    Love the low PWM threshold, it’s super quiet, slightly audible at 80% and more. But it moves a lot of air at 40-60%. Used it with Noctua’s passive NH-P1 cooler on my AMD 5950x. It works very well, doesn’t really need to come on except during heavy workloads. Even though the P1 cooler is not rated for the thermal load of the 5950x, I am able to get 90% of the performance of the CPU.
