LN2 pot, mounting plate

[ogblaz]

Hello! 

I bought used copper pot and it didn`t came with mounting plate. 

Before I go and make it by hand I ask if anybody got the thing drawn so I can make it cut by laser ?  Or maybe .stl for 3d print? 

The pot diameter is 71mm, I hope I will use it on 775 and 1150/55 motherboard. The more holes the better . I could use a good big backplate! 

 

Thank you all and have a good one, Blaz

Not sure how much it'll cost the have it CNC'ed, you can also buy a backplate from Kingpin for $28: https://kingpincooling.com/products/cpu-lower-mounting-plate-lga-1700-t-rex-venom-f1

 

For 3D printing, there are some STLs on Thingyverse: https://www.thingiverse.com/thing:1847908. Just keep in mind that plastics don't usually like cold temperatures and can become brittle. Intel doesn't specify exactly what the socket housing is made of but it seems to resist cold temperatures pretty well:

Quote

The housing material must be a thermoplastic or equivalent, UL 94 V-0 flame rating, temperature

rating and design capable of maintaining structural integrity following a temperature of 260 °C

for 40 seconds which is typical of a reflow/rework profile for the solder used on the socket. The

material must have a thermal coefficient of

expansion in the XY plane capable of passing

reliability tests rated for an expected high

operating temperature,

mounted on FR4-type

motherboard material. The creep properties of the

material must be such that the mechanical

integrity of the socket is maintained for the use condition outlined in Chapter

5

Checking a list of UL 94 V-0 plastics, ABS seems the most obvious choice: https://www.protolabs.com/resources/blog/flame-retardant-thermoplastics-and-ul-classifications/ .

Hey wutske, thanks for you response! 

I am good with my hands and have some tools to use so I made the plate at home.  Buddy1 from this forum send me files so I could 3d print the plate with abs. As you said I am not confident to use that with ln2 so I made the plate out of 2mm aluminium sheet (used Buddy1 3d print as a template, THANKS MAN! ).  I would like some thicker one, but that is the best I could find below my work bench it should hold just fine . 

 

Thank you all for your help and have a good one, Blaz

2mm was not enough it was bending. v2 version with 4mm thick aluminium  . Made backplate too. Enough grinding and drilling for now  .

Have a nice day, Blaz
