• Heat cycling is a huge stressor on any material. That’s part of why diesel freight trucks tend to last well past a million miles while it’s newsworthy if a passenger car makes it that long. How many times a week is your Toyota Corolla driving 10+ hours at a time? Most commonly, when you hear of a million mile vehicle, it was making long haul deliveries daily and was maintained at the correct intervals.

      I think there are a lot of other factors in that case.

      The biggest reason why it’s rare to see regular cars get to a million miles is because they don’t get driven as much. At the average of 14k miles per year it would take 71 years for someone to drive 1 million miles. Since it takes so long to get there, many non engine related issues start taking hold like rust and obsoletion.

      What’s the heat stress difference between idle/off and heavy-usage/idle for a PC? If the latter is much bigger, then turning it off may have a negligible impact while still saving some energy. Avoiding heavy-usage may also be a better solution than avoiding turning it off.

        It’s obviously more complicated than can be summarized in a lemmy comment, but that said you’re absolutely correct. That load management is the reason bitcoin mining farms undervolt their cards, so that they can maximize lifetime while minimizing energy usage.
