SpeedFan is an excellent one for monitoring voltages as well as cpu and board temps. You can set an audio alarm if the temps go too high, voltages rise or fall too far, and even set a threshold alert for fan speeds. That is a great freeware found at http://www.almico.com/speedfan.php
There are a good number of freeware/shareware sites to download free and free to try utilities for monitoring system processes as well as temps. Adding to that is a lengthy list of benchmark utilities. Here's a few sites to look over. http://www.majorgeeks.com/downloads11.html http://www.tucows,com http://www.geocities.com http://www.softpedia.com
