i have an '87 camry heatercore (BA) with 2 x 120mm papst 100CFM's on it running thru a vantec nexus on dead low. the rad is always fairly 'cold'. the pump isnt inhibited at all, about 4" of tubing to the pump from the res. i dont have a multi-meter but i am looking @ getting one shortly, i must measure the current it draws. the tubing is all 1/2" ID clearflex60, with built in lime deposits which i still havent formulated a plan to rid myself of. however my girlfriend is a science student and she suggested bi-carb soda... not in my loop! i tried it on some tube i had cut which had been used and had the so called lime buildup, it seems to reduce it somewhat, probably needs some flow or some sort of scrubbing to work best.

edit : pump hasnt made any differenent noises since i got it, and its only just started getting warm.
