FWIW, those that set their trip points too high deserve to fry their hardware. When notebooks
cost as much as they do and repairs, downtime and recovery of data is what it is, I'll gladly
wait a few more moments for a job/work package to finish and be confident that the notebook I
own will run for years on the OEM build hardware.

Any rule with electronics is that the cooler they run the longer their useful life. 65-70* C
would be unacceptable heat for a desktop, it's no different for a notebook and it's even a
bigger atrocity.

Apple had this issue back in 2003 with Powerbooks, they sent out updates and the fan turns on
in OS X Panther, Tiger and Leopard in my G4 @ 47* C at a lower controlled speed and if that is
inadequate to cool, as temperatures increase, the fan speed ramps up to higher rpm's. Linux
should behave this way as well in my opinion. The other options/solutions are to reset trip
points where the fan comes on @ 100% or have the trip point install in Ubuntu @ 65* C. I
prefer Apple's solution, but since this is Intel/AMD, resetting trip points is my preference.
65* C trip point is a forced option that makes me cringe to be forced to use on a Dell L400 P3
733 Mhz notebook.

BTW, that story about the hdd dieing, I had that happen when I first installed Ubuntu around
version 6.10. I researched trip point resetting and was pleased with the results through 7.04,
so much that I stayed @ 7.04 until earlier this week when I updated to 7.10 and now 8.04. I
was unaware this safeguard had ben implemented, had I known, it would've made a decision to
simply not upgrade the OS very easy for me. I may go back to 7.04, maybe as upgraded as 7.10 ?
As I did these updates back to back, I really didn't get to know 7.10 and how it behaved on
the Dell L400.
