I also have a 40GB GNX in my T22 and as nowadays most if not all these
disks are SMART capable, I am using DTEMP
(http://private.peterlink.ru/tochinov/download.html) to display the disk
temperature since last June.

These last days, I have a disk temperature up to 40°C(104°F) when the
laptop is idle (room temperature is around 20°C-68°F) which looks pretty
high.
(to compare, a 120 GB IBM and a 80 GB IBM in my desktop shows
respectively 27 and 26°C - ~80°F)
When doing a disk intensive work, like looking at a MPEG file located on
the disk or reorganizing/moving large files from partition to partition,
temperature goes up to 52-55°C (126-131°F) which is the max
specification for that kind of device.

OTOH, if I read a DVD, the disk stays around 45°C(113°F) only, so this
shows obviously that the high temps are a consequence of the disk
activity, not the CPU heating the disk.
 
Last summer, when we were hit by the heat wave, my PC crashed for the
first and only time as was using it.
I searched for a tool, found DTEMP and installed it.
 
Just after installing the DTEMP utility, I rebooted the T22 and the
DTEMP temperature went to 55°C(131°F) in a few minutes...!
(you can set a temperature warning which display a message on the screen
and beep the laptop.)
So I don't dare to imagine how high went the PC temperature when it went
to crash previously! (the room temperature was around 35°C(95°F) at that
time) 8-(

I think using such a tool (there is many tools like 'Motherboard
Monitor' than can manage the smart disk information but I found DTemp
being very tiny in memory, showing just a small icon with temp figures
in the systray) is a good way to avoid overheating problems as the
temperature concern is not only a CPU one!

I suppose that the cooling system in the T22 (never opened it but I
remind the T600's one) has been designed mainly to cool the CPU...

So, if some people here have a temp display in their Thinkpad, I would
be interested to know what they get as an average disk temperature when
the Thinkpad is idle for a while (half an hour or so).

Bernard
