mircea_popescu: how hot was the radiator getting ?
asciilifeform: the mosfets did not cook themselves - internal thermal trip. you get a shutdown.
asciilifeform: water line ran through two cpus, disk jacket, gpu. there was still some air circulation from power supply (conventional air cooling.) but sans case fan, machine would croak reliably.
mircea_popescu: well, was this the toyota radiator thing in the image ?
mircea_popescu: as long as you keep most of the board cool, mostfets can't make enough heat to cook themselves.
asciilifeform: the box in question would croak after 48 hrs. or so if the case was not ventilated.
mircea_popescu: i'm telling you, they'll be fine. you're thinking in terms of air movement removing heat, but even in a sealed case,
artifexd: Unless it's an Asus board. Then the designers thought it would look cool.
asciilifeform: heuristic: if mosfet has even a small 'hedgehog', the board designer thought pcb trace cooling to be insufficient.
mircea_popescu: if you cool the bridges it'll cool through there.
mircea_popescu: if you keep the board cool they'll be fine
mircea_popescu: <asciilifeform> pc mobo is encrusted with items like mosfets that presume circulation of air << not really. mostly actually cool through the metal of the pcb
artifexd: It's the plumbing replacement for copper. Flexible tubing.
artifexd: Is that pex?
assbot: imgur: the simple image sharer
artifexd: My system is all contained in the case.
artifexd: Ugly as hell, but it seemed to work for him.
artifexd: My ears aren't near as sensitive as yours so I'm good with a few slow moving fans on the radiator.
artifexd: Ah. Yeah. Blocks for motherboards are available. They cover the north bridge/south bridge and the power caps.
asciilifeform: my sole objective was to get a silent machine
asciilifeform: pc mobo is encrusted with items like mosfets that presume circulation of air
artifexd: The heat has to go somewhere
asciilifeform: artifexd: any that guarantee operation with 100% hermetically sealed case? (no case fans)
artifexd: Waterblocks are available for just about everything now. It can take some looking. They aren't cheap. But they work well.
asciilifeform was disappointed with water cooled machine even while it worked, on account of it still needing a few fans to operate: various parts for which no water block was available (chipset, mosfets, and power supply of that period)
artifexd: I don't think I would use copper tubes. My configuration changes too often.
asciilifeform: artifexd: then the answer is clear. 'teflon' tape on the threads, connectors glued (or welded, if copper hose) to the tube.
artifexd: Most decent water blocks don't come with connectors at all. Just threaded holes.
mircea_popescu: artifexd imo the interior/exterior distinction is spurious. both work the same way really.
asciilifeform: artifexd: neat. these weren't available a decade ago.
artifexd: That's how you connect the barbs. Screw 'em in.
artifexd: Every one I has is threaded
mircea_popescu: asciilifeform but if they're metal... you can thread it
asciilifeform: mircea_popescu: part of the problem is the abysmal, 'consumer' quality of the available thermoblocks (pumbed heat sinks that fit particular cpu, gpu, etc) - not one, afaik, to this day, comes with even threaded connectors
artifexd: The work in conduction with the barb. The barb provides interior pressure against the tube. The zip tie provides exterior pressure.
mircea_popescu: (this neatly dovetails in stan's "deform barbs" problem above : if you're building an army you don't want a 2nd cavalry, to argue with your 1st. you want an infantry too)
mircea_popescu: but they work on the same principle as the barb does.
artifexd: Zip ties are cheap, clean, provide uniform pressure, and are easy to remove with no mess.
mircea_popescu: artifexd why do you prefer zip ties over say caulk ?
artifexd: I need to find a single video card that can drive all my monitors. Then I can get rid of the water cooling.
asciilifeform: artifexd: there's probably a golden mean here. a real 'saint' with a dynamometer wrench probably could've tightened the clamps exactly enough.
artifexd: Ever had problems with the compression connectors?
asciilifeform: artifexd: mine had hose clamps on all joints. theory - clamping deforms the barb, you leak anyway.
artifexd: I prefer zip ties
mircea_popescu: artifexd you know you could just glue it on the outside.
artifexd: asciilifeform: That's exactly what happened. One of the connections decided to call it quits. It's what I get for using barbs and not securing it.
asciilifeform: the photos i saw were of immersive oil cooling (think transformer booth)
asciilifeform: mircea_popescu: it's the friction joints (hose to barb) that end up slowly leaking.
asciilifeform: mircea_popescu: the 'correct' way to do it is to have an all-copper loop, soldered joints - like refrigerator. but, for some reason, no one does this.
mircea_popescu: asciilifeform you should prolly look into it again. you thinkl moore law's a big deal, give a look at plastics.
mircea_popescu: time to sue her ? :D
asciilifeform tired of drowned hardware many years ago, won't touch water cooling now
artifexd: Also, oddly, in my wife's office. Not in mine though.
artifexd: Yep. We have them in both bathrooms and all over the kitchen.
artifexd: asciilifeform: Will a GFCI fire fast enough to save a power supply in the face of an internal short?
asciilifeform: artifexd: common widget, usually installed inside kitchen mains sockets, which senses even small difference between current flowing in through 'hot' and leaving through 'neutral' wire (e.g. through your arse)
mircea_popescu: so how do i leave a comment or anything to this tom guy ?
mircea_popescu: fluffypony lol the rat trap is falling apart is it ?
mircea_popescu: jurov: is this KeyError: " " ? << no that's some db issue

