NF-A12x25 LS-PWM
The Noctua NF-A12X25 LS-PWM was designed to be used on the Noctua NH-P1 passive CPU cooler. However, this fan can be used as a case or heatsink fan with ease, as it features the same functionality and the bearing system as the rest of the NF-A12X25 series.
However, this fan will not be as good as the regular NF-A12X25 fans, it can’t be as it spins at a lower speed. If you want a NF-A12X25 fan that is quiet then this mode is for you, however, if you want a fan that will deliver a good static pressure and airflow then you might as well get the regular NF-A12X25.
The reduced performance when compared with the regular NF-A12X25-PWM is justified by what can only be called, “the quietest fan I have ever reviewed”. Not only that but this fan still generated a decent amount of static pressure to make it worth using on a radiator or a heatsink. However, the low-speed operation means that this fan should not be used while overclocking your CPU, as no matter how much technology and engineering a fan can have, it can’t break the laws of physics and thermodynamics.
"In conclusion, the Noctua NF-A12X25 LS-PWM is one of the quietest fans I’ve ever reviewed." (Bogdan Manolache, Tech-Legend.com)
