Default extream cooling for science project

i want to do ether a liquid nitrogen or dry ice cooled comp for my science project but idk how to do it
could some one tell me the steps
(i would like to over clock a Intel core 2 duo e6600 to at lest 4 - 5 ghz(7 if possible)
my exsperement is to get a very high clock speed
1. should i use dry ice or liquid nitrogen
2. witch would be cheaper
3 witch would offer better performance
4would dry ice melt while trance porting?
5.what materials r needed
6. wair can i buy dry ice or liquid nitrogen
7. does is work any way like liquid cooling
thank u

i dont think you can buy liquid nitrogen or dry ice but talk to your science teacher about that. This idea doesnt seem like a good one for a science project but thats just me. And i dont think that processor will OC to 7ghz at all.

you probably need some sort of certification for buying it and using it because its dangerous and youll need to know how to handle it so you dont freeze a finger off.

ok for a start , liquid nitrogen is at about -195 c , i dont remember the exact figure but it is around there and so safety is of the essence ,even dry ice can cause frostbites , and remember it is still carbon dioxide and so can be toxic in high concentrations in air

i dunno if 7ghz is gonna be possible , cos although the cooling may be good , the core may not be physically able to handle speeds of 7ghz

see this and watch the vid for more nfo on cooling http://www.tomshardware.com/2003/12/30/5_ghz_project/

as for prices , dry ice would be the cheapest

all i can say is stay safe

im prob using dry ice
and liquid nitrogen is extreamly cheep u cna buy of the net
and use special containers that cost 30 bucks to carry them

the liquid nitrogen might be cheap but the containers they come in is probably where the price racks up.

yep certainly , you cant just put them in any old container you need a dewar

heres some more safety info http://www.2spi.com/catalog/instrume...odew-supp.html

if you where in the uk your school would prolly have to carry out a risk assesment and you would have to be supervised by a member of staff at all times , hell if you where in the uk you may not even be able to handle the liquid notrogen , i dunno how american schools are but i am sure there will be simmilar health and ssafety ruling

I believe the record is 8.17 GHz, HERE is the link, but I'm not positive it's current. All of the extreme overclocked rigs use LN, at least the ones I've seen. If you want to get above 4, use LN, dry ice wont last very long. When you pull it off, post your specs, I would like to see how you do. I'm not sure if you can just put LN in a water cooling system, the tubes would probably freeze, crack and leak.

Just a side note, this will probably damage you computer, don't plan on using it ever again.

Edit: LN cooling tubes http://www.maximumoc.com/ln2.html

im going for the record of a quad core (10 ghz if possible stable) imagine gaming with those speeds!!!!
me and my friends r ganna do it
were ganna go for a insilated copper tube
hope to get 10 ghz =) can only hope
what graphics card should affect over clocking right?
just got to get a really good power supply and some nice ram

you would probably have to add the ln at the right time or the core will be too cold to even start up.

the cpu will start up just fine
has no moving parts
electrisity cant flow threw appsilute zero
liquid nitrogen
is a couple deggres hotter

Reminds me of when we got to mess around with LN in chemistry. You could put it on the backside of your hands and it would slide right off. It evaporates so fast that it creates its own pillow underneath itself letting it slide all over everything.

Didnt' someone in Japan or Korea OC a pentium 4 to 7GHz cooled by Liquid Nitrogen? I never saw info reguarding, a friend told me. Don't know if its true.

looks lagit http://news.softpedia.com/news/7GHz-Pentium-6202.shtml

I'd use dry ice. Liquid Nitrogen, if handled improperly, can be very dangerous. If you spill a bit on your arm, you will probably lose it.

Yeah go with dry ice. It's easier, and it's going to be safer too. The performance isn't going to be as good as with LN, but it's still going to be great.

That tomshardware thing should give you quite much info. One thing though, if you are using dry ice then you will want some form of liquid into the tube together with the dry ice. (probably something that transfers heat fast)
