, and a 30 degree ambient under 12v mode.
