I learned a half a dozen computers ago it's good to blow it out with a leaf blower from time to time. It's not just build up on cooling fins and fans. That stuff can work its way into connectors and break the electrical connection.
Car wire harnesses have this problem and there's a buttload of engineering devoted to protecting the harness connections from a decade of vibration and dust working its way in.
