So the issue is that when they lose their internet connection (ie, switch or dns fails or it runs out of backup pools) the chips stay on for some reason? Eventually burning up the hardware?
Are there other symptoms? Like, the unit is on and not responsive to pings or the WebUI is not accessible?
If so, this is troubling because we host a large number of S5s that are super finicky, they randomly just stop working even with stable networking and power and require a hard reset and costs me a lot of man hours resetting these things. Also, this behavior does not seem to be heat related.
Lets start a list of firmware versions that this is happening with.

how is everyone making money; with a difficulty of 2% 475 startup costs with a s4 and 2000 hash rate I'm showing break even after 176 days at current price. the business electricity is 0.03/kwh where I am now
You have a 200% ROA and you're not making money??
UPDATE:
I got quick response from BITMAIN, unit is on the way to the service, so they will take a look, but the thing is that they know about this issue, so i guess that i will get replacement unit in no time.
So far their customer service is really good... Will update as soon as I get some new info.

After missing interenet I broke 4 piece S5 of the ordered 11 pieces.

What? We have an epidemic on our hands! Our S5's are burning up! We're going to be making 0 if we lose internet and we'll never break even with bugged hardware!
Bitmain....fix that! 
I'll cut the blue wire on my S5s fan first thing tomorrow morning...
It's a little annoying if I have to sell them in the future, but I prefer that than the risk of frying them! I'll make an adapter for my next S5s (Material's coming in 3 weeks... !)

Don't cut it. If you have a small straight screwdriver or a good knife, it's really easy to lift the retainer clip on the plastic connector and just slide the whole pin out. Fold the wire back and tape it down to the cable or something so you don't risk grounding it on anything and turning the fan off, but then to put it back to stock all you have to do is slide the end back in the plastic housing. Completely non-destructive and completely effective.
Awesome! Works like charm. Thanks for the hint.

I have the same problem with S4+ units. If they lose network connectivity, they lower fan speeds to about ~1500RPM and start boiling. There was some incredible heat coming out of those boxes when I power cycled them. Thankfully they didn't die, but they certainly shortened their lifespans and burned a lot of electricity for nothing.
Come on, BITMAIN. Stupid stuff like this shouldn't be an issue after 10 hardware releases.

Today I was installing a few S5. In the process I connect one by one... but the power supply is ON. I note that the miners who are ON but without ethernet wire was getting hot.
This is a big firmware flaw!!
My S5 have 4 weeks old.
Take care, and add 2 or 3 pools.

One thing is on my mind atm.
Since BTCGuild will shut down on 1st of July, and of this is regular issue for the S5 Miners, since there are still 6500 TH/s on BtcGuild 1 day from shutting down, what will happen if some or majority of those miners are S5s? Are we about to see many of similar topics in the next few days, since technically all of them will loose connection to the pool? Hope not...

I can confirm this issue on my units as well...I have the fans connected directly to power though, but heat still insane. I think the chips are still powered but not hashing, so they are essentially 100% heaters.
This is a huge firmware/design flaw...not sure why bitmain has not fixed it yet...

So when it loses the internet connection the mining stops and the fans stop also? Is that how it works? On the S3+ when the internet is out the fans just slow down they don't turn off.
Not sure if I see just dust or cobwebs? Wonder if this contributed to the problem?
It shouldn't heat up if it looses internet connection, it makes no sense. I guess that unit goes into some kind of loop... But why besides that it didn't shut down >80c is beyond me...
Here are some pictures of the miner:
U can clearly see that the plastic cover has bent due to excess heat:

I bought 2 s3s for $300 with 2 power supplys was it a good deal? I could have maybe bought the s5. do I need a router with bridge of any speed to get them mining?
the previous owner of my 2 s3s told me he had no problems for 2 years.
You were lied to. The S1 didn't even exist two years ago. AM Blades and, technically, the first few BFL units were just starting to move.
wow that's a serious issue, is a firmware upgrade going to fix the temp shutdown? or maybe you need a fan or thermal cooling paste?
the previous owner of my 2 s3s told me he had no problems for 2 years. is the price of bitcoin going to go up?
