Very nice project :)
Well fellas, this is the best I have done so far with my ghetto chiller:
http://service.futuremark.com/compare?3dm05=1686680 :D :D :D
Not bad at all, I must say...
Damn nice score :cool:
I'm surprised the pump can live with acetone. So what core temps can you run on GPU now? Have you tried upping core voltages and then adding the acetone?
Nice results Ply:clap::clap: Ghetto but quite Xtreme!!:D
But the cpu could'nt go any higher with the extra cold?

Don't mean to revive an old thread, but I really liked ur technique... Do you have a current project like this again for your x1900? :)
Nah, my 1900 is a dud on the core, max 729 with water. Memory is really good though, 900+ with tweaking. Gonna wait till the next upgrade to play around some more...;)
Nice ghetto system m8 :)
What kind of voltages for 729?? Mine hits 675 max with 1.35, and won't even do 800 on the memQuote:

Is there anything special to look out for in a pump that can handle acetone?Quote:

Has to do with the materials it is made from. I think the pond pump I tried was made from abs but not for sure on that. Got it from Lowe's Hardware store.
Delrin is fine with acetone, and I think Norel and Nylon is too but not certain on that.
Acetone likes to eat a lot of stuff so I would double check pumps materials before running acetone through it...
Ply i'm finally coming for ya http://www.xtremesystems.org/forums/...d.php?t=103927 :D
Very good.
I wait that you have not had any problem with the condensation, very valiant ;)
Lol, after seeing what you're "coming for me" with, I don't stand a chance. But may give yah a run just for kicks... ;)
I've used those cheap probes in chemistry. They are fairly accurate too. Only off by ~2c at temps of -5c actual.
If Acetone melts your plastic you can always try methanol too. It's available as automobile gas drying liquid (HEET). Be careful using HDPE Plastic under cold temps as it becomes very brittle and can crack easily if subject to impact. Delrin and nylon should be fine w/acetone but acetone will eventually eat through rubber o-rings. Acetone tends to soften even some of the toughest plastics after days of exposure. Methanol may be less abusive to o-rings. Acetone will really eat up any acrylics, polystyrene, PVC, and I think polycarbonates.
i like ur data scwam. ur oding chem r you?tis nice to tlak to osmeone in the know. im at uni oding a masters in chemistry and i ahve ofund it very useful in the extreme cooling world,:)
Thanks, unfortunately, my chemistry wasn't accredited by a college or even legal when I was doing it but I enjoyed the hell out of it. Especially having to know about what solvents go with what plastics. I found the whole precision of chemistry really fascinating, and see the results of my own work was rewarding. I remember one chem: P-benzoquinone, man that stuff is really nasty.
Thread necro here. Just updating the pics...
Ply
excellent Plywood99 i really enjoy seeing stuff like this.. gotta love your ghetto setup :up:
Thanks for posting the pics Ply. :toast:
this is great good on ya dude
love the setup
the only thing i am surprised people are still not insulating components and also waterloops and blocks >> you should probably do it to avoid killing it prematurely
Yeah insulating is always good advice. When I ran this loop it was really cold outside so I put a fan in the window and kept the room closed for several hours to reduce temps and humidity. Room had to be around 5c if not colder.Quote:

P.S. Hopefully Amd will have something on the table to play with this winter. If not I'm movin to Penryn. Been loyal to Amd for a lonnng time, but I need to have some fun...

yak..:eek: good job it very nice, i'll try too :D
