Noctua NH-L9i Low-Profile CPU Cooler Review

Noise Level Results




With the PWM controls turned off, and the L.N.A. in place, the NF-A9x14 PWM fan registered at 30 dB of noise with 12V set as being supplied to the connection, then it is reduced by the L.N.A. to 7.5V to achieve this result.




Removing the resistor and keeping the BIOS set to still deliver maximum voltage to the connection, all I was getting was an ever so mild hum coming from the cooler and registering at 41 dB for this test.


This is why I said there really is no need for the L.N.A. to be used, but it was nice of them to include it as an option on low TDP CPUs, where silence is important.
