Problems solved by technology

Therefore, potentially harmful noise levels are a drawback of modern computer systems with conventional forced air cooling systems
The noise levels generated by computer systems have prompted the creation of safety regulations that limit the amount of noise these computer systems are allowed to generate
Unfortunately, limiting or reducing the amount of airflow through a computer system requires reducing processor load, thereby causing the computer to run below its full processing capacity

Embodiment Construction

[0016] The present invention relates to detecting the presence of a person and controlling the sound level generated by a computer system in response to the detected presence of the person. The present invention generally includes embodiments that automatically control sound levels in a computer room, as well as embodiments that automatically control sound levels near a particular component or group of components of a computer system. If the sound level exceeds a predetermined set point, the computer system enters a noise reduction mode. In the noise reduction mode, airflow through the computer system chassis or through a particular electronic component or group of electronic components may be selectively reduced by, for example, reducing the rotational speed of a fan associated with one or more components. If it is determined that the reduced airflow poses a risk of overheating the component(s), the temperature of the component(s) can be monitored and processor load reduced. ...

Abstract

Methods and systems are provided for controlling sound level of a computer system within a selected zone. In one embodiment, the sound level within an enclosed space is detected and an electronic signal representative of the sound level is generated in response. The presence of one or more person within the enclosed space is detected, and an electronic signal is generated responsive to the detected presence. The airflow rate and processor load are both decreased in response to the detected presence when the sound level exceeds a predefined sound-level setpoint.

Description

technical field [0001] The present invention relates to controlling noise generated by computer systems, such as rackmount server systems. Background technique [0002] Computer cooling systems can generate sound levels sufficient to damage hearing with sustained or repeated exposure. Rackmount server systems (eg, blade servers) can be particularly noisy due to the combined use of multiple servers and fans. As technology continues to evolve, servers are becoming more powerful and dense. Increased power consumption generates more heat, which requires more airflow to cool effectively. More airflow generally translates to higher noise levels. Potentially harmful noise levels are therefore a drawback of modern computer systems with conventional forced air cooling systems. The noise levels generated by computer systems have prompted the creation of safety regulations that limit the amount of noise these computer systems are allowed to generate. Unfortunately, limiting or red...
