I had this problem last year with a non-Thinkpad laptop. Opened it up and found the fan was dying, and barely working. I cleaned it out, got a new fan and some thermal paste for a total of $15 off of ebay, and since then it has run in the range of 35-60 degrees. Money and time well spent, as the laptop certainly would have experienced premature part failure at those high heats.
