dry ice

post #1 of 8
Thread Starter 
going for a suicide run on my 3000+ venice and trying to break ncsa's stable oc and to compete ive had to go the peltier cooling way but is just not enough, made 3006mhz but need a tad more cooling to kepp it under control, will dry ice in a tube sitting on top of the cpu cool it at all or just simply wont work, this is just going to be a 1 off experiment to see how far you can actually go.

I've seen something like that done, although they were sucessful w/it for a little while the cold actually damaged something and the computer just stopped working. Although they let everything come back to room temp and the CPU still worked, it was the mobo that died. Good luck w/it though.

Capacitors stop working when they get too cold because the fluid inside them freezes.

Well, DI/Ln² cooling requires ALOT more then a simple drop on a tube and pour in the Dry Ice.

First of all, You either need to make your Tube, Or buy one thats been professionally made (roughly $100 USD+) and mounting kit ($15 USD+) and all the di-electric grease and stuff.

THEN, Once you've got it on, Depending on how much DI you have, Your time will be pretty limited.

I'll google around and see if I can find some good guides.

Yeah, Yiffy, Its when they hit -30° or lower the caps start to get all messed up.

thinking of a cardboard tube not unlike a toilet roll tube but longer and possibly getting wider as it gets longer to just hold more DI
Dry ice is easy for me to get and not expensive, if i can keep it to only the cpu and just load the mobo up with grease and silicone spray for waterproofing im thinking i could be able to keep the freezing under control.

lol tuchan, i talked my wife into getting me a ln2 tube, but after she learned what i was going to do w/ it, she promptly canceled the order i was gonna go for a suicide run on a 3000+ venice too. biggest thing, mix it w/ some good alcohol, acetone works, but everclear i hear is better....(for dICE) otherwise, get your hands on some ln2, because i hear thats how they get the coldest.

I tried some dry ice cooling once. It wasn't a very planned out experiment but i got my cpu down to about 5C by dumping the dry ice down into my heaksink (with the computer on it's side.)
