Thanks wolfman, I had read that earlier, and of course the only action to take is 'get a heat sink', which I already have, and it still is getting hot enough to destroy data. I think this is still a new issue, so there isn't a whole lot of info yet. It appears to be hit and miss on getting a Pi3 that will heat up like this. Some are only getting up to 60Celcius, while others are hovering around 82Celcius, and then there are ones like mine that are getting 100-105Celcius. 85Celcius is supposed to be the throttle and 125Celcius is the max rating before failure. Of course, that doesn't account for the data destruction shutting down the whole thing first.
I've had to install UbuntuMATE twice, due to the data being destroyed by heat. That's just not acceptable. If it ends up that there are just a few faulty Pi3 out there, I'm fine with that, and I'll probably buy a replacement for $35. But if not, I'm getting another Pi2, until they sort it out.
Right now, if anyone asked me, I'd have to suggest getting the Pi2, for now, and waiting to get the Pi3.
The Pi3 is much faster, but not so fast that it is capable of more tasks. So yes, it is faster, but can't necessarily use that speed to perform functions that the Pi2 can't.
I really hate to speak ill of Raspberry Pi, they gave us such awesome, affordable tech. They produced many more of the Pi3, and they were selling before they were on the market. I hope that didn't rush them to put out a product before it was ready.
Even with this Pi3 being a problem, I will still be a Pi customer. If the Pi3 ends up a bust, I will buy another Pi2(since my friend borrowed my Pi2, and won't give it back). If they fix the Pi3, I'll buy another one(and maybe another two).
