The main viewing purpose of SpeedFan is to show its user what's really going in their machine. When minimized, a temperature reading is showed on the button right of the desktop. When Speedfan is in an open window you can see a whole lot more. From Fan speed to total voltage, you can view any and all of the current fans.

First of all, you have to identify which temperature sensor is which. SpeedFan strictly adheres to available datasheets for each sensor chip. 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) in order to be able to read temperatures.

Only a few hardware monitor chips do label their connectors with "CPU", "System" and the like. Most of them use labels like "Temp1", "Local" or "Remote". The hardware manufacturers connect available pins to different temperature sensors basically according to the physical placement of components on the motherboard.

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 a different hardware, it might be connected on Temp1. 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.

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 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.

Here are some key features of "SpeedFan":

· handle almost any number of South Bridges
· handle almost any number of hardware monitor chips
· handle almost any number of temperature readings
· handle almost any number of voltage readings
· handle almost any number of fan speed readings
· handle almost any number of PWMs

What's New in This Release: [ read full changelog ]

· SpeedFan 4.40 beta is online! Winbond W83667HG support has been greatly improved and preliminary tests show that on several Asus boards now more fans (including CPU's) can be controlled using SpeedFan. Let me know your experience. CPU identification has been greatly improved too and now all of the Tjmax values published by Intel should have been implemented. I need your tests and reports.
· Don't forget that you can upload your configuration by using this link. I would really appreciate if experienced users with nicely working configurations could find 30 seconds to upload their configurations to help other users.
