Under the case, where the fan expels hot air.

^^^^^^^^^^^^^^

Ah. With a docking station (or suitably cut piece of wood), the fan
on my T43 only comes on during boot.

thanks for that idea as well. that one seems quite doable and foolproof.

Probably the easiest way is to get yourself a usb 2.5'' sata case. Get
the old drive out of your laptop and put the new one in. Boot with a
live cd (knoppix, debian) and make the partitions to your liking on the
new drive. Then, mount both drives and do a cp -a /media/olddrive
/media/newdrive.
Finally, chroot to /media/newdrive, do a grub-install /dev/sda (or
whatever other device your new drive is mounted on), and check that if
you have a swap partition the pointers in /etc are still okay. When
done, reboot. If things fail, you'll always have your old drive as a
safe backup.

I should add that I am careful to (usually) use my ThinkPad on a flat surface
to maintain room for airflow underneath.

Yeah, I forgot to mention checking /etc/fstab.
