You mean the fan on back of the box? Its working fine. Never had any problems in a lot hotter temps than now. I have the case slightly off, just enuf for a small gap at the front of the case, so any heat would have np escaping.

It happend again this afternoon, had to reset the tivo but wouldn't start up, so leaving it off for a while to see if that fixes it again.

Just going to have to start fresh with new image if its going to keep doing this, which in the long run isn't a bad thing as I'd be using a 120g instead of the 80g hdd it currently has, and if the 80g hdd health checks out ok I'll use that as a 2nd hdd for lots of recording time.
