Full-tower computer cases may contain multiple cooling fans. At the top of the case is a fan controller. Fan control is the management of the rotational speed of an electric fan. In computers, various types of computer fans are used to provide adequate cooling, and different fan control mechanisms balance their cooling capacities and noise they ...
SpeedFan is a system monitor for Microsoft Windows that can read temperatures, voltages and fan speeds of computer components. [3] It can change computer fan speeds depending on the temperature of various components. [1] [4] The program can display system variables as charts and as an indicator in the system tray.
Where noise is an issue, larger, slower-turning fans are quieter than smaller, faster fans that can move the same airflow. Fan noise has been found to be roughly proportional to the fifth power of fan speed; halving the speed reduces the noise by about 15 dB. [22] Axial fans may rotate at speeds of up to around 38,000 rpm for smaller sizes. [23]

However, laptop CPU fans are usually smaller, so may not necessarily be quieter than their desktop counterparts - a smaller fan area requires faster fan speeds to move the same amount of air. [51] Furthermore, limited space, limited access and proprietary components make silencing them more difficult.
