  1. Lol, trying to claim ownership 15 years later.
  2. So Lew released an update video and it's exactly as expected: he went to an OEM and said he wanted these cases made to these specs for cutouts or thickness or whatever, and they went off and did it. Pitaka decided to get all butthurt and act like they're the only company that has ever made a kevlar case. In unrelated commentary: these cases fucking suck anyways, there's zero point in utilizing kevlar here except to say you're using kevlar, and it's basically just scratch protection for your phone. You drop it in this case you're boned. A thin plastic case would accomplish the exact same thing.
  3. As others have said, there's basically no scenario where it makes sense to use a TEC. It's been tried for the last 10 years, you end up with a massive heat load and a massive power bill to do less cooling than a chiller (phase change) would do to begin with. The only advantage TEC's have is they can rapidly change temperature which is needed for tight process control. Not a CPU application though.
  4. Ehhhh, pretty easy to have a bunch of admins on 24x7.
  5. I have a PMP-600 circulating water with a very good flow rate through 125ft of 5/8" ID tubing, at 24V. This pump is fairly loud though so it's remote located. I suspect a D5 Strong (PMP-450S) at 24V would be able to handle it just fine. I believe there's online calculators that will give you head pressure needed at flow rate through various tubing diameters. You don't need a massively high flowrate here, just like you don't in a watercooling loop because your actual heat load isn't high (ie you don't have a blowtorch going on the water) Also, buy a stacked plate heat exchanger. Never ever try to plumb up your desktop in series with a massive loop.
  6. These are contradicting statements, she's saying the foreign homies offer more value than the local ones. I've worked with several geographies from europe asia and south america, there's certain ones that I much prefer to work with because they do better work with less attitude and others are more problematic for cultural reasons.
  7. I'll bet money it's China being China doing Chinese things. There's 1 factory making cases or a bunch of factories all copying off each other. Shit I can go on Amazon and search anything and find a dozen different "brands" with the same product. And...it's a fucking phone case. There's only so many ways to skin that cat and even if it's identical I doubt you'd be able to legally win, since they're not the OEM's anyways it's some factory in china.
  8. I'm not a pro developer, but I don't think it's so straightforward splitting workloads across cores. With games they can do it in a modular way "1 core handles the graphics, one core handles player movements, 1 core handles sound, etc" but you're not going to get to the point where you have 16 independent tasks needing CPU. I've looked into multithreading some simple data analysis scripts and always end up saying "fuck it" because it's enormously complex to do even with APIs that are meant to make it easier. Maybe I'm just getting old but my feeling in general is we're reaching the limit of human perception for interactive tasks. There's always going to be datacenter / rendering / production tasks where you can use unlimited compute power, but stuff like "how many cores do I need to run Chrome?"....well you're not going to be looking at 300 tabs at once.
  9. Haha, yeah exactly like that. Even down to the streching and creasing of the end tanks, but I also have the bonus of splitting the case apart where the fans can't even be screwed in all the way anymore (can only use like 2 screws instead of 4). It's too bad that I didn't attach a pressure gauge to get an actual number but it's one of those things where you don't know it's going to be that much of an issue...until it is. I would have figured the reservoir splitting apart or blowing another tube off a barb before I would guess the radiator ballooning out. I didn't even notice that's what happened until I heard a fan grinding on something and went to inspect why that was. "wait why is this fan pointing a different direction than this fan?"
  10. Yup, the water peaks at about 72C and because the box is "leaking" heat even though it's insulated, the actual air temperature ends up being about 67-69C. I have 3 temperature probes in the box to monitor it. The base of the skis is porous specifically to hold wax (sintered polyethylene) so leaving them to soak in it for a few hours is the best strategy. 70C is also a lot more gentle on the skis (I think) vs. passing a 130C iron over them but it's probably one of those "it really doesn't matter in the long run" things.
  11. Some people do build these boxes using baseboard heaters and space heaters and lightbulbs and stuff. I didn't because those strategies can create hot spots. Water has a high thermal mass (I open the box and don't instantly lose all my heat) and the temperature of the water is the maximum temperature of anywhere in the box. Skis being made of wood, plastic, metal, epoxy, etc you don't want to thermal shock them if you can avoid it. Plus, I already had radiators and pumps and stuff laying around so it was just a matter of buying an under-sink water heater to round it out.
  12. A literal water heater. My goal here is to generate hot water to run through a radiator to generate hot air. I need 65-70C air temperature in order to melt wax on my skis. The hottest I've ever gotten actual PC water is 45-50C and that's under full CPU+GPU load with just a 240mm radiator in a space constrained case.
  13. I basically inflated, like a balloon, a alphacool XT45 280mm radiator that is rated to about 30PSI (1.5-2bar). It'd be difficult to show in a picture but the case split apart and the bottom is a U shape instead of flat. There is no way you can do this in a normal watercooling loop, I managed to do it by having water that was heated to 75C. Surprisingly all of the gaskets and barbs and shit held together (everything was secured with worm clamps because I knew this pressure was a problem). I was also using braid-reinforced tubing. I'm mildly surprised the plexi reservoir didn't explode first. There was also an EX280 XSPC radiator in the system that took it like a champ and seems undamaged. I'm not going to replace the radiator because it still works and isn't leaking, but I am going to add an extension to the reservoir to allow it to expand and contract freely without overflowing. Sealing the system is bad mmmkay. Aplhacool and Watercool make 5bar - 10bar "industrial" radiators but not in 140mm size, just 120mm variants. I can't actually figure out why there is so much expansion when the water heats up. At first I thought airbubble but I've had it running for ages and don't have any obvious points for air to be trapped (it's possible there's air in the water heater itself since it's designed to have much higher flowrate through it I imagine). I'm not sure if It's simply water expanding when hot, or if it's water not capable of dissolving as much air (gas) when it's hot and the air effectively precipitating out and making its own airbubble.
