kiki's first "pot"

[kikicoco1334]

hello guys i know i have been out for a long long time, last time when i was here i was talking about making a pot with a good friend of my and here i am with it mostly done

now we are just waiting to seal the bottom cap (he can get it done 10 min ea lol)
and then i have to make the holders
that' can be done really fast

tell me what do you guys think?

here is some pix of it
it is 18in long and opening is 3in wide in diameter 100% Cu
is this too long? and/or the ass is too big?
this is the only one that's 3in in diameter and i think the others are 2in not really sure how long are they yet

Looks sick,

I have worked with 3" copper tubing. I am not sure if a 3" cap hsa enough mass with in it to hold temps .... I am guessing this pot will really have temp swings that may prove problematic ....

never the less I am in for the results

[GFDuke]

Yup i agree with Witchy on this. The base needs more solid mass.

[kikicoco1334]

how should i going by adding more mass to it?

Witchy is right! I have made like 5 or 6 pots on my own and I can tell you from personal experience that this thing will swing temps like nuts especially on quad-cores. What size is the pipe? 2"? If 2" you will have issues with installation on mobos where the Vregs are close to the socket.

[Splave]

toss a bunch of bb's in it

[FACE]

I was going to mention something similar.... if you could smelt down a block of Cu or even Pb (lead), and pour it down in to add mass, that may help. You would def. have the plenty of mass after that. If you could manage to get enough smelted, you can pour it in solid and drill out a bunch of holes for surface area.

Homebrew ftw.

[Hondacity]

nice home made pot :D

length id say 10inches..more or less...

[kikicoco1334]

hahahaha i actually have a pack of 3000 bb's in my house lol (bb guns killing shit in back yard)

wouldn't just dock it on to the chip?

i am not sure if i'll beable to find and cu or pb at all..
i'll see what i can do
but can't i just put some bb's in it?:laughing:

[FACE]

the material (whatever it is) needs to be securely fastened to the base, with no air in between for best heat transfer. The f1ee is less than $200 now, since there is a newer version out. It would be more effective to have a pot that is made from a solid piece of Cu. I like the homebrew idea, but maybe leave the length, make it heavier and use for a dice only pot. For ln2 I'd grab one from k|ngp|n.

[kikicoco1334]

i need to increase the mass of the pot got it!:thumbsup:

but what i dont understand is what is the difference between dice pot and ln2 pot?

[GFDuke]

Theres no difference. They're all pots for cooling. Some will cool better on Dice than on LN2. Some will cool better on LN2 than Dice. It all about materials and mass.

[Witchdoctor]

What might be effective would to take a 2 1/2" cap fill it with solder.

Put it into the 3" cap upside with the 3" pipe between the two
then solder the 2 1/2" cap to the inside walls of the 3" pipe to seal it off

That would give you significnat mass on the buisiness end ... I can illistrate if you don't understand waht I am getting at ....

As said earlier though 3" may be a bit large once insulation is introduced

[FACE]

That's what she said.

[HITandRUN]

Agreed! You need to make it out of 1 1/2" copper pipe to make it work.

Here some pics of pots I have made before.

You guys are crafty.

Homebrewed stuff is awesome and fun.

I vote that you just try it out as is. Then give the bb's a shot - you already have them (which is the same as free).

Sure the temps will swing, but you'll have fun. More mass at the base is great, but trying to add it to a copper cap is a PITA. Unless you're just having a blast doing the manufacturing, that time would be far better spent moonlighting for the cash to buy a milled pot from someone.

Taller is not really better. Copper mass way up the sides doesn't have easy access to the heat from the CPU.

[Splave]

its not optimal but would def help your mass issue :)

[kikicoco1334]

what about adding one of this in it?

Both ideas may give more surface area but will not really help with "mass". The reason the F1's mass is great is because it is from one solid piece. With multiple pieces your limited by the heat transfer between that big piece of copper and the base. It may help temps slightly but not much.

Guess you werent around for the 3" Mousepot

[Neuromancer]

Looks up with binoculars.

Yeah you guys are WAY over my head.

I do agree solid chunk drilled out should be better. I love DIY though :)

Mass = better, thats what I read. and the F1 pot Kal let me borrow got rid of that nasty 40C swing Dicing wPrime... trick is MASS alone is not enough. Need to get surface area, or you "cold substance" is not removing enough heat. Too small (say fins in the bottom) would be a problem because they would get brittle and also clug up with condensate.

Rods like an old ram sink might work decent, but too hard to mill unless its a two piece...for DIYer though... its an option ;) especially with 3" diameter to work with ;)

Use some thermal tape a bunch of copper ram sinks (old style 1-2" high kind) torch it to melt the tape and get to freezing :) Just an idea...

