Since yesterday, I've been fooling around with some dry ice (DI) and a pair of chilly1 DI containers. Here are some pictures and screenshot of what happened



The money shot


Ice cold coke in less than 30 minutes


The key to a successful sub-zero cooling is the insulation so I started by coating the back of the motherboard around the processor socket with some liquid electrical tape.


The same thing was also done to the front and back of the graphics card



Next I applied some foam insulation tape on both the front and back of the motherboard and graphics card.

After all the work insulating the graphics card, there was some problem with the mountings. Due to the rapid dwindling of my DI supply, I decided not to waste anymore time fixing it and went ahead benching with DI only on the processor.

After I'm done benching there were some DI left and here's what I did with them

DI + hot water + soap


DI in the toilet bowl

awww, c'mon arj you didn't do us justice!!! what's the cpu temp!!, i wanna know wheter the sub zero bugs with the venice has finally been sorted.

By the way.. WOOOWWWW man 3GHz !!!!:thumbs: congrats,

O.T.: now i've got the chill to take a crap in the toilet bowl

having fun i see

so when ru trying on the dfi and some xtreme ln2?




also...the liquid electrical tape (red goo) can peel off/remove once ur done?

I was rushing just now because there's only a few block of DI left, forgot to stick one of the thermocouple on the base of the DI container

The bug is still there but you don't have to worry about it unless you have a tripple cascade.



Kinda lazy to take out the DFI from the case, clean up the dielectric grease and them put it back in the case

No LN2 for me, too risky




A'ah, dah ada rancangan

so that brush on electrical tape.. does it just come off by peeling?

Yup, peels off very easily

Yup i second that, , tried and tested.. no need other solvent or chemical.

LN2 not only dangerous to u but it kills the proc and mobo efficiently also..
Arj if im not mistaken, DI wouldnt be enough to cause ice to occur all over the mobo..So with proper insulation like master arj just shown us here..Ur hardware is quite safe..

Haiya i got slow streamyx connection today, some pics dont show up..
Im dissapointed..

Btw, congrats 3.2Ghz is just awesome..
Lookin at those step by step pics, it motivates me to put my winnie under that DI..

I know winnie had subzero bug, but u might never know..

Hmm but those containers, How much u got them for..
and all those stuff such as electrical tape can be obtained from normal hardware shop?

Both of the containers costs more than the processor

Yeah, they all can be found at good hardware store like Ace Hardware.

// arj : do you DI your vga card as well???

Evogenix

Nope, not this time.

Tripple? woaaa... we're talking more than -30C here..., well than i guess the bug is partly sorted.

yeah PCcrazy, you'll never know unless you've tried.. neway can tell me where can get those liquid nitros? Need special license or permit to get hold of em?

LN2, im not sure cos normally its not accesible to consumers..
Its just like all those acids and chemical stuffs..
If u happen to know somebody working at science lab, i think this might come handy..
Hmm, maybe i jus give my buddy a call and try asking if he could get his hands on LN2..

some funny thoughts to share..

Dry Ice Obligatory Warning
Madshrimps ©

Carbon dioxide is heavier than air and it can concentrate in low areas or in enclosed spaces (like a car or a room where dry ice is sublimating). Normal air is 78% Nitrogen, 21% Oxygen and only 0.035% Carbon Dioxide. If the concentration of carbon dioxide in the air rises above 5%, carbon dioxide can become toxic.

Arj, u sure u r not toxicated
Any clue where did u get those big blocks of DI..

Three stage cascade can easily do -100. The cold bug is around -90 if I'm not mistaken



Damn.... I'm having a terrible hangover right now

I bought the dry ice for RM3.80 per kg from a place in Shah Alam, somewhere behind the aquatic center. I got their contacts from Baskin Robins

erkkkkk more than -100C!! the most i can dare is a single phase system.. temp around -25C~-30C.. .. even Fugger's dual stage cascade scares the sh@t out of me (-100C!!).. sigh.. i wish bulkhy can come out of retirement and help me out on this one , neway this is after all about D.I... a little bit off topic ere..so arj wanna start a sub zero club? Anything that can cool below freezing point can discuss and shared with all LYN's own Xtreme Cooling!!! yeah

ON TOPIC: CO2 is poisoneous if the concentration level reaches 5%, symptoms of CO2 poisoning after prolong exposure to a highly concentrated CO2 environment are:

1. Drowsiness
2. Vomitting
3. Discoloration of lips & fingertips
4. Morning sickness (mebbe i've got mixed up with this one, is it pregnancy or poisoning )

Remedy, rest in a good ventilated room for 12~16 hrs taking plenty of fluids. If symptoms still exist, go find a bomoh.

how long does the dry ice last before it evaporates..

That's the three stage cascade

A block of around 250g can last about an hour if you just leave it alone outside the icebox. You can bench for around 7-8 hours with 10kg of DI

10kg D.I. how much the cost ar?

Oh thank you for showing the link, sorry, the dual cascade that i meant wasn't fugger's, its this oneVR-Zone DIY Dual Cascade Vapour (they got help form Chill1 and the crew).. .. yup i'm into diy'ing my own phase cooler (slowly.. very-very slowly ).. wish me luck.

MOX sells liquid nitrogen, called just now for fun saying i need some ln2 for experiments. they have sales centres throughout msia - http://mox.com.my/contact_us/mox_sales.htm

they dont rent out dewars (container) so must buy it from them...sizes are 4L or 10L

they said will fax me a quote for the price of dewar and ln2 so dunno the actual price

better read this before playing with ln2...
