    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!

    You should be concerned when it reaches past 47c.
    You can open up the case (T10 Torx screws) and blow out the dust inside and on the fan within.

    Thanks! I think I'll err on the side of caution until I get myself a T10 driver to be able to do that. Any areas of caution to avoid (retained high voltage despite being unplugged, etc.?)

    And of course, I know not to touch the internals directly to avoid static discharge.

    It could simply be the fan vibrating loudly. I took mine out and lubed it gently and the sound was gone. Easy fix. Hope that helps.

    It's better to vacuum the dust from the inner components, then use compressed air to blow off the remainder. The fan will have caked-on dust so you'll need a T15 torx (larger than the T10 case screws) to remove the housing, and a small nylon cleaning brush to scrape the blades.

    My fan has been doing something similar, lately even without a lot of external heat, the fan comes one and off frequently. Nothing really has changed. Maybe there is more dust in the main system. I'll try and clean it out, but is there a temp sensor that fails or something else? Yesterday the MBT showed 42, today it is 36 and still has the same experience.
