Abstract

See full text

An information handling system uses one connector for both liquid and air cooling and detects the type of cooling system installed. That provides the ability to choose the correct thermal handling table based on the installed cooling system. To detect the type of cooling system installed, a thermal management controller sets a control signal supplied to the cooling system through the connector to a first control value and determines if a tachometer signal supplied by the cooling system to the thermal management controller through the connector indicates a first type of cooling system. If the first type of cooling system is not detected, the thermal management controller checks if the tachometer signal from the cooling system with the control signal set at the first control value, or alternatively at a second control value, indicates a second type of cooling system. If no cooling system is detected, an error condition exists.
