Absolutely incredible. I'm more of a fan of 100% stable OCs, but this was just damn impressive. Well done. Shame the board crapped out...

Great read, Agatha Christie style :) Even the end was not what I expected :(

xtreme experience... great fun I imagine

OH!!! And slightly OT, when I got home last night I threw my x800xtPE in my 24/7 rig to make sure it wasn't the problem and noticed it's quieter than before the bath!!! Seems that the oil re-lubed the fan, lol
C

see even with some possible dead hardware... theres always a plus side...

dont have to lubricate your fan :hehe:

great work charlie... some interesting results... and should make ocing WR's a little more fun dont ya think... lol

i remember hearing about some fluids on the screensavers a year or so ago... maybe it was an alcohol because they were worried about evaporation... but they had submerged a system into some fluid and were running without a heatsink... maybe this is the same stuff... im not entirely sure...

what about building make shift dam's to prevent certain areas from freezing... if that is an issue... im sure most components can handle the low temps

and are you sure your "icecream" was frozen oil and not possibly condensation or anything like that... maybe air pockets under the cpu socket... i dont know...

good stuff buddy... hope ya get this setup up and running again and get you a WR! :slash:

truely xtreme. That might just be the coolest thing ive ever seen.

i really wish you break WR soon....you deserve it :toast: (and i hope your FX55 isn't dead.... :( )
the most interesting reading i have seen in quite some time.... :up:

Awesome work Charlie. The most extreme experiment which gave the best read for a long while this is!! :YIPPIE:

Thanks charlie. Great try and fantastic presentation. You'll get the WR.

Deserves the WR after this extravaganza.

Sometimes I wanna be an engineer for those places :D

I agree. San diego and Venice will do it :D. Νιce work Charlie :toast:

Crazy stuff, Charlie :slobber: Submerging that mobo in oil was Most Xtreme of Xtreme :thumbsup:

I hope that it was $130 Neo2 that died and not the $900 FX-55....

WR? You'll get it sooner than you think!

Am I the only one that sees this as great idea, or just noone like it?

Take a submerged PC and use the tank like a water-chiller resevoir?

Freeze the tank with the cold from a phase-change system?

I think it would look pretty cool! :cool:

He's right, although ethyl has better thermal conductivity (I know methanol has the best thermal properties, but it's toxic sh_t, not worth going blind and not being able to see your 4GHz screenie :lol: ). BTW, the best (cheapest) source of ethyl is Everclear. Illegal in Cali and many states, but I've bought it in Tijuana, back in my college frat days, to make "Red Death" for parties.

I was thinking, why not load up your submersion fluid (IMO, alcohol, since it won't freeze) with dry ice "cubes" to lower the temp of the fluid before introducing the LN? That way, your fluid is pre-cooled and shouldn't add as much heat to the mix, plus your board is cooler all around. I'd just submerge the whole thing, GPU included (without fan).

BTW, have you seen this submersion thread?

lots of everclear up here in canada lol

That explains a lot.

dude, the point of the oil was insulation, mobo components can't survive very cold temps

Awesome! Better luck next time!

heh

but seriously, i'm sure you could get closer to 100 percent ethanol than everclear...though i guess everclear is cheapest.

btw, for those in the know, what is the diff between ethyl alcohol and denatured alcohol?

Just a note, I used OIL to protect the board, not to freeze it...the -10C temps were just a bONUS ;)
Plus, I didn't want anything stinky or toxic or whatever...
I've had the board standing on it's side for 24 hours now, and it's still dripping!

Dude, the point was insulation from condensation. Mobo components can't survive frozen water on them. :rolleyes:

Yes, I know caps explode when too cold, but at least read the thread starter's reason for the project:

I do think one has to pretty much assume that his mobo is hosed with a project like this either way. :lol:

Yeah, but it's highly regulated, and you probably get on some terror watch list if you go the chem supply route. :lol:

lol... yeah, tommorrow I'm going to grab a can of brake degreaser or some dielectric degreaser spray and see if i can't clean it up :D
