@madbiologist: good info on the radeon open-source improvements, but the
OP is (was?) using fglrx on Precise. I'm marking this Incomplete because
it is dependent on the OP's specific BIOS, and it's difficult to tell
whether the overheating has anything to do with the OS without more
info, such as whether this happens on other systems (i.e. Windows).
@OP: As best I can tell, the Core i7 doesn't start thermal throttling
until 100C, and at that temp OEM's may just initiate ACPI shutdown. As
far as automating the switch to powersave based on temp, I'm pretty sure
that could be done with a script of some sort (and one may very well
exist).

Title:
Request: Scale back CPU and GPU to avoid notebook overheating
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I've found this happening an increasing amount since upgrading to
12.04.
When under heavy load my laptop has all fans at full speed but still
often reachs critical heat (on the hard drive I think) and shuts
itself off.
I think this is mostly poor hardware design but it would be awesome if
linux was able to detect dangerous temperatures, and if fans are
already on full, scale CPU and GPU operations down to reduce heat so
that a fatal shut-off can be avoided.
I have an HP Pavilion with Intel core i7 and ATI Radeon HD 5000.
I've installed indicator-cpufreq so I can manually control CPU frequency when
at high load. This seems to effectively reduce the temperature but it would be
good if the system could do this automatically.
