yea?  I ordered the exact screw that G put down on the plans...

OH CR@P... I got the 6-32 ones then?!  I forgot we changed it to M3?!  argh! 

What was the screw part # from McMaster?  The original spec was 1.125" which I can go under being 25mm, or over being 30mm.  I like getting longer screws, and just grind off what gets in the way. 

Here is what I found:

Standard Thread—Black
M3—Pitch: 0.5 mm
30 100 91290A130 $8.76  

Type 316 Stainless Steel—DIN
912-A4
M3—Pitch: 0.5 mm
30 25 92290A126 $9.69  

the 30mm would be better, the 30mm ends 1/16th under the stock sr2 backplate when tightened down.. I did pm you the part #, lol

Gratuitous

There were so many to search through I just ordered both anyway.

Tell you what, if you want one, I will lap it for you.  Just because ;)

  How much $$ are we talking for one? Do i have to wash dishes on this one, run some errands: like walk the dog, do laundry, wash the car, answer the Nateman_doo fan club mail?

Cheers!!  Now to get the rest of the water cooling to go with these sexy things.
 

 

 

 

 

I am cutting out the last block tonight (as I post this)
 
Looking for my safety glasses.  Can't seem to find them 

awsome, my sr-2 will be very happy.

no worries man, have a good weekend

yep, I have one.

First delrin top was cut tonight. Pics soon.

Fine work!!!!

Can do.  Send me a PM.

it was designed to allow ANY compression fitting to work, which is not the case for the original top. also I noticed no diferance in temps due to not having it centered. the flow still is directed through all the pins. when you actually get down to the physics on the issue, once the loop stabalizes in temp, it is really only pressure and surface area and flow rate that matter on the fluid flow side of things. where it could use improvement is in the actual base design. this is not the top performing block. it works as good as it originally did if not slightly better but it looks a heck of a lot better and matches the copper look. we are working on a top for the newer dd block which was tested to work as well as the top blocks from ek and others by independant testing. I didnt actually run any hydrodynamic solid works analisis because this is not really meant for mass production. I would bet that when I pulled it slightly off center, it decreased the dead spot and actually increased flow through the surface area. when and if I design an entire base block I would certainly do all of that, but at this point why re-invent the wheel.
 
I designed this top to use bases I already had in posession and use them on my sr-2 for folding 24/7 with my x5672 chips. what makes the most differance in temps is having enough flow rate and enough radiator to cool the water. it has no problem pulling the heat from the chip to water. if a 3-4 degree diferance is important to you then the new design we are working on with the new basses will do that. but you have to pull the heat from the water properly by having enough rad to do that with any block.

this is not my testing and I cant tell you that this is what happens with this block top but watch this

you can see what happens when the flow is centered like the original top. i think having it offset reduces the deadspot. but it really doesnt matter what I think, it does the job and compressions fit:) if I get some time I will model it for you.
 
really as long as water can't stagnate in the hot center area then you are good. I can't see how water would stagnent there unless you had really low flow.

yah, thanks for the visual. what you suggest might make a real minor differance. tbh though I am done with this top and moving my design ideas to a newer base with more potencial for heat removal.

this top/base worked fine but i think the new system I am working on will work better especialy as we go to 8 and 10 core xeons later this year.
this top was designed to allow compressions to fit and visual improvemnets. as long as it worked thrermaly as good as the old top, which it does I was happy with it.
 
nate may want to experiment a little idk, but for me its not worth the time on the old base when I have a new one to design for.
 
 
oh, and btw the whole reason I added the extrusion to the inside of the top was to allow for jet plates to experiment with. I didnt ever have the time to make any though and based on the performance I didnt feel the need to.

I admit that I have not read through this thread -- so maybe it was already answered.  Why is the input fitting not centered over the impingement pins like the original design used?

btw, its 3 pages - not like 300 of the G.I.C thread...
