Custom motherbaord waterblock

post #1 of 8
Thread Starter 
So ive been thinking of watercooling the VRM (or whatever the 2 heatsinks around the cpu area cover) on my P7P55D-PRO because with my overclock, those heat sinks get really hot. I mean uncomfortably hot. So simple solution, put them under water. Only problem is i cant find a block for my motherboard. But that's okay, ive always wanted to make one anyway!

I know it will be expensive, and probably not turn out right the first time, and im better off buying some universal blocks or something, but hey i want to try to make them myself because i think its fun. Im not here to ask you if its worth it, its worth it to me smile.gif

I do not have access to a CNC or a mill of nay kind for that matter, but i have access to some pretty good hand tools and im decently crafty. So here is the plan:

-Get a 0.5" x 0.25" x12" (W, H, L) square copper rod. I can pick this up locally for less than $10
-Cut the rod down into 2 pieces each half an inch LESS than the length of the two waterblocks (two blocks to replace 2 heatsinks)
-use the remaining copper to make 0.25" plugs to braze or weld to the ends of those blocks to make them full length of the heatsink. (the brazing will happen later)
heres the interesting part:
-take my 0.25mm jewelers hand saw (and yes it can cut copper just fine i believe) and methodically carve teeny tiny channels into the blocks. Much like todays CPU waterblocks
-while making those channels leave enough room on either end to place an O ring or something for sealing it later.
-now that the blocks have channels, braze the two "end caps" i cut earlier onto either end so as to seal the channels in the rod. otherwise water would just spill out as the channels are straight through
-drill and tap 4 holes at each corner for mounting the acrylic top cover
-polish the bananas out of it and sent it to get nickel plated (maybe)
-cut appropriate size acrylic tops, and drill holes in them for the fittings to screw into. also tap those holes for the fittings. also have extra overhang material with mounting holes into the motherbaord. plan is to sue nylon screws to attach it later)
-screw the top down onto the block with an O ring or some other sealant.
-pressure test with my compressor (how much PSI would you say is good?)
-install in motherboard.

I may potentially want to merge the two blocks into one solid piece making a 90 degree bend. (or connect them together by brazing a copper pipe between them)

So my only real question is, will this kind of "tiny channel" design be too restrictive for the loop? Will my pump struggle with it? its a ddc 3.25 and ive read that it likes more head pressure.
Also would this actually provide any sort of cooling benefit over the stock heatsinks?

And most importantly, what do you guys think of the plan? any input is appreciated!

Any description that has to use the word "methodical" sounds a little sketchy to me biggrin.gif

However, I don't think the channels need to be super tiny either. If you look at most RAM blocks, they have pretty large channels, the VRMs don't need super precise channels.

I'm not sure I really understand what you are doing with the copper rods, but it seems much simpler to me if you get someone to CNC a copper block to the shape you want. You'll have a much higher quality result that way.

I can understand you wanting to create something, I am the same way. As stated above, I wouldn't bother with creating chanels as it prob won't make much of a difference. MIPS blocks, do not have cancels, and work very well.
Not sure if you have looked at the watercool SW blocks? They might be a good starting point for this project, and you could cut them to size as needed.
I do believe you could make a block, via hand tools, and brazing, and it may be a fun and good learning project.
I have seen a few tutorials on making blocks by hand, I don't have any links to share, as they were older, but I'm sure still posted somewhere.
Good luck, and take pics

+1 on the taking pics. It'd be nice to have some reference on your experiences.

I will definitely take pics smile.gif

I requested a pair of quotes for a 0.25 X 0.5 bar and a 0.25 x 0.75 bar. Im afraid the 0.5" will be a tad too small as thats actually narrower than the stock heatsink. 0.75 however is far too wide. something like 0.625 would be just perfect but the place i turned to doesnt have that as an option so, should i chance it with the 0.5" or just get the 0.75" and cut it down to desired size?

The channels are not so much for performance, i know they wont make a difference, i want channels rather because they're easy to make with a hand saw and i don't have power tools. other than a drill and a dremel.

EK still have some blocks available for that motherboard.

At least the pics will give you an idea what to aim for if you're making your own.

I looked at the EK blocks, koolance, and watercool ones. I am having some difficulty finding a copper block however i did find copper sheets so it made me rethink my idea a little bit

what if i take a sheet, cut it to size, and solder copper nails to it to make fins pins. So it literally looks like a heatsink. then take some plexiglass and top the block with it so that its still possible to dissemble if need be. I am a little concerned about the plexi top not making a watertight seal, so an alternative would be to solder copper sides and top out of the same copper sheet. Do you think that would be better than a plexi top?

Also if its soldered, would that affect temperatures negatively? more importantly, would that cause any problems in the loop with corrosion? is the solder itself safe for water to come in contact with?

What about the block from an aquero? Or the little tiny blocks for graphics cards I think they are called mcr-one, made by aquacomputer a few years back, specialtech has/had them in stock.
