There are two things that could still be investigated but the chances that it actually brings any improvement are very thin: * There is an unknown SMSC Super-I/O chip detected, with ID 0x1581. This chip may or may not embed hardware monitoring features, and may or may not be accessible by the OS. It is possible that this is where acpitz gets its temperatures, in which case we can't access it directly with a native driver. Anyway, on a laptop it will be rather hard to find the chip to read its top marking and identify it. * Your SMBus controller is not scanned by sensors-detect. Either kernel support is missing, or the firmware denied access to the OS. You need kernel >= 3.6 (or >= 3.2.30, >= 3.4.11 or >= 3.5.4 if using any of these stable branches.) > I was hoping to control the fan speed on my CPU by running fancontrol, but Why?

Most likely hardware or system firmware limitations, which is common on laptops. You can see that the system temperatures are exposed though a (virtual) ACPI device, which indicates that thermal monitoring (and thus most likely fan control) is in the hands of ACPI. You can't use the fancontrol daemon on such systems. As mentioned before, your best chance is to take a look at the firmware setup tool, and see if thermal thresholds can be changed there. If so, this should adjust the fan speed accordingly. Sometimes you can also change the fan speed profile directly. > When I run sensors it seems to be able to read my CPU temperature (I'm > assuming that's what coretemp-isa-0000 is).

Odds are that this isn't actually a quad-core, but rather a dual-core with hyper-threading.

Indeed. 511 being 0x1FF, the maximum value the driver can report, I would suppose that the thermal sensor is either missing or damaged. But this could also be a driver bug or a missing quirk for this specific model. Either way, this should be reported to the radeon driver maintainers. -- Jean Delvare http://jdelvare.nerim.net/wishlist.html _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
