Methods and systems for thermal management of hardware resources are disclosed. To improve the likelihood of the computer implemented services being provided, the systems may include information transmission topologies that are more likely to properly transmit operating point information (e.g., actual fan rates, rates at which fans are to operate, etc.) between management entities such as thermal managers and entities managed by the thermal managers such as fans (and/or other types of gas flow control components). By doing so, the system may be more likely to provide thermal management services as intended by using the transmitted information that is more likely to be accurate.

Current mode fan control and tachometer reporting design

In one or more embodiments, a fan circuit may be configured with an input of a first amplifier coupled to a revolution indicator associated with a fan; an output of the first amplifier coupled to an input of a second amplifier; and a power supply input of the second amplifier coupled to a first contact of a first connector. In one or more embodiments, the first contact of the first connector may be coupled to a first contact of a second connector to drive a resistive load coupled to the first contact of the second connector; a second contact of the first connector may be coupled to a second contact of the second connector to provide a reference voltage to the second amplifier; and the second amplifier may provide amplified signals to the first contact of the first connector based at least on signals received from the revolution indicator.
