I want to, at a minimum, monitor my room’s ambient temperature, and the temperature of the air inside the case, and critically have those temps be fed to me in the standard ways other temps are (ie on linux lm-sensors).
Ideally the card would have more than one internal temp sensing cable, so you can attach them to various things, eg you could measure inflow and outflow temps at different fans, stuff like that. But at least one cable outside the case and one inside.
I visualise this as a PCIe card but there may be other ways you can hook into this that still let you provide the same temp monitoring interface without using a pcie slot. I also have no idea what I’m talking about, so could be using all the wrong terminology.
Is anyone aware of these kinds of addin cards? Does this exist?
