Bushman-Tech WB - initial construction info

Initial construction infomation for below design

http://forums.procooling.com/vbb/showthread.php?t=12903




Ok finding the dimensions for the actual block is not as easy as id thought.

Having dug around procooling.com's forum and looking at various AMD socket specifications http://www.amd.com/us-en/Processors/...9_7203,00.html
ive come up with the following

whole size of cooler. according to amd pdf socket 940 specs
thermal specs cert. cooler in monunt is 77mm X 68mm @ 5 ribs = 15mm/rib ie 1 design unit = ~3mm
cam outline is 55mmx50mm @ 5 ribs = 11mm/rib ie. 1 esign unit = 2,2mm
cpu package 40mmx40mm @ 5 ribs = 8mm/rib ie. 1 design unit = 1,6mm


i was aiming for 1mm - 1,2mm design units, which means i will have enough space to increase the size depending how frustrating hand making this will be.

pin/fin height, procooling rec = 4mm , mine = ~8
base thickness, procooling rec = 1mm - 3mm



Practical Examples:

Quote:
swiftechs apogee block is 50mm x 50mm
Base plate dimensions: 2" x 2" (50.5 x 50.5 mm)
http://www.swiftnets.com/products/Apogee.asp

Materials Aquisition:
Base:
Aluminium slabs from Ebay. 135mm x 50 mm x 20 mm
http://cgi.ebay.de/ws/eBayISAPI.dll?...e=STRK:MEWA:IT

Copper eventualy, but the ease of machining Alu Vs Cu, just drives me towards
Alu for initial tests and prototypes.

Lid:
for initial tests and prototypes, aluminium.
later on some plexiglass or acrylic polymer thingy. again probably from ebay. as i dont know where to get the materials locally. but if all goes well with initial prototypes ill start asking around.

Construction plan:

print a scale side view, glue to block, start dremeling / filing / drilling.
very DIY, low budget, fun.
as i imagine it my primry tool will be
  • dremel cutting disc
  • small files
  • drill
In the design thread i have a little video attached where i kinda put the tools to the block, how i imagine i would do it. ill attach it to this thread too.
*.mp4 in a *.rar archive



convert to g-code for cnc, but thats well into phase 2, as i need to ask my dad about talking to the machinists at hiw work place. and what kind of bribe is needed for them todo some stuff for me. i hope a case of beer is adequite. lol


Questions:

Aluminium corrosion, is there any reason not to continue using the prototype blocks on less demanding system components for the semi long run?

ive been asked about budget. Well low. poor soon tobe university student low. which also translates into. ill cross the various bridges when i get to them. the initial prototypes are far more a fun hobby relaxed endevour. Thats why im willing to spend several days with a dremel working my way through a solid block of aluminium.

ps. nice little one page basic of water cooling. Something similar would be cool for the wikki http://www.directron.com/waterinfo.html

Have i missed anything? anything i should be awre of before i start my little DIY project?

I guess all i need now, is a bit of luck and some patience.
