When I turn on my computer my CPU temps go from the mid 20s and climbs up to 70 before I had turned it off (this is at idle). Also, when I go into my bios the motherboard doesn't show the pump or the fans even though they are plugged in and the fans are spinning.
 
Sounds like your pump isn't working then; I think it runs at a constant speed. I believe the pump has a 3 pin connector so it won't report speed but the radiator fan should unless it's been replaced with one that also has a 3 rather than 4 pin connector. Have you tried plugging the pump into a different header and/or measuring the voltage?
