Nukecad - I have submitted a detailed response to the Ccleaner support team. The negative value doesn't bother me, it is just more for Ccleaner credibility that they should be able to report this correctly. Incidentally there is a Menu widget for CPU Temperature available in macOs, that gives what appears to be a correct value (32c this morning versus Ccleaner at -64c) Anyway thanks for your assistance

Thanks for the comprehensive response. I am running Ccleaner for Mac - Version 2.7.166 0n an iMac 27" i7. As I understand it the Ccleaner app always runs in the background and by selecting the "C with a brush" icon in the iMac menu bar (you can see it in the second screenshot above) you get the active cCleaner recommendations at the top. You can also access the Ccleaner settings from that screen. Whoever in Ccleaner designed this has obviously decided to display some system monitor type information , most of which makes some sense but not the CPU temperature being negative. Maybe someone from Ccleaner will pick up this observation and perhaps resolve, or remove if they can fix, the CPU temp display functionality.

yes, osMac version running on Ventura 13.2.1

Nukecad, I am running CCleaner Version 2.7.166 so apologies if I am exposing your ignorance of CCleaner functionality, as it is a genuine CCleaner screenshot of a sub menu, taken from the Menu Icon that appears on the iMac main screen (at least when running this version on MacOs Ventura). The primary CCleaner window that opens when the CCleaner icon is pressed gives you this screen, just click on Sensors to get the one I posted. This evening I have a CPU temp of -76c: Why not give it a try on your Mac and see what CPU temp you see?

Noticed this when I first installed Cleaner a month or so ago, and it always gives the a negative CPU temperature - today it is -65c (see screen scrape). Doesn't really bother me, but can't be right can it?
