Abstract
An example system can include a noise sensor communicatively coupled to a controller of a computing device to dynamically determine a sound pressure level (SPL) of an environment in which the computing device is present. The computing device can include a cooling fan and the controller comprising a processor in communication with a memory resource including instructions executable to dynamically determine a threshold speed of the cooling fan based on the determined SPL of the environment set a speed of the cooling fan based on the determined threshold speed.
Claims15
A system, comprising:
- a noise sensor communicatively coupled to a controller of a computing device to dynamically determine a sound pressure level (SPL) of an environment in which the computing device is present;
- and
- the computing device, comprising:
- a cooling fan;
- and
- the controller comprising a processor in communication with a memory resource including instructions executable to dynamically:
- determine a threshold speed of the cooling fan based on the determined SPL of the environment;
- and
- set a speed of the cooling fan based on the determined threshold speed.
A method, comprising:
- receiving, from a noise sensor communicatively coupled to a computing device, a first sound pressure level (SPL) of an environment in which the computing device is present;
- determining a first threshold cooling fan speed based on the first SPL;
- adjusting a speed of a cooling fan of the computing device based on the first threshold cooling fan speed;
- receiving, from the noise sensor, a second SPL of the environment;
- determining a second threshold cooling fan speed based on the second SPL;
- and
- adjusting a speed of the cooling fan of the computing device based on the second threshold cooling fan speed,
- wherein the first SPL and the second SPL are different SPLs.
A controller comprising a processor in communication with a memory resource including instructions executable to:
- receive, from a noise sensor located on a computing device, a first sound pressure level (SPL) of an environment in which the computing device is present;
- determine a first threshold speed of the cooling fan based on the determined first SPL of the environment;
- set a speed of the cooling fan based on the determined first threshold speed;
- and
- responsive to coupling the computing device to a peripheral device of the computing device:
- receive, from a noise sensor located on the peripheral device, a second SPL of the environment;
- determine a second threshold speed of the cooling fan based on the determined second SPL of the environment;
- and
- set the speed of the cooling fan based on the determined second threshold speed.
