Alienware X51 — Liquid Cooling

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.
