Advertisements So early this morning, my mom wakes me up, saying the Tivo is making a lot of noise, and she asks me if she should unplug it. I tell her to do so. When I get up and plug it back in, it sounds like a jet engine. I unplug it for the day. We blew out the fan vent with compressed air and plugged it back in. As expected, it started out loud, then quieted town, as is normal for the boot process. It sounds normal now. If I reboot, it will be back to louder than usual. Right after the reboot, I checked the internal temp (MBT). It started out at 24, then 27, 29, 30 and 32. For the moment, it seems stable. I haven't seen it climb any higher. The Tivo itself seems to operate normally. But should I be scared? Is it a potential fire hazard? At what point should I be concerned over the internal temperature? I got it back in 2010, so I guess I shouldn't be surprised. But I also don't want to lose my content. Advice? Is it safe to leave plugged in at night? Or when we're not home? Thanks!
