Removing the processor cooling-assembly WARNING: Before working inside your computer, read the safety information that shipped with your computer and follow the steps in Before working inside your computer. After working inside your computer, follow the instructions in After working inside your computer. For more safety best practices, see the Regulatory Compliance home page at www.dell.com/regulatory_compliance. Prerequisites NOTE: You will hear a low bubbling sound when the computer is turned on. The sound is standard for all computers with liquid cooling units and stops after a few minutes of computer use. The bubbling sound is due to the air that resides in the liquid cooling assembly. When the temperature of the liquid rises, it expands and the air bubbles in the tube are dislodged. Alienware X51 being a compact desktop computer, initially the sound may be more audible as compared to the liquid cooling units in other larger desktops. The liquid cooling unit dissipates these sounds after few minutes of use. Remove the side panel. Procedure 1 Remove the fan cable and processor-cooler cable from the routing guide on the chassis. 2 Disconnect the fan cable and processor-cooler cable from the system board. 3 Remove the screws that secure fan to the processor cooling assembly. 14
