Macbook CPU & Fans

Got a mail from Robert this morning with a handy app for controlling the fan speed of my Macbook, with a little playing I've found a good balance but then I noticed that there is a difference in the temps displayed by CoreDuoTemp which I've been running for a while and the new smcFanControl

Either way it's good to know what's going on and now even better to be able to do something about it !
