I have just got a Macbook Black Core Duo. I have installed CoreDuoTemp (http://macbricol.free.fr/coreduotemp/) , and Fan Control (http://www.macupdate.com/info.php/id/23137) . CoreDuoTemp currently reports my CPU temp as 40oC, while Fan Control reads it as 48oC. Which one is right? Can someone recommend me a program other then CoreDuoTemp that can sit nicely in my menu bar and just give me the temperature reading? Thanks.
