SpeedFan, like ALL 3rd party mobo monitors, just shows you the results from all the sensors it detects. Some of this can be bogus. YOU have to figure out which temp is from what sensor. Most mobos only have two sensors: case temp and CPU temp, so more than likely two of those readings are bogus.
From long experience I'd say Temp1 is the case temp which is about right (case temps in the summer are usually around 32C), and Temp2 is PROBABLY the CPU temp.
As for the fans, it will only detect the fan speeds if they're plugged into a header that sends the RPM sensor data to the mobo monitoring chip. Not all mobos monitor all FAN power sockets and not all fans have the 3rd wire for the speed sensor. Also you can't monitor the speed of a fan that's not connected to the mobo for power.
Almost every major mobo manufactuer today has their own temp/fan monitoring software you can download from their website (it should alos have been included on the CD that came with the mobo). Asus, for instance, has their Asus Probe software that works with ALL their mobos. Epox has one too.
Using the manufacturer's sensor application will be far more reliable than using a 3rd party app like MBM or SpeedFan. It will also correctly label the CPU and case temps for you.
Also, keep in mind that there is no accurate way to measure voltages except using a digital multimeter ($20 from Radio Shack). Don't rely on the voltages from the mobo's monitoring software - they're notoriously unreliable. Use them only as a guide.
