Next steps 1. Install the heat sink. 2. Follow the procedure listed in After working inside your system on page 43. Installing the heat sink Prerequisites Never uninstall the heat sink from a processor unless you intend to replace the processor or system board. The heat sink is necessary to maintain proper thermal conditions. 1. Follow the safety guidelines listed in the Safety instructions on page 42. 2. Follow the procedure listed in the Before working inside your system on page 43. 3. If installed, remove the air shroud. 4. If installed, remove the processor dust cover. NOTE: The procedure to install standard and L-type heat sink is similar. The image shows L-type heat sink configuration system. Steps 1. If you are using an existing heat sink, remove the thermal grease on the heat sink by using a clean lint-free cloth. NOTE: For a new heat sink, the thermal paste is preapplied to the heat sink. Remove the protective cover, and install the heat sink. 2. Use the thermal grease syringe included with your processor kit to apply the grease in a thin spiral on the top of the processor. Figure 73. Applying thermal grease CAUTION: Applying too much thermal grease can result in excess grease coming in contact with and contaminating the processor socket. NOTE: The thermal grease syringe is intended for single use only. Dispose of the syringe after you use it. 3. Align the screws on the heat sink with the standoff screws on the system board. NOTE: The A1 extrusion on the L-type heat sink should face towards the system side. 92 Installing and removing system components
