As recent as last year their coolants were on "do not buy" lists because of clogging blocks. Few years ago they were talking shit about Mayhem coolant being to blame for their plating failures (again) and then they got dunked on when Mick @ Mayhem was like "oh yeah BTW you guys were rebranding our coolant anyways sooooooo yeah". Years before that their "warranty void if sticker removed" bullshit. And overall their stuff is pretty much always the most expensive option and when you put it up against Alphacool or Watercool it isn't even close in terms of hydraulic design quality or finishing. Their business for the last 10+ years has been "max $, minimum quality, and accept no responsibility for any failures in field". So my recommendation to everyone whose like "oh should I buy EK?" nope, go on aliexpress and buy Bykski and it's the same thing at 1/5th the cost. Or pay slightly less and buy Watercool or Alphacool stuff that is bomb proof.

I'd be fine with EK disappearing. Quality on par with China and price on par with Europe. But every kid buys them because they don't know any better than sponsored youtubers telling them that's what they use *cough jayztwocents*. And I'll never forgive or forget them blaming literally everything but their own shitty nickel plating. Hell I have a picture somewhere of their "gold" plating peeling off.

FTLOG if you're doing whole room watercooling again: learn from the last time and use water to water heat exchangers. Don't just plumb everything directly into the cooling loop, cause then you're fucked with gunk and microbes and shit in your waterblocks...again. Here's my credentials: (the air to water radiator is being used to cool the room itself...not to cool the water)

Lithium hasn't worked its way down yet to the consumer space but it really is way better overall for UPS's since it offers 100% depth-of-discharge and the batteries will last 10 years instead of 2. I had to build mine myself to stay under $1000 (it's basically the same thing you'd put in an RV. Lithium battery, DC-DC charger, 12V power supply, inverter). But it's online (aka "double conversion" because it's doing ac - dc - dc - ac) so it wouldn't be practical outside a utility closet unless you don't care about 24/7 fan noise. And it's more expensive to run because it draws 30% more power than it supplies with the efficiency losses. It'd be more expensive to have automatic transfer switch to run off utility power and switch over to battery fast enough to not interrupt electronics. So if you want to go the standard UPS route I'd look at the runtime charts for APC / TrippLite / CyberPower and then decide how much time you need and buy from there. Sustaining 800W for more than 20 minutes gets expensive with the readily available stuff (I personally targetted 2 hours to match the longest power outage every experienced here). If you want to rummage around and save money you can find rackmount stuff or retired UPS's on ebay that just need new batteries put in them. There's loads of stores that will sell replacement generic batteries. It's easier to say "I just need 5 minutes to save stuff and shut down" and then play on your phone while you wait for grid power to come back.

Kinda a useless question without knowing your budget. You can go from $200 - $2000. Clean power only exists with online UPS's which are going to be closer to the $2000 range. And I wouldn't really target that unless you know for a fact you've got power integrity issues. You have to assess. Are you *really* drawing 500-800W regularly or are you estimating? Do you *need* all of your desk to have power during an outage when you're probably going to lose internet too if your modem and router aren't on a UPS? How many minutes are you expecting power to be out? Are you prepared to spend $100 every 2 years to replace lead acid batteries if you don't step up to the $$$$ lithium UPS's?

Stacked tiles are going to be the same problem though. It's going to be even worse on the datacenter side where the cores are in middle layers of the stack.

D-Link did the same shit...just one day decided they didn't want to pay for servers anymore for their wifi switches and water sensors and shit. Annnnd never buying a D-Link product again.

They do: against the Play store. You can't go to McD's and say "hey your Big Mac is great but Burger King over here wants to sell Whopper's out of your lobby too". There's fundamentally no difference between this vs. the app store arguments. Apple didn't grow iOS and then one day kick out every other app store. You knew what you bought into.

Apple users don't avoid switching Android because they're being blocked from doing it. They don't because they don't want to. The entire strength of the Apple ecosystem comes from it being centrally managed by Apple. iMessage is good because it's run by Apple. Apple Pay is good because it's run by Apple. The app store is good.....because it's run by Apple. You open this shit up and you end up with the Android shitshow where nothing works with anything else and a 5 year old can hack it because there's more gaping holes than a BDSM porn set. If the DOJ is bored why don't they sue Nvidia...who has an actual monopoly on everything GPU compute right now. Oh yeah because it's harder to explain that in a press release when it's an election year vs. "iPhone bad"

Pure alcohol evaporates hard. So what's your plan for making a sealed enclosure that still has IO ports? But in general if no one has done something it's almost always for a reason. Probably no one wants to handle gallons of a volatile solvent when there's other stuff out there that is much safer.

He still hasn't learned from Whole Room Watercooling: glycol isn't antimicrobial by itself. It relies on whatever you're cooling being 100C to be sterile so it's going to be screwed up shortly. You have a 3d printer and a CNC and that's your manifold situation with silicone holding it together? I'd have spaced everything out with a 1U gap and put drip trays with drain ports between each machine. And put a contact sensor on the drain so if water ends up in there you get an alarm.

