I don't see how that could have burned up those particular connections / components. Especially the fan feed wires! How the heck did they manage to overheat? Them being burned up indicates to me that the fan is the possible culprit!
These pods and those components are supposed to be able to handle a good amount of current and heat while mining in dual mode. 60W at least!
More investigation needs to occur before the actual 'reason why' can be determined.
well if modded they use like 15/20 watt, how much watt could they draw on dual mode? maybe that's the problem?
yes, obviously, they do draw more in dual or sha only mode.
The thing is, if there are lose or poor solder joint connections, this will cause a rise in current draw hence, heat and catastrophic destruction will ensue! Just like it did there...
For the fan wires to have melted and distorted the way they did, the heat from the entire pod would have to be like 350+ degrees! Highly doubtful that happened.
For the fan wires to have melted the way they did, the heat would have to be generated by the 'elements' / wires - themselves.
That's what I see. The rest of the components were burned up via a short and that, perhaps is what caused the solder connections to melt and open.
Or, I suppose it could have also all happened in a flash! That 12V connection can have as much as 30 Amps on it at any time 'surge amps' if the psu is a 30A unit. Even 10A can do it. Heck, 5A could do it too I recon but it would take longer.
It's also possible that the psu took a powder and caused the damage as well. A high current spike, a high voltage spike, of some origin could cause it as well. Something like a lightening strike could certainly cause it as well.
