    Does it seem to work hard which in turn being kind of loud? Or is it usually silent? There doesn't seem to be anything wrong but it does seem like it's working hard

    Noticed the same. Seems like like the fan works hard blowing warm air out even when it's just sitting there.

    It will be on the ground - No air flow!

    Hmmm... this is the first I heard of the Mavic having an internal fan.
    :( one more thing to worry about failing!

    If the internal fan fails... how long will it take for the internals to cook themselves into failing?

    24 cores are bound to generate some heat, and sitting still is probably the worst on the internals, for heat.

    Yeah.... luckily when I start my drone, I sit on the ground only until I get GPS lock and then I start flying. Hopefully, waiting for GPS lock won't be too long of a delay, even if the internal fan fails.

    Of all the things that could go wrong on a Mavic, the internal fan is the last thing I'm worried about. I don't think I've ever had any kind of fan used to cool electronics fail. It's a little annoying when you're just sitting on the ground, but it's really not that bad.... and nothing compared to the noise the props generate.

    The Mavic seems to burn about a percent or so a minute just sitting on the ground. I wonder if the fans do come on in flight. The ESCs must get pretty hot in such a confined area, the heatsink does get hot to the touch sometimes.

    I've seen several electronics die due to a broken fan.

    24 cores might not necessarily mean more heat. Less load per core could mean they aren't being thrashed as hard. DJI did say there are a lot of sensors, etc so maybe some are used as "back up".

    Not trying to pick at comments or anything aha Just a thought when I read your comment

    The controller has fans to I noticed while upgrading firmware. No fans on either while flying though.

    Fan will sound like its working hard but it's just doing its job. There's a lot of data being transmitted through the FC and VTX generating a lot of heat which is being dissipated by the fan. When DJI moved to more reliable integrated VTX units starting with the Phantom 3 they began integrating a cooling fan.

    Have you seen any Phantom fan failures?

    My p3p had a terribly loud fan during updates but when it was in air it never had any issues. I had a battery failure but never even worried about the fan.

    None that have been known or reported. Unless you carefully listen for the fan every time you may not hear if the fan were to go out. Really don't think it's something you need to worry about.

    I turned on my Mavic for the first time and after only like 10 seconds sitting on the table and holding it in my hand it turned on the fan like on full speed, its a very loud fan sound.

    Can this really be normal? My Phantom 2 and my Inspire 1 definitely doesn't have this loud fans.

    There are several internal thermocouples monitoring temps which control the fan and it's speed. If the fan were to fail, the RC would give you a temperature alarm.

    Yes i guess you are correct about the fan, it would be worse if there were no fan, but what made me question it was that it seemed to go full speed from the get go, immediately, not like a computer fan that can run slower when the temp is not that high yet.
