Removing the Processor Liquid-Cooling 
Assembly
 WARNING: Despite having a plastic shield, the processor liquid-cooling 
assembly may be very hot during normal operation. Ensure that it has had 
sufficient time to cool before you touch it.
 
CAUTION: To ensure maximum cooling for the processor, do not touch the heat 
transfer areas on the processor liquid-cooling assembly. The oils in your skin can 
reduce the heat transfer capability of the thermal grease.
1Press the tab on the CPU pump cable and disconnect the cable from the 
top lighting-board.
2Disconnect the system fan cable from the top lighting-board.
3Loosen the captive screws that secure the processor liquid-cooling
