i had assembled a dual rad setup which i though to be excellent based on the temperatures i was receiving with the onboard sensors. i was unsure of the accuracy of the sensors but i was able to fine tune the whole setup till i get the absolute lowest temperatures. I was receiving 29c idle and 36 celsius load Via the onboard sensors. again i do not know how accurate the sensors on the asus k8v are. it turns out that i decided to disassemble my system and change various aspects of it. so i hooked uop an old koolance exos unit while i worked on it. My motemperatures are actually lower with the koolance than with my other system! both idle and load are lower. i idle at about 28c but i load at about 33 with the koolance. i know i was going for low mnoise with the yate loon quiet fans but i installed 2 radiators just so i could maintain low temperatures. i guess koolance isnt bad after all
