asciilifeform: kakobrekla: i run at 90-100% load on a typical day
mircea_popescu: put the big iron in the basement. check it out, BingoBoingo vax lives!
asciilifeform: (the thing sounds like an airplane, literally)
mircea_popescu: also this.
asciilifeform: and have the machine far, far away.
asciilifeform: the correct recipe when one has other rooms is to run the displays over fiber
mircea_popescu: well no, you serpentine the tube.
asciilifeform: mircea_popescu: this is louder still
mircea_popescu: it occurs to me, you could just get some of that aluminum foil flexible tubing stuff, plug the case in and have the vented done in the other room.
asciilifeform: (try and take one, run under 100% load on a bench with no flow, on a hot summer day)
asciilifeform: kakobrekla: 'fanless' ps typically relies on there being airflow from cpu+case fans
asciilifeform: kakobrekla: i have fluid bearing fans here, can hear them just fine
mircea_popescu: kakobrekla if i recall the calculations correctly the principal harmonic should be ~285 hz if you 200rpm
mircea_popescu: like in those cartoon "rain cloud 2x2 follows guy around"
mircea_popescu: asciilifeform sooner or later you'll have to face the fact that the turbulence other people get isn't like the turbulence you get.
kakobrekla: at 200 rpm the only thing you can hear is bad bearings
asciilifeform: ever hear of turbulence ?
mircea_popescu: i could faintly hear it, then i had it cleaned for my sins, now i can distinctly hear it.
asciilifeform: silent fan is a lulzy contradiction in terms
mircea_popescu: i can hear the thinkpad.
asciilifeform: pet says i did not go to enough 'concerts'
mircea_popescu: should he ever need to.
mircea_popescu: kakobrekla he has bat hearing, which is why he can feed himself on mosquitoes in the dark.
asciilifeform: kakobrekla: you've just confessed to having poor hearing
asciilifeform: the other thing is that peltiers are laughably inefficient, and you are then stuck trying to cool the hot end
mircea_popescu: yes but there's also thermodynamic equilibrium. you only get liquid phase condensation in some cases on the curve.
asciilifeform: kakobrekla: ANY FAN is audible and therefore too loud.
asciilifeform: mircea_popescu: if you are breathing in the room, there is water.
mircea_popescu: also, they don't have to get below fog point.
mircea_popescu: you need to stop living in a swamp at some point.
asciilifeform: mircea_popescu: mno. condensation. koolance corp. made this, it sucked balls
asciilifeform: afaik this was never ~commercially~ available, there was - briefly - an aluminum thing from zalman
mircea_popescu: asciilifeform no we're not. the OTHER thing you can do is plug one of the ends of those heat inverter units into it. whatever the fuck they call them.
asciilifeform: but we're talking about half a tonne of cu.
asciilifeform: at any rate, the actual 'non-poorfag' thing... exists. it is a copper hedgehog, looks a little like a substation transformer, with MACHINED cavity to mount the mb, cpu, hdd in. 100% convection.
mircea_popescu: technically that's not even on pogo
kakobrekla: http://log.bitcoin-assets.com/?date=19-01-2016#1376546 < get better fans and larger hs - i have done this, cant tell if machine is even running by noise ☝︎☟︎
shinohai: on pogo, the hdd is the only thing that ever seems to get hot.
jurov: oh, these for hdd then
jurov: what about virgin tears?
mircea_popescu: nah, it has to be sealed. it's inert if it can't oxidate.
asciilifeform: srsly, go try it. drown one of your pogos.
gribble: DIELECTRIC CONSTANT AND INDUCED DIPOLE ... - ResearchGate: <https://www.researchgate.net/file.PostFileLoader.html?id=5614bca56225ff66298b458d&assetKey=AS%3A281807657422848%401444199589259>; Chemical Characteristics | The Olive Oil Source: <http://www.oliveoilsource.com/page/chemical-characteristics>; Chemical composition of olive oil - Clackline Valley Olives: (1 more message)
asciilifeform: dielectric constant of $liquid differs from that of air.
asciilifeform: the other thing that you will find, if you do this, is that... the parasitic capacitance nails you.
asciilifeform: mircea_popescu: caulk does not thermoconduct well.
mircea_popescu: asciilifeform just pour some caulk on the upface of the mobo, let it be.
asciilifeform: and in what liquid are we to drown the spinning hdds ?
asciilifeform: something like 400 of them on my mb alone
mircea_popescu: THEN submerge them in pesto.
asciilifeform: go, caulk the 2mm ones, aha.
mircea_popescu: superglue all the things.
mircea_popescu: you caulk them.
asciilifeform: what part of this is unclear.
mircea_popescu: shinohai olive oil is actually not terrible for this role. just, prohibitively expensive.
mircea_popescu: you can for one thing use convection.
