Final revisions before milling?
 

Many have seen my WB drawings but here is the most recent and maybe last draw-up. Is there anything you would change? Why?

WaterBlock

why 2 11/16ths" ? You'll have the socket hinge area to contend with. Do the same thing in 2". Saves copper and machining time.

The "height" is 2. The other dimension: 11/16" is for the heigth of the chanel. :) it's not that clear i guess.

What he's saying is why not make the block only 2" wide as apposed to 2-11/16" as youve drawn...

then you wouldnt have to deal with milling down the top side of the bottom of the base to accomodate for the part of the socket A that is raised up on the top part(above cpu)

Re: Final revisions before milling?
 

Only one thing. Did you think of the offset? Make sure your center barb hole is 3mm to the left of center. The die doesn't sit dead center as you would think. I made that mistake.

Yes liquid rules, I know what he's saying. And what I am saying is the block will in fact be 2" wide. There are two seperate dimensions, 2" and 11/16". Both are side by side, but they are for two seperate measurments. It might apear it is 2 11/16 but it is not! 2" is for the width. And 11/16" measuring the width of the chanel (there are 5 fins and 6 spaces. Fins and spaces are both 1/16". 5/16+6/16 is 11/16.)

Sorry about the confusion. Hopfully you all understand now.

Sorry , I see what you mean now. My apologies.
It looks alot like the block I made awhile ago. Performs excellent.

I beleve its more like a 1.5mm offset from the center..... its .0539 inches I think.

From the socket yes because of the lever on the side of the socket. From the mounting holes it's 3mm. Then again I seen some MB way off that amd spec.

Solidworks
 

hey, that's a nice little drawing of a socket in solidworks there... any chance you can post the assembly file?

Re: Solidworks
 

Yeah, I dont see why not. I got it from Utabintarbo...so it's all his hard work. Even includes a Palamino too!
Sure makes it a hell of a lot easier to model a block and see what it looks like when put on the MB.

EDIT

I sent the attachment a few times but for some reason, it wont show up in the post. Maybe its too big. The whole assembly file is 3.3 megs......
Strange indeed

The limit here is 75 kb...

The little box behind the socket is called the "cam box" (that's what they call it in the AMD docs) and yes, any waterblock must have a groove to clear it (if your block runs over it) othewrwise this cam box may prevent the block from sitting right.

Well that would explain why it wont post then.
Maybe you could PM me with your email and Ill send ya the assembly file(s) for the amd socket and palamino??

I beleve its what I stated, were do you see the 3mm? where did you get it from? I have just measured a block I made to acomidate this offset, and it seems to be rite on.....

What do you mean "it won't post"? Did you fry it?

You can find the Socket A specifications here (from AMD, doc# 23794, PDF, 30 pages)

Look down in this thread. I didn't think it was that much either. Who knows. I can't find anything about it from amd yet.

I thought it was 1.5 mm:confused:

1.5mm and 3 are both correct, depend on what you measure.

If measuring from the center of the socket, the holes on one side are 3mm closer than the other. That means that to get a centered nozzle, it need to be offset by 1.5mm, as the difference has to be shared.

Lol, stupid question, but assuming that you have an asymetric waterblock, is the core 1.5mm more to the left or the right when looking straight at a standart socket A mobo?
EDIT:
And actually, according to AMD spec sheet, the offset is 3.5mm, that is you'll have to move the center of the waterblock over 1.75mm to the left! :)... Now follow me here: Moving the center of the waterblock over can simply be done my moving the mounting holes on the block over to the right by 1.75mm....
CLEAR? :)
(Don't think I just thought all this up... I used solidworks to make my own schematic sketch)

Cam box
 

Just to clear up this cambox issue, if I make a waterblock that's 2 inches wide and mount it centered vertically using the four motherboard holes, it will not interfere, that is I will not have to machine out the 2mm deep groove on the top that AMD specs for heatsinks?

I always use the mounting holes and measure in to the center accordingly. If you make the block 2 inches wide you should clear the socket cambox. Anything wider and you'll want to take 2mm shaved off one side on the bottom.

Actually the official AMD specs state that for Socket A, the CPU die is 1.27mm off-centre.

If you're really interested, all the information is publically available at AMD's website, including forward looking mounting specifications for Hammer, etc.

How much off center from the mounting holes? That's what I'm trying to find out as AMD specs is just state the socket it self.

A CPU die is centered within the socket, so the centre line through the CPU die is off-centre by just as much as the socket is, being 1.27mm from the centre line between the mounting holes.

That makes sense to me then. I don't know where the specs came from in that thread. With that said, I know why my latest block performs worse than my previous one. I did the offset at 3mm.
