Is there anything cheaper for on/off fan setpoint temperature control than these snap-action bimetallic disc thermostats?

Maybe a single-chip IC in a TO-218/220 package that can be mounted on the heatsink to be monitored?
I understand there may be AC/DC voltage and current limits of a thermal management fan controller IC, vs this mechanical switch.
