Hi Mark, as said previously I don't have the same problem in my T400.

Have you tried using the latest BIOS? I have v3.12.

Something that might help: earlier this summer my T400 was heating up
to 60C idle (it was almost 40C air temperature), so I decided to open
it and replace the thermal compound with some high quality artic
silver. My idle temps have gone down by at least 8C just because of
that.

Regards,
Pedro
