Got a Rock Pi 4C+ with the official heatsink and fan. This has only 2 wires. Is it possible to temperature control this fan by turning it on or off on a specific temperature?
Is it possible to control the 5V output on the GPIO, or can you control the fan output pins?
If not, can you connect it to 3,3V and control this?
The GPIO pins operates at a logic level of 3.0V and 3.3V iirc. If you want to operate this 5V fan, I suggest getting a relay module with minimum signal voltage of less than 3V, or just regular Arduino relay module with a level shifter if you don’t mind an extra module. Do not power the fan directly from the GPIO logic pins.
