I replaced the fan in my Thinkpad x60 Tablet (the thing I do all my art with) yesterday.
The good news: It now has a quiet fan!
The bad news: It totally no longer responds to any pen input at all. *facepaws*
After much frustration, and many more takings-apart, I just ebayed a slightly newer and more powerful Thinkpad x61 as a replacement.
Luckily I have my old x41 as a backup to hold me over until it arrives. I can draw with it just fine, but doing the super-huge CF comic might be an... interesting experience after layer 100 or so...
