Central Processing Unit chips have a tendency to overheat when used for long periods of time. This is why virtually all desktop processors come installed with cooling systems that include a cooling fan. However, cooling fans are not invincible. They can burn out if they are not cleaned often and properly. To clean the fan in a Compaq Presario 5320 desktop, there is some light disassembling involved to gain access to your computer's CPU fan.

Turn off your Presario 5320 desktop and disconnect the power cord from its socket. Wait 10 to 15 minutes before you begin disassembling your computer.
Attach an electrostatic discharge wrist strap to your wrist and attach the wire clip to the outer casing of the desktop.This helps prevent damage to your computer caused by static electricity.
Rotate the desktop so the back panel is facing you. Place the desktop on its left side. Remove the two Phillips-head thumb screws from the right side of the computer's back panel. Grasp the moulded grip on the side access panel and slide the panel away from the desktop. This will reveal the interior components of your computer.
Locate the cooling fan assembly attached to the back panel of your computer. Grasp the power cable extending from the fan, follow the cable to its connector on the motherboard and disconnect it from the motherboard. Locate the locking tabs on either side of the air duct assembly. Insert a small flathead screwdriver into the notches on each tab and disengage each tab. Remove the air duct once the air duct assembly comes loose.
Repeat this procedure in reverse to install the new cooling fan assembly.
