I've relegated <gasp!> my TiBook 550 to the role of iMovie/iDVD/iTunes media creation/distribution hub, and, as has been discussed previously, when under load (say, pulling songs from iTunes in the living room and playing songs locally from iTunes - or just using creating a DVD with iDVD) the fan kicks on. While I would expect the fan to come on when the TiBook is compressing video in iDVD, I'd not expect it to come on when it's just playing and serving music via iTunes. I'm curious about any long term effects due to the fan running at high speed for several hours at a time, and what products y'all have used to keep your TiBook running cool as cucumbers. I put rubber feet (rubber?) on it several years ago - when I determined that the feet that came on it were...maybe not next to useless, but close. Supposedly they help with air flow, but I doubt they do very much. Save sitting it on an ice pack when creating DVDs, or only burning DVDs during the winter while sitting out on the front porch, what's a poor boy to do? Thanks! John (P.S. Don't tell me to "get a job"!)
