    Thermal cycling is one of the biggest stressors electrical components can be subjected to. Leaving your processor on and at a consistent load massively improves the lifetime of the chip. So take THAT, mom!

      I run prime95 24/7 on my AMD FX-9590 to keep it at a nice stable temp. Plus it means I also don’t need to heat my house in the winter. Gotta love a tdp of 220W.

      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.
