There's also SiSoft's sandra that does fan speeds I believe. I don't regularly use programs like these (only when Im messing with the fans or feel something is wrong with my PC) but Everest was good. I think they've stopped doing a free edition now though.
well i have 2 case fans, one is connected using molex, and the other one is the 3 pin thingy on the mobo... asus probe and speedfan wont detect it tho
