Re: CPU freq & core temp

Have you tried to use Gkrellm and gkrellm cpu freq plugin ?

It is not absolute temp. it seems 5-10 oC higher than real temp.

You may 1) change cpu heat think, and/or 2) get down cpu voltage(what do
you say, i forgot, but many PC vendors do not support this), and/or .....
But you can try '/usr/sbin/fancontrol' if you have fan noise other than
high cpu temp. cpu temp limit might be 105oC or so.
