[gentoo-user] My CPU seems to run hotter with Gentoo as opposed to Windows XP

[Richard Watson]

Hi all, I've loaded Gentoo on a Compaq nx 6150 notebook which reports a
Intel (R) Pentium (R) M Processor 1.73GHz Stepping 08 CPU at dmesg.

For some reason the CPU seems to run very hot with a lot of fan activity
compared to when I boot XP, plus overall performance seems slow in
comparisom to XP with Gnome freezing for a few seconds on occasion as
though the system is stretched.

Does this make sense to anyone? Is there a way of cooling how the CPU runs?

Thanks, Richard

I had exactly the same thing on my Athlon-MP. The whole idea is that
Windows automatically scales mobile CPU down (mine to about 500MHz)
when it's not being used so the temperature drops down a bit. I have
configured powernowd to autoscale my CPU and it's working exactly the
same as on Windows now. You can try something like that. Try to find
something what has to do with intelistep (that's the name of the cpu
scaling engine from Intel AFAIR). Good luck!

You have to configure your system to scale down the CPU frequency when
idle. Read this Howto:

Btw, I recommend the simplest approach:

1. Build your kernel with the 'ondemand' governor and intel speedstep support.
2. Merge cpufrequtils
3. Set GOVERNOR=ondemand in /etc/conf.d/cpufrequtils
4. rc-update -a cpufrequtils
