Review on Fan for Arctic P12 SLIM PWM PST case, black by Wiktor Tasior ᠌

I put 3 on blowing behind the front cover of the case. At low temperatures, the rpm is ~400. It is not audible at all, the flow is sufficient. With heavy load, the speed increases to 1000 and only air flow is heard. It was not possible to spin up to all the declared 2100 rpm in real tasks, they are controlled automatically by the BIOS, depending on the temperature, it is necessary to make it very hot inside. Manually accelerated once, the air flow is noisy, the motors are not audible.
