PC-A77 features Smart Fan Control to control the fan speed automatically. There are total of 4 x 12cm fans, therefore it is a good idea to control the fan speed to lower the noise level. The fan speed will automatically adjust from 1020 to 1500 RPM by temperture difference.
PC-A77 used large size fans to improve the silent issue, there are two 120mm fans in the front and two 120mm fans at the rear feature low RPM with high air flow to get the best balance between silent and cooling.
There are anti-vibration kits fitted in the chassis to stop the vibration which cause the noise.
