A custom designed Singularity Computers active PWM hub with high quality components and a dual layer PCB. The PCB and connectors are black with white logos and labeling. It has a PWM input which is split into 6 outputs. Only one of the outputs labeled FAN-OUT-1-RPM displays RPM so there are no RPM conflicts from the other PWM connections. The hub has an active PWM control circuit to adjust the speed of the connected fans based on the temperature of the coolant without the need of a motherboard. The potentiometer adjusts the PWM speed response to the temperature reading while a switch allows choosing between motherboard and temperature-based local PWM speed control.
