Temperature probe for Supermicro H12SSL-i

Hi,

I’ve recently built a water cooled server for my company based on the H12SSL-I board and I have a regular Flow/Temperature sensor in the loop. The flow sensor is easy, I can just put that on a fan header but for the temperature sensor (which is just a regular 10kΩ 2-pin sensor) I’m not sure, how or if I can connect that. The board does list support for an I²C temperature sensor, but I could find any hardware that maps the regular analog sensor to I²C, I’m not even sure if temperature via I²C is even a standard.

If I can get the temperature sensor into the BMC that would probably be best but otherwise getting it into Linux would probably also be fine since that’s probably where I’d set up some monitoring anyway.

The board is this one specifically: H12SSL-i | Motherboards | Super Micro Computer, Inc.

The control of the fans on that board isnt very good so whats the point of monitoring liquid temp? Just run pump at whatever speed you like then fans on full blast.

The point is to being able to monitor the temp with for example SNMP and make sure that everything is still working fine. Sure you can try and infer that via GPU and CPU temps, at least a bit, but I’d rather not take any chances and since I’ve got that sensor anyway.
