3. 

Installing the MCW5000-PX™ water-block 
 

Block orientation 
The MCW5000-PX can be oriented in any direction that 
suits your needs. Removing the 4 socket screws that 
attach the frame to the housing will allow you to rotate the 
frame 90

°

, so that inlet and outlet face up and down 

instead of left an right. This does not affect the 
performance of the block, nor the ability to bleed it 
properly.

 

 

 

 

 

Install the block onto the CPU, and 

gradually tighten the screws

 in a crisscross 

pattern until you feel that they reach the bottom of the standoff.   A “finger-tight” lock 
is sufficient, do not jam the screw into the standoff !  Conversely, adjustments such 
as tightening the screws only partially are 

strictly prohibited

. Such attempts will 

result in improper contact between the CPU core and the heat sink, and result in 
CPU overheating. 
 

Cooling circuit setup in dual CPU configurations: 

 
In a dual CPU configuration, simply connect the blocks in series as shown in the 
picture to the left. 

 
 

4. 

Connect the block to the rest of the cooling circuit.  

The block is designed in such a way that it will bleed itself automatically in any vertical orientation (computer standing-up). 
Recommended coolant:  distilled water+ algaecides & corrosion inhibitors are mandatory (automotive antifreeze). 
 
 

5. 

Final inspection 

Once the installation is completed, 

it is always a good idea to test the circuit for leaks, prior to powering up the computer

Troubleshooting help is available on our web site at

Note concerning removal of the tubing

: Push in collet squarely against face of fitting. A tube removal tool is provided with the 

MCW5000 block. With the collet firmly held against the face of the fitting, the tube can be safely pulled out. Do not attempt to pull the tube out 
without pushing squarely against the collet. This may result in damaging the fitting. Further details for using quick-connect fittings are also 
available here:
