Do you have any evidence that seeking generates more heat than spinning?
Your reasoning seems sound, but my informal "finger testing" contradicts
it.  All the disk drives I have are the same temperature whether they're
idle or in heavy use, and among contemporaries the faster the spindle rate
the higher the temperature.   (The older 5" 3600 RPM drives are hotter,
but that's probably because the platters are larger and heavier, and put
more weight on the spindle bearings.)
