Abstract
Methods and systems for cooling computer systems, in which the computer system has a processor and a fan. An exemplary method includes: determining a temperature threshold for operating the fan at greater than low speed; determining a temperature of the computer system; and throttling the processor if the determined temperature corresponds to the temperature threshold for operating the fan at greater than low speed.
Claims13
A method for cooling a computer system, the computer system having a processor and a fan, said method comprising:
- determining a temperature threshold for operating the fan at greater than low speed;
- determining a temperature of the computer system;
- and
- throttling the processor, responsive to a pulse width modulated signal, if the determined temperature corresponds to the temperature threshold for operating the fan at greater than low speed.
1 more element
A computer system comprising:
- a processor;
- a fan operative to provide cooling airflow for reducing a temperature of the processor, the fan having a temperature threshold corresponding to operation of the fan at a speed greater than low speed;
- and
- a temperature-monitoring unit operative to determine a temperature of the computer system and to throttle the processor if the temperature determined corresponds to the temperature threshold for operating the fan at greater than low speed;
- and
- wherein the temperature-monitoring unit is configured to throttle the processor by providing a signal corresponding to a pulse width modulation output of the temperature-monitoring unit to the processor.
