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.

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?

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.

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

That's what she said.

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.

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

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
