I use denatured alcohol...I would think about 15 lbs. would be enough for the first go. It does not keep well.

• 10 lbs should be good for a nice session
• Usually comes in a plastic bags or pellets
• I use a fat head hammer to crush into dust while still in the bag
• pour a bunch of crushed/dusted DICE into a wooden bowl and use a table spoon to feed the pot
• DICE submliminates rapidly and does not keep in your freezer at all. Any extra will not last two days.

1. Mount your pot snug
2. check insulation around base of pot/cpu socket
3. power on motherboard, enter os, check temp readings
4. put pc under load while monitoring temps (wprime is good)
5. Look for temperature delta at load between POT temp probe and software readout
6. If temperature delta looks good and normal then you have good contact/mount
7. scoop a few spoons of DICE into the pot, pour a small amount of acetone (just enough to be 3mm above the bottom of the pot
8. Add more DICE (be carefull of volcanoe acetone, at first acetone is room temp and may volcanoe out a bit as it cools)
9. Start clockin.

If you are using alcohol instead of acetone, you shouldnt get as much volcanoe action. ALcohol will vapor off and you will need to keep adding for time to time more than with the acetone. Alcohol will gel up at the bottom so make sure to use a screw driver to mix it up down there.

Depending on your insulation, remove the pot as soon as possible after benching, remove the cpu and let the socket area dry out normally or use a hairdryer. (I use compressed air after my dice/LN2 sessions)

You're saying to do this temp delta checking with no DICE in the pot?.....And do you mean 3mm above the top of the holes/bottom of the pot?

Yes
and
Yes

I always check the deltas to see if the pot has a good mount. Going forward with a bad mount will get your cpu cold but under load it'll crap out and could result in a damaged chip during one of those spikes.

I say 3mm above the bottom of the holes because you just need the DICE at teh bottom to interact with the acetone to make the base cold. You save tons of DICE this way rather than liquifying all your DICE at once.

Great info!! Taking notes....

Check what I added to my sig, lol :)

OCM :thumbsup:

Cheers :thumbsup:

So fill the holes with crushed DICE and then just barely cover it with acetone? Sounds easy. Thanks for the tutorial! :thumbsup:

Thanks. Gotta start somewhere.

Two ways of doing it, fill pot about half way and guestimate the amont of acetone that would fill holes and cover about 3mm of bottom (this reduces the initial volcanoe effect)


and fill holes, scoop dice in and pour a lil more acetone till 3mm.


No volcanoe, fill pot with DICE, pour acetone

Sweet, thanks again Kal.

I could actually measure out the first dose of acetone so I know exactly how much I need. I'll just setup and plan for a volcano to happen though so I don't end up mad with the stuff everywhere I don't want. :D

I usually have a rag handy to cover the top during the temp drop (volcanoe action) pour and cover tactics

I buy 20+ pounds for a session but I run each test 10-15 times...

Use what is available to crush. I have a 5lb maul.. I hit it with the big side of the head not hte striking side.

I put a big old block of it in the bag its in in the shopping bag and then put it in a contractoers bag. (3Mil min) then beat the piss out of it. Done it on the driveway too made little difference except you can easy up the work by just throwing it a few times :)
I also dont use a bowl I use a cup that I keep in hte cooler with the crushed ice in hte bag squashed up to preserve it...)


Not saying I am right or Kal is wrong... just some differences. salad bowl just seems like too much surface area...

Everything else is spot on. Don't matter if you use a snocone maker to get your DIce snow... long as it is snow :) And the rest is awesome sauce :)

So DICE snow is better than little small pellet size pieces when dropping it into the pot?

Finer works better for me.

doesnt have to be snow per se but smaller the peices the better. The acetone or alcohol serves as the delivery medium for the cold offered by the DICE. The purpose of the Acentone/Alcohol is to maximize surface contact area at the base of the pot. Acetone gets cold, whatever it touches gets cold. So when you have DICE in small pieces or snow, you can get more of it to contact the acetone which results in cooler temps. If some of that snow actually gets down into the holes of the F1, EVEN BETTER!

Stir often to make sure the DICE is gettin to the bottom of the pot.

Finer = more surface area.. You can fit more sand in a container then pebbles right? Same idea.

Remember you medium is liquid....

EDIT: yeah what supes said :)

I was using different size chunks of DICE in my cooler and notice that the bigger they were the more I had to stir with a long screwdriver. Smaller pieces were much easier do deal with.

Interesting would think larger pieces would be more effective in that situation.. Not cooling wise but manual intervention wise...

I am a n00b for a reason I guess though :)

It is DONE! Another Overclockaholic convert

Buwahaha! Its so much funner over here on teh darkside, ya buddy!:clapping:

Point of no return.

Welcome.

Had a blast over at Kal's yesterday. Felt like a kid in a candy store. Poured my first thermos full of LN2 and heard the Dragon hiss for the very first time. What a rush.

Scrapping the chiller idea and jumping into LN2/DICE head first. My pot will be here by the end of the week.

Hi, my name is OC Maximus and I'm an Overclockaholic.

Thanks Kal,
OCM :thumbsup:

w00t kal was telling me you were heading over :) awesome man, welcome

Way to go mate! Get cold NOW! :D
