Make a Water Block Out of a Heatsink for Less Than $20!
Intro: Make a Water Block Out of a Heatsink for Less Than $20!
With CPUs and other computer components becoming hotter and more powerful faster and faster; traditional air cooling methods are no longer efficant enough to cool these components. Another way to cool components is water cooling, but this can be very expensive, which is why, in this Instructable you will learn how to create your own highly efficant waterblock for $20 or less! I made my waterblock to cool a 168 watt thermoelectric junction
STEP 1: Materials and Tools
-a 120V plug-in drill
-some plexiglass or lexan sheets#
-a heatsink with wide spread fins
-JB weld#
-2 brass (or plastic) screw-in barbs#
-a hacksaw
-a thin sharpie*
-a centimeter ruler (this is a MUST I'm living in the U.S.A and even I'm using one; they're more accurate)*
-a large quick-clamp
-a piece of wood with a straight edge
-a utility knife with a sharp blade*
-various drillbits*
-vinal tubing to match the barbs*
-sandpaper*
-a file*
-SOS pad*
In total all of my materials were easily accessable from Lowes and costed $13.00

NOTE: plexiglass and lexan are not the same thing, lexan is stronger and more expensive, but when I say plexiglass I mean lexan.
STEP 2: Planning Water Routes and Cutting Out Heatsnk
STEP 3: Cutting Plexiglass and Cutting Barbs
STEP 4: Polishing the Bottom
STEP 5: Dry Fit and Gluing
STEP 6: Leak Test
STEP 7: Final Thoughts
did a very good job of cooling the TEC
didn't obstruct water flow
can't beat the price! :D
I love comments, so leave one! :)
total cost: $15 :)
EDIT: 8/19/2010 ok so this thing was a flop, it broke again, except this time on the opposing side, I dont feel like fixing this every time. So I made a soda can waterblock, and haven't had anything go wrong yet :P

I think a good revision, would be to negate cutting holes in the fins. Then, seal the inside in a manner that would direct the flow of water to travel the furthest distance over the heat sink. This way you are attempting to remove heat from all parts of the heat sink fins. Remember, water is just like air, is just like electricity, path of least resistance is always preferred.
Example, move the heat sink fins to one side of the block, leaving about 2mm of space for water to flow out the end of the fins opposite of the inlet. Next, ensure that the inlet tube has a sealed wall equally separating the distance between the inlet and outlet tubes. This seal should run the length of the heat sink.
Next, position the outlet tube parallel to the inlet on the other side. Then create a seal that encloses the inlet and outlet tubes so the flow of water has to travel into the slits of the fins down to the bottom of the heat sink before traveling laterally.
I think this may help remove more heat and provide a better heat capacity to the overall design.

Great Idea
Thanks :)

This is neat and all, and I suppose 5 years ago this might have been a cheap alternative, but today you can buy a 42x42x12mm aluminum cpu waterblock for $10. A cheap motor and radiator, plus hoses and mounting tools, will set you back another $30, for a $40 full watercool system. If you've got a beefy video card, tack on $10 - $17 to cool that thing (depending on the number of GPUs), and your total sits at under $60 for a full CPU/GPU watercool setup.

I made this because I was young and unable to order things on the internet. To be 100% honest I would never reccomend watercooling to anyone, it's a novelty really.

I've been experimenting with water cooling high power LEDs, and this is a freaking awesome idea.
If you're using acrylic sheets, you should consider a solvent-based glue made for plexiglass, like they use for DIY aquariums and the like. It essentially welds the plastic together, and makes for really strong containers.
Considering the quantity of heatsinks I already have, this saves me a righteous bunch of money. Thank you!

Huh Somehow I never thought of that. I made this a while ago and I've since learned about that exact adhesive, But for some reason I never connected it to this project. Thanks for the comment I might just have to make one of these again!
