The caps might have blown up, but it's unlikely they were the cause of the fault. Unless they're cheap knock-offs, those SP-Caps are all rated to a working voltage of at least 105C (some are 125C) and they'll survive higher than that. What they don't like is an overvoltage situation. Those specific ones are rated to 6.3V, but if something happened where the full 12V (or most if it) was across that chip and cap, it would look very similar to that.

Assuming it was not done on purpose and it was done on a standard freq of 350 this could mean the s-5 has the same problems Asic Miner prismas had. Runaway thermals. Time will tell if it is the case or if this is a rare case. So far 1 person has had the problem. Thousands have been sold. So 1/2000 popped a pair of caps. Pretty safe we have seen more then 1 burned sp20.

To me it seems strange, that a board failure is SO rare on the 10,000s of units out there, yet TWO happen on the same unit simultaneously. Statistically that just isn't possible, there must be something environmental influencing the situation - whether its the fan was changed out, someone tried pushing an overclock too far etc etc. The warped plastic panels also don't appear to make sense, there is no reason why the air on those panels would get anywhere near the 105C or so to melt them.

My personal opinion is we're not getting the full story, but its not up to me to decide. PM BitmainWarranty to arrange an RMA. Be sure to link to your post describing the issues, what type and how many miners you wish to have repaired/replaced and your bitmaintech.com order number.

will do - wasn't trying to start something, was just curious about the 80C safeguard

Yeah that's okay. If the chips [sensor] were at 80C I'd still be surprised if there was enough radiating heat to warp the [assumed] PP/PC sheets so its a weird one. The 80C safeguard does work though, its been tested.
