[ltp] Safe X60 temperatures?

Dear All,
What would you suggest are safe temperatures for an X60? I'm not
concerned about the surface temperature for now (I use the machine on a
table, but I don't want to hurt the hardware). At the moment:
* Without invoking tp-fan control, the system sits idle, with the fan
running, at about 42 degrees.
* With two copies of "nice yes > /dev/null &" running (one per core of
the T2500), but no manual control, I see sensors 0 and 3 hitting 90 and
89 degrees respectively (the fan is running at 3500 rpm, and the room is
at 20 degrees). The base of the machine is too hot to hold for more
than a few seconds. It seems stable for at least 20 mins in this state.
=> Is this normal (and safe), or is it hurting the CPU?
=> Does anyone make an egg-adapter, so I can cook on this? ;-p
* For normal usage, is it OK to ask tp-fan to hold it at below 65
degrees, (and only pass control back to the BIOS if the machine gets
hotter than that?)
* I want to submit this fan-control profile back to tp-fan; before I do,
does anyone know some better names for the sensors than 0-9?
Thanks,
Richard
