Thread: Oil cooled PC

I have no idea what you just said or what you are trying to do but it sounds cool

THIS WILL BE AN OIL COOLED PC , ie , THE MOTHERBOARD WILL BE SUBMERGED IN OIL FOR COOLING

No actually one side will be real hot , pump all the the heat into 1 tank , the the radiator will work better if its at 120c ,

a radiator in a single tank system is trying to cool 40c in a room temp of 30c , it dosnt happen '

the difference with this build is 2 tanks ,, the second tank can get real hot , so the heat exchange works too room temp ( yer pelteirs will add 2 x as much heat , but its needed ), at 120c the radiator will cool 4x better , than at 40c , so the double wattage from the huge stack of peltiers is 1/2 coz the the temp is 4 fold .
??? pump all the heat into a tank and the radiator will cool it , the higher the temp , the better the radiator works ,

the chip will be an "775 socket intel 4core duo extreme " ive bet my house mate i can get my old pc to run better than the new one ( i7) , if i can get -10c chip surface temp , it will s h i t it in

peltiers can only cool 68c below there hot side heat , then run away heating happens , ill double stack them so its at 120c , yes , 13 x 150 watts is a huge amount of heat to get rid of 400 watts from a chip
double stacking peltiers , what ever the temp of the hot tank is , i can run 120c under that to the hot side of the chips peltier , THEN THE CHIPS SURFACE MAX IS 68C BELOW THAT , if i can get the mother board tank to 10c , the main chip will run at -50c , i can over clock the crap out of it , with a hot tank at 120c

so the chip will revive cold oil ( 120c below the hot tank temp ,) , and have its own peltier between the ( water bock housing ) and the surface of the chip , yes , use water cooling blocks , at 10c mother board tank temps " with peltier cooling

hehe, you nerd! Make sure to update us with the results

yer ill show you the fried bits if i fail even the blown out capacitor's / pvc hoses 18 months from soaking in oil , started with the sealing of the mother board today , im thinking it would be easyer to flood the mother board in epoxy at 1mm deep to oil proof the capacitors , the main chip will be a challenge to oil prof just glue it in i say , ?? ill think about it before i epoxy the chip in

cut out the aluminium plate for the mother board today , got her bolted down on draw runners and working on the power supply mount / pump holding plate


why the hell not , ill post the dxf's of the parts i cut by CNC

this zip file is of the ATX motherboard bolt down screw pattern , and will fit standard draw runners( 450mm cut down ) its in a EPS format

did a bit more on it today

dont you hate it when you turn up for work to find out its a public holiday ???? "Darwin CUP " day ??? pitty the southern news didnt say anything about it at all ???

so drew up some more parts , and milled them in 3mm aluminium sheet , the back plate to hold the 2 power supply's , and the front plate

now i have to sort out the wiring , got a stripped down "cheep crap"1200watt ATX to power all the PC goodies ,
and a monster ( blown up ) top brand 1200watt ATX for the peltiers , this sucker has 6x good and working 38Amp 12volt rails,
a friggin monster ( it cost a heap as well ) , a lightning strike killed it 3 years ago , the 3.5volts and 5 volts are fried , so its been relegated to the junk pile , but 6x 38 amp 12 volt rails , wow , ill run it at 1/2 power , i had to change the pug over to a 15amp pc plug with both of these suckers running , the number of peltiars just went up

6 rails at 38 amps ????? run each rail at 16 amps ( 4 peliters per rail ) 24 , well + the chips , 25 of the suckers ( ill order more ) , and double the insulation to 50mm thick , and add another radiator

also ordered 4 USB plugs , and 6 SATA extension plugs to bring then out of the oil too the rear plate , with having them to measure i just cut out blank slots in the back where i can machine up a plate to fit them later

Woohoo!

