Thank you. I use this for my intels, ddnt know that there was a PPC version, or is it universal !
It was PowerPC only long before it was universal. ;)

That said, if you don't have sensors in the CPU Temperature Monitor won't help.
 
As Erik said, temperature monitor can only read temperatures where sensors exist. On most G4 towers in OS X, the best you can do is the hard drive temperature. The MDD does have a temperature sensor on the CPU card. G5s have temperature sensors all over the place.

Ironically enough, even G3s have a thermal diode, but I've only ever been able to read it under OS 9 and depending on the program the readings can be all over the place.
