The MoDek Plans

Background Information

    The MoDek is my first CPU Cooling device. As you may have noticed it is liquid based.  Meaning it functions through the circulation of liquid within the system. This system is meant to be relatively inexpensive.  The prices of the components may vary according to where in the world you chose to build this system. In addition, nearly all of these parts can be found either new or used.  Therefore I cannot give you a definite construction price for the system.  All  I can assure is that if you obtain these parts as used or from junk yards the total cost of the system will not exceed $20 US.

Parts Needed

         Cooler:

  •   rubber tubing 2 to 3 mm. in diameter (length varies with relative position of water supply, etc...); I used about 1 m. silicon rubber aquarium tubing  total for this system, but other tubing may be used.
  •    two metallic  tubes 3 mm. in diameter and 2 to 3 cm. in length (those inserted in the water jacket)
  •    a  6.2 x 6.2 cm. x 2 mm. copper plate (less is possible but do not exceed 1 mm.)
  •    a 6.2 x 6.2 cm. x 5 mm. plastic or plexiglas plate (with a square cut in the middle for  liquid circulation)
  •    a 6.2 by 6.2 cm  x 2 mm. plastic or plexiglas cover for the thicker plate
           Electrical Devices
  • 12 V. DC windshield-wiper pump. 
  • NOTE: I used a power control in order to observe the results of the pumping rates for my scientific experiments  However,  you could also connect the pump directly to one of your computer power supply jacks pertaining you have a  250 WATT power supply (minimum).
  • A 12 V. DC power supply 
  • electrical wiring
Construction Procedure
 
  
Step 1: draw out the dimensions of your cooler in the thick plastic plate with a marker and  drill four holes leaving about a 5 mm. margin around each side. 
 
 

 

Step 2: unscrew the saw and screw it back in such a way that it is embodied within the inner square that you have formed with the four drilled holes.  Then simply saw through until you have removed the inner square (make sure you have drawn out the inner square perfectly before you begin to cut it out).

 

 
 Step 3: Once you have sawed out the inner square you should have something similar to this.
 


 
 
 
 

 

Step 4: Take the piece of thinner plastic and cut it to the the same outside dimensions as the thicker piece. Then glue both plastic pieces together.  Once the glue is dry, drill two holes diagonal from each other that go through both plastic plates (see picture).  The holes can also be drilled on any two opposite sides of the jacket, depending on your choices. Now, file a cavity in each copper tube as shown.  Once this done, you may insert the two copper tubes in their emplacements and glue them to the jacket.

 

 

 

 

 

 

 

 

 

 As you can see below, the filed tubes allow for a maximum dispersion of the liquid onto the copper plate.  Causing more efficient cooling. 

 

 

Step 5: Glue what you have to the piece of copper plate you have in your possession. In this case I had a copper plate larger than my jacket, so I had to cut around the jacket in order to make the plate even with the jacket.

 

 

 

Step 6:  Let the system dry well for at least an hour or two if you have opted for hot glue.  If you have used epoxy, let it rest a day or two before making your MoDek system operational.
