Anyone feel like linking me to some literature about how these things are held over the processor, and dimensions?

I have the ability to make a pot and all accompanying parts now, and I intend to do so. :Panic:

You expect someone here to be able to help? If you have the ability to do so you probably have as much knowledge as we do. At the very least you should have the ability to google.

Tongue-lashing as, let us know how that goes, I'd be interested to see the results.

Heres a good article.

From ambient to SUB-ZERO - Overclockers Forums

I'd give more info but I'm studying for a test.

great!

I'll start drawing up some plans tomorrow, will keep you guys posted.

And, I'm not really much of an overclocker... (I have one sempron running at 3.8 GHZ with both cores unlocked, on the stock cooler... that's it.) but I really wanted to make a dice pot :)

the thing is that you need to determine what kind of pot you want to make, ln2 or dice.

ln2 needs lots of mass so that temperatures dont swing as much, while dice needs lots of surface area to lower temps. Most ln2 pots can be decent at dice, but dice pots are usually extremely terrible at ln2 due to the huge temperature swings that occur.

check out kingpincooling.com and look at some of his pots. they're generally regarded as the best.

Also, if you're looking at LN2, be sure to read through a lot of the OC forums on how to do it properly. And don't bump up the voltage/clocks too much too fast, I know that should be common sense, but I also know of a few people who took their CPU from 3.0ghz to 4.5+ ghz in just one go =p

what I'm thinking of is something somewhat unusual, the bottom will be square and screw into the top (the part that holds the coolant), and have it's own backplate and attachment mechanism part of the design.

I'm probably going to make it dice, simply because it's so much easier on the wallet.

I'll probably make the whole thing out of aluminium, but the portion that contacts the processor will be interchangeable, so it's easy enough to replace it with pure copper once I've tried out the design (copper, too, is extremely expensive...)

Another advantage of making it an assembly rather than one part is that I already know what pieces of scrap will fit in each spot, so I dont have to buy material. :rolleyes:

sometime the nest few days I'll have cad drawings, I'm terrible at explaining this stuff :p

I know it will probably make overclockers cry, but i'm going to use it on a $45 motherboard from newegg (asrock something) and a sempron 2.7GHZ processor... So no unlocked multipliers (I dont have the money to replace my phenom 2 X4 black edition... and i need it every day.)

The processor does go up to 3.8 GHZ on the stock cooling (stable for 3 weeks under 100% load... that being prime95, or bitcoin mining..(waste of time, i figured i'd try it though)) (with the second core unlocked) (although the lan stops working above 3.7 ghz) (and... I did have to replace the power supply after a (house) power failure during normal use... it was the one included with my $20 case anyway; no other hardware was damaged apparently.)

I have systems of linear equations to solve, see ya later. >_

Just make sure that the threads are going to be super-tight. Vince (owner of kingpin cooling) recently released a pressure-fit system where the top and bottom connected but that lead to tons of problems, make sure that the base is large enough where if you run dice there isn't a risk of there being overflow of acetone.

Ideally, you'll want a pot that weighs from 5-7lbs. Remember, that height doesn't really mater past a certain point. The base is what keeps/ maintains temperatures. Once it gets taller that only leads to greater chances of condensation buildup.

I'm going to make a class 1A thread fit (or so) OR i will shrink-fit the assembly, a well done shrink fit should hold until the whole assembly blows apart.

EDIT:

Actually, I've decided to press-fit the assembly, the way I have this designed it will not be able to leak, and any condensation on the top will be a non-issue.

I've got my basic idea down, time to start drawing.
