your thermal doesn&#39;t poll.... make it poll like this:<br>echo &quot;2 seconds&quot; &gt; /proc/acpi/thermal_zone/THRM/polling_frequency<br>or wichever thermal zone is in /proc/acpi/thermal_zone. then verify your trip points in the same THRM directory but in the file trip_points. you should see something like this:
<br>critical (S5):&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 105 C<br>passive:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 76 C: tc1=3 tc2=1 tsp=150 devices=CPU0<br>active[0]:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 67 C: devices= FN1<br>active[1]:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 57 C: devices= FN2<br><br>in the eg passive means that your cpu is downclocked since it has passed 76 degrees C
<br>active [0] means that your fan is triggered to on<br>active[1] means that the fan is not triggered and it is shut down. <br>the critical point is when the system shuts down.<br>if the polling_frequency tweak doesn&#39;t work then you have another problem (eg i had to compile the fan and thermal module included in kernel since modprobing them would not start the fan). if it works copy the tweak command and put it in some init script (i put it at the start of /etc/init.d/xdm so that i&#39;m sure it loads after acpi, since that file doesn&#39;t exists without acpi loaded).
<br>then try installing kima if you&#39;re using kde and add the kima kmenu applet to monitor some things. you should be able to see that the processor hardly passes 60 degrees while thermal goes high till the passive point and over; if you monitor also the cpu load and freq you should be able to see how your processors reacts to programs. remember to also install the klaptopdaemon since is quite useful in controlling the cpufreq_utils governors and acpi settings. try also the laptop_mode-tools and see if they can help you have a better use for your disk. the last thing that you can also install is the hddtemp for monitoring your disk temperature.

Hi list,<br>&nbsp;&nbsp; i have a Santa Rosa (Core 2 Duo T7300) Acer AS5720 laptop, and i&#39;m<br>getting problems with the temperature of the CPU. In particular i&#39;m<br>using the coretemp module for determining the core temperature.
<br>Normally (using cpufreqd and the &quot;ondemand&quot; governor) the CPU stays at<br>nearly 50C&nbsp;&nbsp;(which i think is quite high since in windows , using Core<br>Temp it gives about 30C).<br>While compiling this increases up to 95-100C (after which it shuts
<br>down). The problem is that the fan is not spinning up at all!<br>What can be the cause of this behaviour? consider that i&#39;m using an up<br>to date system with gentoo-sources-2.6.22-r8.<br><br>Any help appreciated,
<br>Regards,<br>Marco<br>--<br><a href="mailto:gentoo-laptop@g.o">gentoo-laptop@g.o</a> mailing list<br><br></blockquote></div><br><br clear="all"><br>-- <br>dott. ing. beso
