| description | To reduce noise by an operation sound of a fan while keeping cooling performance of the fan.SOLUTION: A cooling system comprises a fan 31 installed inside a frame 2 accommodating a CPU 10 referred to as a heating element, a temperature sensor 21 installed inside the frame 2, a temperature sensor 22 installed at a place different from the temperature sensor 21, and a fan control part driving the fan 31 when a temperature based on a measured value of the temperature sensor 21 is higher than a first threshold or a temperature based on a measured value of the temperature sensor 22 is higher than a second threshold that is set to a value lower than the first threshold.SELECTED DRAWING: Figure 1
【課題】ファンによる冷却能力を保ちつつ、ファンの動作音による騒音を低減することを目的とする。【解決手段】冷却システムは、発熱体として例示されるＣＰＵ１０を収容した筐体２の内部に設けられたファン３１と、筐体２の内部に設けられた温度センサ２１と、温度センサ２１と異なる位置に設けられた温度センサ２２と、温度センサ２１の計測値に基づく温度が第１閾値以上の場合、または、温度センサ２２の計測値に基づく温度が第１閾値よりも低い値に設定された第２閾値以上の場合に、ファン３１を駆動させるファン制御部とを具備する。【選択図】図１ |
