And it's able to control fan speeds according to the temperature of other components, helping you to reduce system noise. If you do not allow SpeedFan to change any fan speed and set all the speeds too low, then SpeedFan won't be able to avoid overheating.SpeedFan is a system monitoring tool that can detect and display your PCs fan speeds, motherboard and hard drive temperature, system voltages, hard drive status and more. When you have properly identified which temperature sensor is which, try to lower the speed of each fan and look at reported speed and temperatures. If you have a 'Local' sensor, and a 'Remote' labeled one, this usually means that 'Local' is the temperature of the monitor chip itself and 'Remote' is the temperature read from a 'remote' probe.

This means that the same chip, an ITE IT8712F, for example, might be connected to a sensor diode measuring CPU temperature on Temp2 and, on different hardware, it might be connected on Temp1.

The hardware manufacturers connect available pins to different temperature sensors basically according to the physical placement of components on the motherboard. Most of them use labels like 'Temp1', 'Local' or 'Remote'. Only a few hardware monitor chips do label their connectors with 'CPU', 'System' and the like. Please remember that hardware monitors are chips that do have some pins (small connectors) which should be connected to some additional hardware (temperature probes, thermistors or thermocouples) to be able to read temperatures. SpeedFan strictly adheres to available datasheets for each sensor chip. From Fan speed to total voltage, you can view any and all of the current fans.įirst of all, you have to identify which temperature sensor is which. When Speedfan is in an open window, you can see a whole lot more. When minimized, a temperature reading is showed on the button right of the desktop. The main viewing purpose of SpeedFan is to show its user what's going on with their machine. SpeedFan is a program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips.
