A new version of Speedfan is out. It's a handy little utility for accessing the sensor chip on your motherboard. It's very easy to setup and easy to run. IMO it's better than MBM in a lot of ways. It also gives you a readout of your hard drive's SMART feature and tells you whats going on inside. It will even give a readout on your HD's temperatures. If you have control of fan speed through the sensor chip you can now have the fan speed dictated by either the motherboard or even the hard drive's own temperature sensor if it is capable!
