I think speedfan is great, it can adjust fan speeds automatically using your preferences, it can beep at u and pop up messages for different events (like "Your CPU is about to blow up...") all it takes is abit of customizing and it works wonderfully! why arnt u happy with it?
EDIT: just been looking at sensorsview pro, looks quite good, is the free download restricted in anyway? also can it adjust the fan speeds automatically? if not i'll stick with speed fan
