            No redundancy? No high availability? No clustering? What are you even doing man? One server? Those are rookie numbers. You gotta bump those numbers up.

            /s, obviously. You do you, and whatever works for your needs/budget.

                Are you able to easily attach spinning rust hard drives to those? If so, how? I think those things use more than 5W on their own. Biggest question I have before planning a horizontal raspi setup. Currently I use old x64 PC boxes for self hosting.

                  I’ve used a 2.5" hdd on a rPi before using a usb-to-sata adapter (powered from rPi’s USB port). I’ve used a 3.5" hdd using an hdd enclosure that’s externally powered.

    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 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.

      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.

    Fridges actually do rest. They cycle on and off as needed to maintain their desired temperature and on average only spend about 30% to 40% of their time “on”.

      That is assuming they are in good working order with no broken seals anywhere. They will run continuously if they never manage to get near the target temp. Though in that case, your food is probably also not getting refrigerated and you hopefully notice.

      I only found this out the other night because my fridge went dead silent for a long time. I thought it was borked, so I was peering deep into the freezer when I saw The Gates of Hell through the grate.

      (Okay, so full disclosure, I had smoked some pot, but it totally looked like when Dana opened the fridge to Zuul before she was The Gatekeeper.) 😱😱😱

      Anyways, turns out it was in defrost mode (which happens twice a day), and that involves some elements going orange or something. I know that’s vague-- I looked it up, but as I mentioned, I was high, so I only kinda remember, lol.

      Edit:

      The refrigerator activates a heating element located near the evaporator coil. This element warms the coils, causing any ice buildup to melt.

      Actually modern fridges are usually less efficient. But that’s because they use refrigerants that are literally thousands of times less harmful to the environment.

      Old appliances frequently used R-12 which is an damn nice refrigerant except it depleted ozone and has a GWP (global warming potential) of 10,900. That means 1lb of R12 released into the air causes the same amount of global warming as releasing 10,900 lbs of CO2.

      Newer appliances use refrigerants like R134a which still works pretty well, doesn’t deplete ozone, and only has a GWP of 1,430.

      The newest appliances are more frequently using R-600a which is hard on compressors because it has a high head pressure and it doesn’t cool quite as well. But it also doesn’t deplete ozone and it has a GWP of just 3. The bigest downside of that one is that it’s very flamable (it’s isobutane) so the legal limit on how much residential appliances can us is very low.

        I’ve read somewhere it is because conpressor nozzke has to be made thinner/fragiler for the better efficiency. Other comments say it’s because old refrigerants were better but more “dangerous”. Maybe both.

      Old appliances broke, but they were made to be easy to fix so our grandparents could just swap out the broken parts. I helped my dad replace the compressor on an older fridge as a kid and the heating elements on my grandma’s toaster. I remember my dad taking me to some locally owned mom and pop hardware store where we could buy replacement parts for old appliances off the shelf. My parents still have the toaster, but that store closed down and new stuff isn’t made to be fixable anymore (most likely due to planned obsolescence thanks to late-stage-capitalism).

      On a tangent, when you think about it, throwing an entire toaster away because one heating coil burned out or throwing awag an entire fridge just because the compressor gave out is not rational. But if you tell people we should have the freedom to buy repairable appliances then they look at you like you are crazy. To me, it is the other way around. Sustainability isn’t political or a luxury, it is an inevitabe, unstoppable force of equilibrium.

        When it comes to refrigeration in particular newer appliances tend to break more frequently because they are using more environmentally friendly refrigerants. Old CFCs cooled really well with minimal work from the compressor. Newer fridges and freezers are more frequently using isobutane (R600a) because it doesn’t deplete ozone and it’s GWP (global warming potential) is 3 where the GWP of even non ozone depleting HFCs can frequently be in the thousands. The problem is isobutane requires higher head pressures to work properly and doesn’t cool as well as older refrigerants so the compressors have to work much harder to get the same result.

        Also when it comes to household fridges and freezers, they really aren’t worth it to fix anymore. You need an EPA 608 cert to even touch refrigerants (in the US anyways). Plus you need a two stage vacuum pump and a recovery machine (amongst other things) both of which can easily cost as much as a new fridge. Then you need to actually have the skillset to remove the broken component and braze a new one in because everything uses brazed connections now to minimize leaks. Then you need to have the know how to properly recharge the system with refrigerant which when you’re working with a critical charge of maybe 2oz of refrigerant is an absoulte pain. All in all, maybe if you are already an HVAC tech and had the tools and materials on hand you might barely break even fixing your own fridge or freezer.

        When it comes to consumer refrigeration they can’t be user repairable due to having to work with refrigerants and economies of scale mean they just generally aren’t worth a trained techs time to fix.

    We’ve had a GE fridge that’s probably older than about 10 years. But you know, it’s complicated enough that it feels like it’s made to fail at some point.

    Well, stuff stopped cooling but all the lights were on and everything else worked. It was really weird. We were thinking it might be a dead compressor or something. Crap, do we need a new fridge?

    Nope! What basically amounts to a glorified computer fan with a fancier proprietary plug does all the work of distributing that cold air through the rest of the unit.

    The proprietary plug is totally so they can sell it for $45, of course. Lol anyway, works like new!

    Also get a dust mask and vacuum + blow out the back of your refrigerators, people. They get grooooss!!!

      Ya. That black server fan in the frig is very common for the model of frig…also the little white resistance sensor on the coil tends to fall off of the tube sometimes causing it to defrost poorly. I like to swap them out when I’m doing the fan as a prophylactic.

      The reason they use that fan is because it’s super quiet and voltage can be regulated to it for different spin speeds which I turn is supposed to save energy.

      The issue with the fan in and of itself is that it’s inherently an aftermarket fan produced by an aftermarket manufacturer for GE. It’s just junk.
