Anyhow it's working fine now Thierry Perhaps the explanation is that the software in Squeeze didn't detect the overheating and therefore didn't report an alarm. Upgrade to Wheeze fixed the problem. Just a guess. To verify you need to downgrade (not recommended) and somehow put the dirt back on the fan (is this possible?). IMHO, you should leave well enough alone. -- Paul E Condon pecon...@mesanetworks.net -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Thierry I must add: top gives the cpu working at 1 to 2 %, and it's really overheating, one can fill it just putting a hand on the keyboard.

If your computer rests and the CPU governor is set to performance, than the CPU anyway will be used at maximal clock. If it's set to another governor e.g. ondemand, than the CPU will run full throttle if needed, but with lower Hz when not needed. It's als possible to use the CPU at a fixed rate, e.g. a 2 GHz CPU could permanently set to run at 1 GHz. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Now what will cpufrequtils do?
Advocates and prospective users of cpufrequtils may benefit from reading
the threads starting at
http://lists.debian.org/debian-boot/2012/06/msg00679.html
and
http://lists.debian.org/debian-boot/2013/03/msg00189.html
Two selective quotations from Ben Hutchings' mails:
1. cpufreq drivers are now auto-loaded and te default governor is
ondemand, so most users won't need cpufrequtils installed any
more.
2. cpufrequtils should not be needed, as the Linux kernel in wheezy
is supposed to enable frequency scaling by default.
Please can you temporarily remove cpufrequtils ('apt-get purge
cpufrequtils'), reboot, and send the contents of:
/proc/cpuinfo
/proc/modules
/sys/devices/system/cpu/cpu0/uevent
/sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
/var/log/dmesg
Following the last piece of advice seems appropriate for anyone in doubt
about the effectiveness of the ondemand governor.
