I havent found something like this that exists, in my mind, its simply a remote on/off and a PWM fan controller with an ethernet port.
I have a supermicro 826 chassis that uses the CSE-JBOD-PT2 board, the issue with this board is that it blasts all fans connected to it at 100% (and in my case, doesnt respond to physical power button presses). My hack at the moment is to use a PWM fan controller with a potentiometer to control fan speed and while it works well enough, I want the piece of mind of knowing that there is a fan controller that can ramp up if needed.
Shouldnt it be as simple as:
- using a relay, mosfet or whatever to switch power on/off
- thermocouples / i2c temp sensors (i2c multiplexer if needed, etc.)
- esp32 with an ethernet port
- some sort of logic for fan curves
The molex connectors have 5/12 VDC, so no need for PoE and the SM PSU will supply the 12V.
Does anyone have any criticism or advice/tips? Has anyone else done something similar?
