Pentium chips and mining chips. Apples and Oranges perhaps? But for your information at the moment I only operate Antminer S5 products which I understand operate from 0C to +/-35C.
That means it should work fine at 100 degrees F. Like other semiconductors, it must not suffer a hardware failure until temperatures are hundreds of degrees higher. 35 degrees only says software crashes may occur when the room exceeds 100 degrees F. Which means semiconductors that are even happy and normally at 100 degrees C do not fail. At those temperatures and due to insufficient design, some semiconductors can cause software crashes. That does not damage hardware. Cool semiconductors and it executes same software just fine - for Intel, AMD, FPGA, GPU, or ASIC designs.
Hardware damage never occurs at these near zero temperatures. These normal operating temperatures include a room at 100 degrees F, semiconductors at 100 degrees C, and no hardware damage.
Hardware damage does not daisy chain into other parts - except when damage is flame. Flame must never happen in any electronics. Flame only occurs when a design is overtly defective due to technical ignorance or cost controls. Flame means a complete design failure in that product and probably others from the same manufacturer. Flames must never happen no matter what environmental act caused that failure - even a direct lightning strike.
No burn indication is in the picture. Did it spit flames or just smoke - a major difference that many overlook? Smoke is acceptable. Flame means all products from that manufacturer may require a major recall.
Eight signal wire connections exist - six power connections are not visible. Failure of one capacitor is typically a manufacturing defect - either due to a defective part or due to a cost controller (ie business school graduate) doing the design. Cost controls actually increase costs as well as reduce product quality.
Turn off hottest hardware without any fan. It never gets hotter. Hottest spot - where failures happen - only get cooler when power is removed and no fans spin. Nothing gets hotter when power is cut. No special care is necessary for power offs. A chip at 100 degrees C does not increase to over 300 degrees C when power is off - so no hardware can be damaged. All hardware has no damage even if the power off is due to the nearby nuclear power plant shutting down. However unexpected power loss can harm unsaved data.
Most all failures are directly traceable to manufacturing defects. If hardware fails (when new) at maximum temperature doing maximum work, then the hardware is 100% defective (even though it works fine at lower temperatures). That is true for all hardware - AMD and Intel, GPUs, and ASICs. A highest temperature failure today means to expect future failures (months or years later) at lower temperatures. How to keep defective hardware working? Lower temperature of the incoming air flow.
Most destructive failures are due to manufacturing defects - not due to bad ground, dirty power, or bad PSU. Those three suspects only cause software crashes - do not damage ASICs. Fix those defects and all semiconductors and capacitors must be just fine.
In that one failure, informative would be a picture of the actual destroyed C456 capacitor and the adjoining (electrically connected) parts.
