In addition, maximum fan speed can be reduced from 1600 to 1300rpm using the supplied Low-Noise Adaptor for even quieter operation. Officially, it doesn’t support two fans at the same time nor does it come with a second pair of metal clips. And to complete the performance conclusions, I would like to mention that I was expecting a bit worse temperature results bearing in mind the TPD capabilities of the cooler and the TPD performance of my processor. With CPUs rated at more than 100W of heat output, single graphics boards carrying similar ratings (and people want to run two!

For example, if a cooler uses a 140mm fan that overhangs the RAM and 46mm tall RAM modules are used, the max. Like all Noctua fans, the supplied NF-A12x15 features an MTTF rating of more than 150,000 hours and the entire NH-L12S package comes with a full 6-year manufacturer’s warranty.All of this at just 70 mm tall, with thermal results so close to a 160 mm tall single tower CPU cooler, like the U12S. Just like the original NH-L12 the NH-L12S features a total of four 6mm nickel plated copper heatpipes. Also when there is load on the CPU there are constant fluctuations in the revolutions of the fan but they are pretty smooth. Enough about the additional accessories, so let’s leave them aside until they are required and pay some attention to the cooler’s structure. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging .

Thanks to its NF-A12x15 PWM, slim 120mm fan, the NH-L12S provides even better quiet cooling performance than the previous model with its 92mm fan. For additional details regarding the cooler’s cooling capabilities please pay a lot of attention to the official TDP guide.Both SilverStone AP181 – 180mm fans were connected together to the chassis 1 connector and were rotating at maximum speed. The fan itself features a pretty solid square frame including the typical AAO (Advanced Acoustic Optimization), Stepped Inlet Design and Integrated Anti-Vibration Pads technologies combined with a 7 pretty narrow and at the same time very sharply angled blades forming the propeller working at 450(+/-20%) – 1850(+/- 10%) revolutions per minute range, with maximum airflow level of 94,2 m³/h at maximum noise level of 23,9 dB(A). identical 1mm thick with 2mm gap performance fins which are formed in a way to provide 3 cuts so a screwdriver can be used to fasten the bolts below the fins stack. Another airflow optimization comes from the staircase design for the frame which adds turbulence to the incoming flow, allowing a gradual transition of the flows.
