Examples are 'seek error rate' or 'calibration retry count.' In this way, you can also use SpeedFan to identify hard drives that could cause problems in the future. SpeedFan also monitors quite a few hard disk conditions. For example, SpeedFan can send an email or run a program if the CPU has reached a certain temperature. What is more interesting is the tool's ability to inform you or take measures when certain events occur. The tool enables you to change other settings of your motherboard, such as the CPU clock, but I would be very cautious with such features, because it is possible to destroy computer components this way. You can also use SpeedFan to adjust your fan speed, if your motherboard supports it.

Monitoring the hard disk temperature only worked after I started the tool as administrator. I assume that since Linux can let me control my fan, Windows should be able to do it too. Measuring the voltages and fan speed didn't work on my Dell laptop using Vista 圆4, even though, SpeedFan officially supports 64-bit systems with signed drivers.
