[Charlie Austin] "Take this with a grain of salt, but, regarding Deadpool MP meltdowns, some of the team believe it's a computer issue, but some are just as convinced that it was caused by issues with the Beta versions of PP they were running at the time. FWIW"

[Oliver Peters] "It may be a combination of both."

[Darren Roark] "I'm guessing though that the beta version of PP was the culprit since the safety measures in the machines seemed to fail. Transcoding Red footage in FCP X varies in speed transcoding the same shot depending on how hot the machine already is. If they didn't account for that anything's possible."

If GPUs are "melting down," it is a hardware problem, period. Electronics generate resistive heat when they are used, and the harder you push them, the hotter they get. If a design does not accommodate this fact, it is flawed. The system should stay in a safe operation range and be prevented from entering an unsafe state by design.

We've had thermal throttling in hardware for decades. The hardware itself enforces that performance slow-down to keep itself safely cool, and it should shut down completely before it ever reaches the point where the heat would be damaging.

Maybe if Apple system designs put performance on equal footing with case size and aesthetics, this wouldn't be an issue?

A couple of related quotes from

A unified thermal core. The new Mac Pro packs an unprecedented amount of power in an unthinkable amount of space. A big reason we were able to do that is the ingenious unified thermal core. Rather than using multiple heat sinks and fans to cool the processor and graphics cards, we built everything around a single piece of extruded aluminum designed to maximize airflow as well as thermal capacity. It works by conducting heat away from the CPU and GPUs and distributing that heat uniformly across the core. That way, if one processor isn’t working as hard as the others, the extra thermal capacity can be shared efficiently among them. No computer has been built this way before. And yet it makes so much sense, it’s now hard to imagine building one any other way.

A single breakthrough fan. An incredible amount of innovation went into designing a fan system capable of cooling such a high-performance device. Instead of adding extra fans, we engineered a single, larger fan that pulls air upward through a bottom intake. As air passes vertically through the center of the device, it absorbs heat and carries it out the top. It’s simple and elegant — and also astonishingly quiet. To achieve that, we had to consider every detail: the number of blades, the size of the blades, the spacing of the blades, and even the shape of the blades. By minimizing air resistance throughout the system, we were able to design a fan with backward-curved impeller blades that runs at fewer revolutions per minute, draws air more efficiently as it spins, and creates considerably less noise.
