Overheating causing system shutdowns


Hello,

I have a Toshiba Satellite A505-S6965. My hardware is as attached via the Hardinfo report in pdf format.

Here is the most recent kernel error. It never says it is shutting down. It just "dies" even after saying the temp/speed is normal.

Code:
Jun 16 19:28:00 localhost kernel: [  845.153389] CPU0: Temperature above threshold, cpu clock throttled (total events = 1)
Jun 16 19:28:00 localhost kernel: [  845.153394] Disabling lock debugging due to kernel taint

From earlier in the day, I get this:

Checking sensors I get:

Code:
$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:       +66.0°C  (crit = +104.0°C)                  

coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +52.0°C  (high = +85.0°C, crit = +85.0°C)  

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +51.0°C  (high = +85.0°C, crit = +85.0°C)
I've never seen the Core 0 and Core 1 get 85+ in working with the system.

The above readings are what I'm used to seeing (sometimes around 60 if I'm working the cores).

Any idea what is going on and how to stop it?

I don't hear a lot of fan-control revving up like I used to before upgrading from Linux Mint Gloria (Ubuntu 9.04) to Linux Mint Helena (Ubuntu 9.10).

Not quite ready to do an upgrade yet as I need more time to set things up.

With thanks,
Narnie

A systems inner temperature depends on the external temperature
and the airflow. Set your laptop over a table and watch what
happens. I you have a fan, set it blowing to the machine. That
should lower the temperature. If it doesn't happens, then either
the fan is broken or the acpi system shuts it down.
In any case, overheating is generally caused by dust accumulated
in the air path and over the dissipators.
