Hello! I'm use CCR-1036-12G-4S at home, and I am concerned about the fan noise of this device. I have 2 completely silent 1U SuperMicro servers Core i7 with 3 1U coolers and it is totally quiet. I don't understand why so noisy Mikrotik. My router cpu load 1-2%, but fan1-speed: 4030RPM : temperature:...
