Can I buy a soundproof box to stick my server in?
patio11: I think "my laptop is noisy" is the symptom, not the problem.  The problem is that you have a server in your bedroom.  You can address your problem by renting a cheap VPS or low-end dedicated server.  You'll never hear it or worry about temperature again, you'll have increased reliability, and you'll spend less of your valuable time keeping the server alive when you could be doing more important things.
