I cannot reproduce this problem on an Acer Aspire 5315 with Jaunty, using either the stock 2.6.28-11-generic kernel or the updated 2.6.28-15-generic.

/proc/acpi/thermal_zone/TZ01/temperature seems to be very inaccurate (only ever says 45'C or 50'C) and I'm ignoring it. I installed lm-sensors and watched the output. When the system is idling it runs at 46-47'C. Running burnMMX it goes up to 57-58'C. The fan runs constantly in both cases on a low speed that is barely audible.

Perhaps there is a different hardware revision or a number of laptops have been made with poor quality or badly applied thermal paste (remember this is an extremely cheap and nasty laptop), or the heatsink is prone to get dusty?

cheers, chris.