asciilifeform: likewise submerged cooling works great for, e.g., mains transformer outdoors, but for 'point source' of heat like cpu, requires circulation pumps, which... noise
asciilifeform: anyway submerging is nontrivial (electrolytic caps soak up your coolant and bloat, then burst) and you can also forget about repairs or upgrade
shinohai: I wonder if I could sell olive-oil cooled computers. Market the oil as being trampled at precise temperatures under the feet of certifiable virgins. Increases the cooling properties.
mircea_popescu: someone else's grandpa tho
mircea_popescu: lmao when we started, computers plugged into the tv. and after 20 years spent spinning in the desert, as we age computers plug into the... tv.
jurov: punkman: i have inherited a working table from grandpa that allows me to have the monitor 1m away
asciilifeform: punkman: seems like you are describing a tv set ?
asciilifeform: just to reduce noise
asciilifeform: (iirc this is in the logz) i DID experiment with water, for years
mircea_popescu: so build one of those submerged rig things.
asciilifeform: fucking hate the noise.
asciilifeform: i'd throw those out also if i could.
mircea_popescu: the last time i had a fanless gpu most of the girls i know today were still virgins omaigerd.
jurov: i know so far. but they are either 28" or $$$ + new gpu in either case
asciilifeform: but i don't have one, it is my understanding that you cannot drive it with a fanless gpu
asciilifeform: there are already several vendors supplying these
asciilifeform: jurov: ever see the '5k' panels ?
jurov: i plan upgrade to Philips BDM4065UC 4K soon anyway
mircea_popescu: hey, some people edit pr0nz for a living. they have to do it on mobile workstation as well as at home and that sixth-inch clitoral hood HASTOLOOKGOOD!!11
asciilifeform: the main problem with the cheap eizos is the not-nearly-enough-pixels thing, imho
asciilifeform: punkman: some people (incl. me) can SEE the dither buzz
mircea_popescu: incidentally, i like the arrangement, ostensibly every window in the backroom opens into a small cell populated by one nude houri ?
punkman: I don't think I can tell 6bit/crappy-PWM monitors apart from the better ones
asciilifeform: the 'poor' eizos still beat the living shit out of everything you see in a konsooomer electronics shop
mircea_popescu: http://www.contravex.com/wp-content/uploads/2016/01/P1180684-1024x768.jpg << check it out, he propped them up on bricks of canadian money. ☟︎
asciilifeform: hey if they work for him...
mircea_popescu: "Why four $800 monitors ? Mostly because I’m not a poorfag" << - >> <asciilifeform> ;;later tell pete_dushenski you ~do~ realize you bought the 'poorfag' non-'colouredge' or 'radiforce' eizos, right ? << lol i'm sure he'll be thrilled to hear. ☟︎
punkman: I'd rather buy 10 LGs for that price
assbot: Logged on 19-01-2016 11:48:08; punkman: those eizo prices http://www.amazon.com/FlexScan-EV2730QFX-Monitor-1920x1920-EV2730QFX-BK/dp/B00R58MLSY
asciilifeform: http://log.bitcoin-assets.com/?date=19-01-2016#1376472 << it's a so-so panel, you're paying for the form factor (iirc the squares are used in airport control) ☝︎
mircea_popescu: last i visited die berliner Huren there were 3 plugs per 2 seat isle
asciilifeform: punkman: it is absolutely SOP. normally the extra bits are only available for the gamma corrector, as the link to the panel is strictly 8 per channel
asciilifeform: in usa, ~some~ LONG-range (e.g., dc to boston) have'em
punkman: I also saw a monitor advertised as 10bit, and then noticed "actually only 8bit" in the small print. not sure if this was in the logs, but quite outrageous.
assbot: Logged on 19-01-2016 12:00:06; mircea_popescu: punkman most trains in civilisandia have power outlets.
asciilifeform: http://log.bitcoin-assets.com/?date=19-01-2016#1376481 << where's that? tokyo ? ☝︎
shinohai: I was sure I would be synced this morning but these last 1k blocks are slooooow.
asciilifeform: punkman: i have a 'modern' one here in this array and it does not 6bit, but ~does~ pwm flicker
asciilifeform: punkman: pretty sure that it's begun to.
mircea_popescu: actually, this would fucking kill - barely functioning deeply retarded webgeek comedy.
punkman: asciilifeform: does eizo do the 6bit thing?
mircea_popescu: punkman or you could go all out on murderous rage, place the box in the luggage space overhead, and dangle a monitor from there by mr bean's sock.
asciilifeform: ;;later tell pete_dushenski you ~do~ realize you bought the 'poorfag' non-'colouredge' or 'radiforce' eizos, right ? the 120dpi 2008-era-panel-but-made-2016-cheapo-6bit-dac ones ?
mircea_popescu: good, save one or two or you might provoke the murderous rage of my mother.
