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!
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.
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.
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.
I’m over here just over 30k miles after 6 years
I had to scroll way too far to find this. Especially considering that I have a desktop with full disk encryption, I don't worry about it. If anyone ever did break into my house and take my computer, they would have to unplug it first; at that point, the disk would encrypt, and they'd have some really nice hardware which sucks for me, but that's all they'd get.
The disk is always encrypted. When data is accessed, it is stored decrypted in RAM. The drive doesn't decrypt when unlocking it and doesn't encrypt when turning it off.
I feel that. All the information stored on my PC isnt worth a fraction of what my graphics graphics card cost...
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.
