iSlayer have released version 3.3 of its superb iStat Pro widget. This new release now supports the display of temperatures for the Intel based Macs. Prior to this release, an extra third party extension was required. I have used iSlayers products for a long time now, so this superb monitoring widget comes highly recommended. Of note, the tiny version of this widget, iStat Nano, was also recently upgraded to version 1.8, this also gives full Intel Mac support.
