SpeedFan is a freeware application for Windows which allows you to monitors voltages, fan speeds and temperatures in computers with hardware monitor chips. If your PC hangs when under heavy load or after some hours of usage, SpeedFan might help you to find the real cause of the issue. SpeedFan can even access S.M.A.R.T. info and show hard disk temperatures. SpeedFan can access digital temperature sensors and can change fan speeds accordingly, thus reducing noise.
SpeedFan can access the temperature sensors available on your motherboard and on your nVidia video card. The most widely available temperatures are from the chipset, the CPU, the ambient and from the power circuitry.
SpeedFan monitor temperatures from several sources. By properly configuring SpeedFan, you can let it change fan speeds based on system temperatures. It is best that you manually configure the temperatures for monitoring and changing the fan speed instead of using preset values.
Based on the maximum temperature you set, Speed Fan will take up the warning and then increase the fan speed to maximum.
Speed Fan is an excellent tool to optimize and improve the performance of your hardware.
