If the fan -was- malfunctioning, it should show up in the BIOS. Apart from that, there are several programs that can measure modern fan rotation speeds. Look for "SpeedFan" or "Motherboard Monitor" on Google.

The large delay I am not certain about, but I could look into it if you want me to. Probably a network connection attempt timing out or something. The "Idle Process" is nothing to be concerned about. It is another word for "unused CPU time". Comp's doing nothing in that process.
