"The other monitoring functions of the PC probe are just as reliable. The voltage readings for no apparent reason drop off the scale every 5 minutes or so with the +12V instantly falling to 4V or the -12V spiking to -3V! Fan readings crap out on demand and even send their fun errata over to the Hmon causing readings of 14,000+ RPM's. I am not a scientist or have a major on the laws of centrifugal force but I think that if any of the fans inside my case suddenly began spinning at 14,673 RPM's things could get real ugly!"
