Data center cooling

A computer program product for automatically adjusting room temperature in a data center room, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code readable and executable by one or more processors to perform a method comprising:

• receiving, by a processor in a heating, ventilation and air conditioning (HVAC) system, a throttle threshold temperature for each of multiple computing devices, wherein the multiple computing devices are physically located within a data center room that is climate-controlled by the HVAC system, wherein the throttle threshold temperature is a temperature that, if exceeded, causes operations of one or more components of a computing device to be reduced, and wherein the throttle threshold temperature is provided by a hardware management module (MM) associated with at least one of the multiple computing devices;
• monitoring, by the processor in the HVAC system, a real-time temperature of at least one of the multiple computing devices, wherein the real-time temperature is provided by the hardware MM associated with said at least one of the multiple computing devices;
• and
• in response to the real-time temperature of said at least one of the multiple computing devices exceeding the throttle threshold temperature for said at least one of the multiple computing devices, decreasing an ambient air temperature in the data center room by adjusting a hardware thermostat in the HVAC system.
