Just as an addendum to this, I learned an expensive lesson about temperature changes in computers a few years ago.<p>I had a fancy Dell XPS gaming laptop and was at a LAN party with my friends, playing the latest and greatest. The computer was very hot to the touch. Well, it was time to pack up and leave, so I put my laptop in my flimsy backpack and took a 20min walk home in the freezing cold.<p>I get home and lo, the computer, ice cold to the touch, wouldn't boot. Took it to the shop and the tech said that a few of the components were cracked and i'd need to replace them or get a new laptop.<p>That's when it hit me; of <i>course</i> when you take something very hot and put it in something very cold, it's going to break. Should've waited like 5 minutes instead of rushing out...