A couple of degrees spread is basically nothing:

All thermal pastes are near-as-makes-no-difference the same performance. Sub zero you might need a different paste that won't freeze, direct die you can run liquid metal if you want to insulate the area around the die. Other than that, there's no difference between $1 generic and $10 Kryonaut.

Didn't forget about ya, it just took a month to get the printed parts delivered. Looks like the dude use .1mm layer height cause it's finer than I've seen before. Anyhoo HOLY SHIT does the air guide work a treat. The videos make it much more obvious than the screenshots here but without the guide the stream breaks up within 18". With it, it's solid out to 3' easy. (the smoke is burning mineral oil, meant for this type of purpose) Video without the air guide: Video with the air guide: Turns out I also stumbled on the correct size of the funnel "vents" to not retrict the fan with the engine running. I measure about 11mph peak speed on the fan with no restriction, it drops to about 9.7mph with the engine off, and goes back to about 11mph again with the engine on indicating it's full flow. I don't have a great means of visually showing it, but I can feel the warmth of the exhaust on my hand much further behind the car so it's *throwing* it like I wanted.

This was my question. "why is he trying to make 1U systems in the first place?" Fuck the rackmount, get some shelves and put a stack of narrow ATX cases on it. Oh look .... it's actually what "pros" do too: I see this a lot in my day job. They're so eager to dive into the "solution space" of cramming shit into a 1U case that they need an adult there to say "hey why are you having this problem in the first place? " He's not a datacenter where rackspace and floor space is revenue.

Nothing about that sentence implies the lenses are permanently installed or can't be removed for resale. Kinda jumping to conclusions eh? I'm also doubtful that Zeiss is pre-making and "stocking" every prescription combination. It's literally tens of thousands of possibilities when you factor in astigmatism and the axis angles. They would do what every other eyeglass / lens lab does which is made-to-order. It's probably the Bloomberg guy misunderstanding the supply chain and *really* Apple just doesn't want to deal with separate lens orders and packaging and shit when they can deliver a prescription package in one shot.

Yup. This isn't even a step in the right direction it's a waste of time. They won't even go offshore they'll just switch their AWS region for storage to Oregon or Texas and "oh look we don't have any data in CA anymore" Prop 65...for data.

This was my $20 take on the headrest mount, since it only needs a saw and a quick welder zap (shaft collar is the keyword). If you've got a CNC you should have a welder...doesn't take much effort to learn either. This is also a repurposed VESA mount so it takes regular monitors up to 24".

TLDW: Kinda looks the same size to me?

Sigh....it's like every year or so someone thinks they've discovered peltiers. The end of this story is just use a water chiller if you want slightly cooler water. It's not going to improve your overclocks by enough to make it worth the electricity cost.

This is the one I'm currently using and seems to work fine plugged into a USB 3 hub: https://www.amazon.com/gp/product/B0B3JTLQ9S/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 Basically every component is $160. USB, 3x monitors, $640 for the whole harness to run my desktop in the utility closet.

The problem in the really small form factors is heat management more than anything. I use a thermaltake core g3 with a 3090 + 9900 (think it's discontinued now) as my PDXLan rig because it fits in a suitcase and I Can put a 27" monitor on top of it neatly, and even being larger than carryon size (it probably could fit in a carryon if I significantly reduced the padding around it) it's still really hard to extract heat off it. And that's with the whole thing watercooled where I just need to slam the beefiest fans possible on the front of the case. Have you considered something like the Core eGPU or similar TB3 enclosure with a laptop?

Ya it was a weird dance combo of having a powered hub but not powering the receiver itself. And getting ground loop noise if I powered the receiver and the hub but the hub wouldn't work if it wasn't powered. And then I came to the conclusion there's probably only 1 chinese silicon chip that all these "brands" put in a plastic box. Similar deal with the USB hub chips where I had to go through like 5 of them before I found one that worked and figuring that even within the motherboard by itself there's like 3 layers of hubs baked in as it goes through the chipset through something else where it splits front panel and rear panel, through something else and then it ends up on the back of the motherboard.

The video is talking about USB over ethernet, not USB over IP which is incredibly niche to where I can't think of any scenario a normal user would want that. VNC-like software probably dominates most every place it could be contemplated.

Fiber displayport. You're going to pay at least $150 per screen though and some of the fiber tranceivers are shittier than the others. If you only have one screen and don't need gsync it's cheaper to run fiber HDMI. Audio you either do with optical SPDIF or a USB DAC to a USB hub, running over USB fiber. KVMs are more of a thing if you need to access a lab system from your desk in an office building where the KVM is basically a mini computer. They know you're probably using it to make money too so that's why they're expensive AF.