And as a bonus, even if it doesn't work you'll still have the best beer cooler outside of the antarctic.

yer chill your beer in one side , and cook ya chips in the other

ive been trying to find a decent " dielectric oil" ,

i cant even find a shop or referral to a shop to purchase this stuff in Darwin , once again " bye local " is a waste of time , so straight of a yanky distributor it looks like , and get "right royally rodgered" by the US postal service

veg oil , cooking oil will work , but has a high freeze point ( turns to jelly below freezing ) and will stink
mineral oil is better , costs more and destroys PVC / rubber over time

some others vent gasses at high temp
silicon oil is a bit thick below 0c

so have been looking around for a good one

so far im looking at this one Envirotemp 200 Fluid for the cold side , and might just use radator additive with water on the hot side

also been playing with the pelitiers , seems to get colder ( more ice build up ) with the double stack wired in parallel ( 12volts 2 amps ) rather than full pelt at both 12volts 4 amps in series , 1/2 the strain will be good ( they will last longer ) but the hot heat sink is over heating on my test rig , thinking about PWM thermostats to drive these , so i can have hot side limits for each back of4 doubled , move of a voltage control rather than a amps

i was looking for heat sinks , not much available

we have aluminium lover blades at work that are hollow , so i took an off cut home to measure up and CAD , and a 48 peliter stack is too long

but should be easy enough to make

started to cut some "heat exchange fins" today

i get off cuts of aluminium " louver blades " from work , but i dont have enough to make all of it

Keep it coming Ken
I'm really interested in this. I considered doing this myself once but in the end I just couldn't be bothered.
If you succeed I will maybe try again.
I'm not really sure why you are bothering to insulate everything. i would have just sunk the whole lot in the oil.

insulation is coz im gonna try and get the tank below freezing , and i live in the tropics , condensation is a bastard ive seen set ups on the net running at 4.2ghz with just dunking in oil ( over heat 24/7),. im gonna freeze the crap out of it , just coz i can , and push for 5ghz

im looking at 50mm thick 2 part foam , filled after tank is made ( with lid ) but the top section will sweat like a "southerner on a beautiful Darwin day " , so i might have to make my own fibreglass U shaped fitting around the top of the tank and lid , coz aluminium just wont do

ill post all my cad drawings i cut
working on my CPU cooler at the moment , i was going to go a water cooled block , but thats for water , i dont need an exhaust port , i can just let the juice escape(?? might save my self $40 and spend 8 hours on it ????) , and have 1 inlet , no outlet , it will help with the flow , looking at home made cooling block for CPU , RAM , and 2 GPU's running off 2 pumps ,2x2 spit , i figured out i can mount " intake " tubes off the heat exchange , and mount the pumps on to the draw , so they slot in nicely once the draw is shut

pulled a radiator out of an air conditioner this afternoon , its friggin huge

like i said , "this might take a while "

>???? properly give it too my brothers kids , after im done ??? 80% is just bits i have laying around , 10% off cuts from work , dam i have too pay 10% ??? W T F

this post is because the PC manufactures have hit a brick wall when it comes to speed , they cant make the crap inside the chip smaller , coz it wont work , so are multicoring so we bye new ones , the difference in a 2.8ghz I7 and a 3.4Ghz i7 , is the size of the heat sink , so they " turbo it " for 30 seconds untill it over heats , to get the most out of it ,. they have 2 options , cool the crap out of it , or change from binary to "oct bits" ( a chip with 8 stages between 0-5volts instead of 2 ) running each 64bit instruction through 1 wire / ram memory in a 64stage/5volts system will only bring a 6 log increase in speed ( good for the same growth over the last 10 years ) BRING ON THE AGE OF THE MEMRESISTER CPU's & RAM ( mono pole magnets might help ) , any decent multicontroller can run 128 switches off 1 wire , 256 really pushin it ( a different resister for each switch and a 8bit ADC )

and i want my next PC to instant boot its operating system " windows hard wired into the chip " , want an upgrade , bye a new chip , like old tv's , hard wired , not software , windows knows it has to load VGA, 2 drives ,sound , and its a " legacy" that it has too boot ," the unix guys will shoot me now " , so just go out and bye a instant boot unix chip off the china ripoff makers , dam carnt even email JOB's to get apple a 5 year head start , ??? google might do it ??? bill gates is too busy trying too bye a global peace prize too care
my 2 cents worth , pity its rounded down

i can see liquid helium cooled PC's to double the Ghz , its the only way , more cores is crap , software only runs on one core ,. i have 2 tesla's if i want more core's
"c++ cuda" code is great for number crunching , but spends way too long waiting for an answer from a different core , before it can proceed , multi core software is a big hassle for programmers ,

cheers ken

You are bonkers. But I like you!

insults just bounce off
TY tea lady
how's the turnin going ?
