My fan work correctly.  It seems to have 4 level.  It stay on level 3
all the time making lot of noise, and when it reach 90 C it switch to
level 4.   (level 1 being 0 rpm)

I'll call Lenovo technical support tomorrow and until that
scaling_max_freq at 1200000.

thanks a lot,
Nicolas

&gt; Hi,

&gt; I bought a T42 a month ago, I've never experience overheating issue
&gt; until last week. Here the spec of my laptop:
&gt; T42 - 2378 RBF (I know, RBF does not exist on IBM site, but that's
&gt; what is written under it) 
&gt; Pentium M 1.7
&gt; 512 MB RAM
&gt; 80 Gig HD
&gt; I'm using ACPI with speedstep_centrino driver combined with cpufreqd un
&gt; Gentoo Linux. I don't have to explain that this was not a problem when
&gt; I first install my computer. Right now, a simple loop like: while true;
&gt; do true; done will overheat my CPU. The result is that the system shut
&gt; down on a critical temperature error ( 90-95 C) (note: removing
&gt; temperature module do the same result, but the bios shut down the
&gt; laptop, no the OS). When idle, at 1.7 GHz my cpu temperature is 69 C,
&gt; which is really high for a centrino. I had a DELL centrino 1.6 before
&gt; on which I compiled my actual Gentoo, it never become higher then 69 C
&gt; while compiling. I didn't find any temperature monitor on Windows, but
&gt; I observe that it becomes very hot and then scale down to 600 MHz and
&gt; then come back to 1.4 GHz and will never get full speed after.
&gt; 
&gt; I'm suspecting a hardware failure, but I just want to make sure,
