Mavericks temp variation

[Steve1812]

Installed Mavericks yesterday.

Today I noticed that the temperature was going from 41 degC up to 60 degC over a few seconds and as I type the temp is showing 33degC and varying by 1 degC every second or so. Now down to 31 degC.

Any thoughts?

Fan reports speeds varying in the 1390s range.

As I finish typing the temp has settled around 32 deg C. for the CPU 0 core.

With Mountain Lion never saw this kind of top temp and the core CPU ran around the low 30 degC in a steady temp room of about 15 degC - in a loft room.

If you're talking about CPU temperature, it's quite normal.

For more information I need screenshot of the main window + technical information from the about dialog.