mod6: lol @ the system Z pics. thanks kako, a bit nostalgic now.
punkman: kyuupichan: he could still spam the blockchain in 1000 other ways
kyuupichan: At some stage he's gonna piss off enough people that they agree to ignore his block and continue to build on the prior one. That'd hurt.
fluffypony: "Not only does the Bitcoin Foundation suddenly make you seem reputable they will help you with this. They’ll post blogs about you joining, even sending out the “brass” to shill blogs such as CoinDesk to push you joining to others and making you seem further legit."
punkman: http://bitcoinsberlin.com/ any of these guys in the wot?
xmj: I have .net and don't use it but for email ... why do people not see such things :(
xmj: i got a mail to my company address, asking if i'd wanted to buy chaot.net
fluffypony: speaking of new TLDs
jurov: things to look into someday...
jurov: but then it stopped working at all
xmj: jurov: looks like a variable that should be set isn't
fluffypony: I struggled to get server working on Ubuntu 12.04, needed to install python-leveldb from backports and all sorts
jurov: is this KeyError: " " ?
assbot: Server crash after restart while reorganizes the blockchain Issue #61 spesmilo/electrum-server GitHub
fluffypony: https://github.com/spesmilo/electrum-server/issues/61 - that happens all the time, but erasmospunk's fix has been ignored
fluffypony: jurov: it's not that bad, it's just not very well maintained
jurov: server is quite turd-ish if you wanna run own
mircea_popescu: * mod6 is merging code & listening to NIN << hurt ?
benkay: general idea is that 0.6 is okay.
benkay: plus cpp turd
benkay: i was recently made aware of a thing by the name of 'armoryd'
xmj: someone care to recommend a bitcoin client, gtk preferred?
benkay is reviewing tickets and listening to mingus
mod6 is merging code & listening to NIN
benkay: aight i'm smokin some pots and listening to ah um
benkay: <mircea_popescu> btw, if anyone's got 12 yos, get them "i sell the dead" // noted

mircea_popescu: punkman shot the guy an email anyway.
mircea_popescu: fix the fucking plumbing. once the fed stops leaking, the mold goes away. big whoop
punkman: "The best bet is to try to convince people not to invest all their money in undiversified opaque get-rich-quick schemes and, come, on, this is America."
punkman: "You'll never deter Ponzi schemers; the psychology of Ponzi'ing -- either "I am an invincible genius" or "I've lost my investors money and have no choice but to Ponzi my way back into the black" -- sort of precludes deterrence."
mircea_popescu: and nobody to date ran anything for 25 years
punkman: "I like Institutional Investor's boldness in picking "five hedge fund managers who are likely to deliver market-beating returns over the next 25 years." Who even manages a hedge fund for 25 years? If you deliver market-beating returns for 22 years, come on, retire, you are already fantastically rich"

punkman: I wonder if this was always in their ToS: "Project Creators are required to fulfill all rewards of their successful fundraising campaigns or refund any Backer whose reward they do not or cannot fulfill."
mircea_popescu: that 5 to 20 year latency of teh legal system
punkman: it worked long enough for them to get big
