Machine Maintenance Procedures

Thermal Module Installation

+ IMPORTANT:

Apply suitable thermal grease and ensure all heat pads are in place before replacing module.

! CAUTION:

Make sure thermal grease does not spill on mainboard because it may cause damage.

The following thermal grease types are approved for use:

Silmore GP50HoneywellJet Motor 7762

The following thermal pads are approved for use:

EapusXR-PE

1.Remove all traces of thermal grease from CPU using a lint-freecloth or cotton swab and Isopropyl Alcohol, Acetone, or other approved cleaning agent.

2.Apply small amount of thermal grease to center of CPU.

NOTE:NOTE:

Force used during installation of thermal module is sufficient to spread grease over CPU top.

Figure 3-34.Thermal Module Installation

3. Align module and heatsink to mainboard screw holes. (Figure 3-34)

NOTE:NOTE:

Keep module level to spread grease evenly.
