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 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.

Mount your pot snug
check insulation around base of pot/cpu socket
power on motherboard, enter os, check temp readings
put pc under load while monitoring temps (wprime is good)
Look for temperature delta at load between POT temp probe and software readout
If temperature delta looks good and normal then you have good contact/mount
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
Add more DICE (be carefull of volcanoe acetone, at first acetone is room temp and may volcanoe out a bit as it cools)
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.

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
