ipmi-fan-control

A tool to control the fan speed by monitoring the temperature of CPU via IPMI.

Why

Our Dell R730 server's iDRAC is not works as expected. The fan always run full speed. And is very noisy, We digged but didn't fix out. So I build this to control the fan speed programmatically. And use RUST just for practice. Any contribute are welcome.
