I'm switching over to a kanthalbuild which has a lower powerlimit? and see if that makes any difference, I switched to nickel just the other day... the sensorlimits explains my randomness so that's good to know

How do you have the DNA 200 secured to the project box? 

Also, have you run case analyzer on your build? The results of that would be quite interesting here.

It has a dab of epoxy in front under the shrinktube and adhesive/epoxied arount back of JST-plug so secured very airy, it has plenty of breathingspace on it's right side

Running case analyzer it just waits for steady temp (currently +20min), should I increase my ambient temp?

I do have some vinyl cutouts on my inside as insulation but I'll doubt that should pose a problem hence it happens without any lid on as well.. switching to kanthal didn't seem to help either, it's been like this past two days only and everything else seems to work as it should.

Case analyzer takes six hours to run, and you need to start with a fairly discharged battery...

Did the problem start when you updated the firmware perhaps? What firmware version are you running?

Running these now

SetupES_2015-07-16.exe / 2015-07-16.sw-update

But have switched back to earler builds & firmware afterwards but doesn't seem to help, will try case analyzer in the morning and give my board a good cleanse as well and see if that helps

Well, the basic issue is that it is running significantly too hot. The question is is it always running hot, or is it just during charging. Case analyzer should be interesting.

My wattage usually at 25-30watts and past two days board getting warm like this so could be an update but I'm not sure.

This part in particular gets warm, if I take a puff while charging sensor kicks in and lowers charging to 0.09, then I have to wait and unplugging my battery seems to help for it to reset.

But will try the case analyzer, should I set USB current to 0 in diagnostics while doing so?

That part also gets warm by just vaping without charging but gets even warmer while charging.

Case analyzer results and differences compared to default settings, I will try and lift/mount my board up a millimeter or so from my casing and see if that helps

How long have you had this one running, out of curiosity? 23F/A seems okay, but running 46 degrees above ambient when idle is way too hot.

It ran a few hours until it stopped, I'm currently lifting my board up a little bit so it doesn't rest flat at surface, can at least try and see

No, I believe the case analyzer results. I mean how long have you been running the DNA 200? Firmware prior to 7/9 could cause chip damage in rare circumstances that we've seen cause excessive heating, but if yours has never been run with firmware that early that would be cause for greater concern.

Can see my exact timestamps in this image between installations, ran first firmware for a few days and upgrading when new builds to avail.
