SpeedFan – Portable Fan Speed and Temp Control
SpeedFan is a system tool that can read the temperatures, voltages and fan speeds and check the status of your hard disk using S.M.A.R.T. or SCSI attributes in computers with hardware monitor chips. It can be used to change the speed of the fans in your computer to keep it from overheating. SpeedFan can be run portably from a USB device and requires no installation to the host PC. It is fully configurable and you can create custom events to automatically handle every situation. SpeedFan requires roughly 3.76MB of free space for portable installation.
