“SpeedFan”:http://www.almico.com/speedfan.php. This is an amazing utility. I’m going to donate to the guy who wrote it. It knows about the SM (system management) bus and the many different chipsets used. It can actually detect the temperature sensors used and the fan control. It can even dig down into late generation hard drives and tell you their temperatures.
The best feature is that it will automatically change the fan speed based on the temperature of the CPU, so that you get the lowest noise given the performance.
Motherboard Monitor does similar things, but there seems to be a bug where it can’t detect the temperature correctly or wattage correctly on my ASUS a7n8x.
