XPS 8950 Service Manual
Removing the processor fan and heat-sink assembly (125 W, water cooling)
Prerequisites
- Follow the procedure in Before working inside your computer.
- Remove the left-side cover.
About this task
NOTE:The heat sink may become hot during normal operation. Allow sufficient time for the heat sink to cool before you touch it.
NOTE:For maximum cooling of the processor, do not touch the heat transfer areas on the heat sink. The oils in your skin can reduce the heat transfer capability of the thermal grease.
NOTE:The processor fan and heat-sink assembly (125 W, water cooling) consists of one radiator fan and one heat sink that is linked by tubing containing water. Ensure that you do not damage the tubing when removing the processor fan and heat-sink assembly. If there is a leak, replace the processor fan and heat-sink assembly.
NOTE:This procedure only applies for computers shipped with a 125 W processor.
The following image(s) indicate the location of the processor fan and heat-sink assembly (125 W, water cooling) and provides a visual representation of the removal procedure.
Steps
- Place the computer on its side with the left side facing up.
- Disconnect the radiator-fan cable from the system board.
- Disconnect the processor-fan pump cable from the system board.
- In sequential order (1>2>3>4), loosen the four captive screws that secure the heat sink to the system board.
- Remove the screw (M3x5) that secures the radiator fan to the chassis.
- Slide the radiator fan off the alignment posts and lift the radiator fan from the chassis.
- Lift the processor fan and heat-sink assembly from the system board.
