Probably Bound to Happen: Increased Power Draw for DLSS 5 Reportedly Claims Its First Victim After a User Finds an RTX 5090 with a Melted Power Ada...

Well, had they done the testing that way, then it blew up later on without the test equipment - that would also be news-worthy. And even if it didn't - still would be very interesting to know, particularly since this issue is very much out there.

But they didn't, did they. Apparently they didn't do any of that valuable meltdown-related data, and they were focused on performance-related metrics. Which is why I asked how measuring meltdown-related data would affect that.

If you are reviewing a card with a 12VHPWR connector and you aren't evaluating volts and amps and balancing external temps and meltdown-related items... you really aren't doing your job. So many of those cards have very publicly went up in smoke that I would consider that data essential to a GPU review... if you have that connector. And interesting, but non-essential, if you don't have that connector.

they should buy a brand new 5090. test dlss5 in various games. establish when the connector blows up. publish that as a video
 
I think bad case airflow is also a factor. If there is no serious air current pushing the heat out, the GPU will slowly get cooked. I can't recall if there's been any reports of a liquid cooled 5090 failing.

A quick gemini query says yes this does happen. VERY rarely... and lets be real. More people dropping a high end card in that are experienced system builders are doing it with VERY solid connections the first time, NOT doing multiple re-seats 'because it might be having problems.' and generally have solid cooling.
 
Usually, for electrical fires - air flow often makes the problem worse by spreading the spark/heat out faster

Electrical is usually a high impedance/resistance connection with just too many amps going through it (P = R * I^2), and it's a very small, very hot point source - and that spreads to nearby material which can ignite or melt. Air flow ~could~ help but most of the time it's buried inside a connector or a junction box or something, and blowing air across it just makes the flame spread faster when the material ignition eventually occurs.