[lesstutrey]

difference between a dice pot and ln2, mass. A pot good for dice has less, a pot better for ln2 has more. Why? It's the temp swing mentioned above, if you have a pot with a ton of mass (like say.. 5+ lbs) that is one piece temp swing becomes much easier to control with a very cold liquid (ln2) but with dry ice you don't have to worry about cold bug generally speaking, so if you had a ton of mass you get too much for the dry ice to cool, let alone keep cold with cpu heating it up. You need less mass because of the conduction of heat.
With dice you also want a lot of easy to access surface area (think of the f1ee extension piece) because the more area the dice has to contact the more ability it has to cool, but it's not as nice an easy to make contact with as ln2. Also since no cold bug you want that thing full of dice the entire time, as much dice as possible. Think of how elaborate patch's base is, it wouldn't work that great with dice because dice isn't gonna flow through that small of holes well, the acetone may, but it's not at the same temp as the dice, slightly warmer. So a good dice pot has a medium amount of mass, a lot of surface area, and lot of area for the dice.

And yeah, my pot is fuggin huge (about 3" diameter), and i had to cut into the insulation to get the pot to mount to 775.

[FACE]

That Otter pot is a beast.... If I had one, I wouldn't want to use it! I would cuddle with it instead (and try not to drop it on my foot). :ohcrap:

[Neuromancer]

I have almost no experience with POTs... I do know that an alum light weight pot was not as good for dicing as Kal's F1 EE he let me borrow :)

40C temp swings in wprime on AMD chips is redonkulous.

However, tests showed the Koolance V2 is a better DIce pot than the F1.. (or course it is not much better and when LN2 is added the F1 is much beter...)

They both have similar styled bases drill a bunch of holes in the bottom... just the koolance is lighter and nickel plated...

I was also told NOT to fill up the pot with DIce. So I did not with the F1... that might have been the difference too.

[FACE]

Indeed... DIce should be used sparingly. It is easier to stir, and allows the acetone to do its thing better and not all over the place i.e. the board, gpu, your face, whatever. Plus it lasts a LOt longer. You can make 25lbs of Dice last all night, baby!

I personally have only used an f1ee pot, and found my best results with DIce temps being very little acetone (not quite filling the holes) and 1/4 to 1/2 cup of powdered/SMALL chunks of DIce. Yeah, I used a measuring cup... just like Martha freaking Stewart... :laughing: As long as that mixture is kept the same, the amount really shouldn't matter. Temps wouldn't change any though, as I was holding temps below -68 no matter what the load was, and had min. temps @ idle. The only downside is you end up scooping a lot, but the control you have is amazing. :thumbsup:

ln2... well, I'll get around to that one of these days. ;)

[Bobnova]

The key to dice IMO is crushing the dice before you start benching.
Little tiny pieces (think coarse corn meal, or standard aquarium gravel at the largest) to snow is best, by far.

I like to put about 3oz of acetone in my koolance v2, that way if i can see the middle bit i know i need more dice.
The dice/acetone mixture should be just starting to feel thickish when you stir it, like a 75% melted McD's milkshake with some sand in it. If it stirs like water you don't have enough, and if it stirs like mud you have too much.

The big chunks you see people use are an excellent example of doing it wrong.



Bonus tip: Boot warm with the pot attached, then put powdered dice in till the temp sensors bug, then put a tiny bit of acetone in, more dice, tiny acetone, more dice, then acetone till you have as much as you want.
If you put acetone in first then dice, or throw a lot of acetone on the dry dice, you'll get an acetone/dice volcano. Not good, the acetone'll eat your keyboard, face, eyes(!!) and probably motherboard, and dice in the eye is a fairly major problem as well. Personally i stay way the hell away from the pot when i put the first acetone in.


Oh yeah, if you want to add mass to a dice pot, get a .25" thick copper coldplate from anybody that'll sell one to you and put it under the pot. Presto! More mass. Also helps fat bottomed pots (like the koolance v2) clear tall caps near the socket.

You forgot to add "Expensive wooden office furniture finishes" :laughing:

Not to mention your lungs. Have a fan nearby and blowing at a window fan drawing the fumes out of the room. Its bad, very bad.

So, it can ruin everything you love and is definitely not good for you... no wonder it's so fun!

Again this statement is totally untrue it will not add mass and will not help temps all that much. It may even hurt temps.

[Splave]

i def helps with SS and cascade under the same principle why would it not help hold a load on a tiny pot?

I looked for that thread but cant seem to find it. I do remember that discussion and the results were good. (not from my experience, as I dont have a phase change but reading other members daring-do)

[FACE]

It will help, no doubt. but a 2" block under a 3" pipe cap, i dunno. You'll have to be really anal on the insulation.... make sure it fits perfect under there, or it's frostville in the worst spots. :thumbdown:

[Bobnova]

How does adding copper not add mass?

[kikicoco1334]

or should i just get like some of those copper rod on ebay and drill from that?
