Processor Heat Sink Note: Server configurations with a single processor have a regular heat sink and a blank heat sink installed.
1. Loosen the four screws securing the heat sink in the order indicated below.
Caution: Whenever you handle the heat sink, handle it from the slotted sides, not the smooth sides. Grasping the smooth sides of the heat sink can compress its ribs causing permanent damage.
2. Caution: Each heat sink is connected to the logic board by a small 2-pin thermal sensor cable. Lifting the heat sink too quickly can damage the cable or connector. Because of the tight thermal bond between the processor and heat sink, be especially cautious to initially lift the heat sink no more than one centimeter (1 cm) off the processor. Do not pull on the cable as you lift the heat sink enough to disconnect the cable from the logic board.
Installing the Replacement Processor Heat Sink Note: The thermal bond between the processor heat sink and the processor requires thermal grease for proper operation. Every time you remove or replace the processor heat sink, you must replace the thermal grease on the processor below the heat sink. New grease and an alcohol wipe for cleaning off the old grease are included with the replacement heat sink. Clean the processor and apply new grease as follows 1.
4. Clean off any existing thermal grease on the top face of the processor using the alcohol wipe provided with the replacement part, being careful not to get any thermal grease on the processor contacts. 5. Apply the entire contents on a single syringe of thermal grease (approximately 4.5 cc) to the top surface of the processor. Important: Be sure not to get any grease anywhere on the processor other than the very top, flat surface that directly contacts the heat sink.
6. Use the edge of the package that the alcohol wipe came in as a spatula to spread the thermal grease evenly over the entire top surface of the processor. Scrape off any excess grease with the package edge, then discard the package. 7. Holding the processor by three corners only, keep the processor level as you place it into its holder on the logic board, being careful not to get any thermal grease on the contacts of either the processor or its socket holder.
Note: When installing the processor on the logic board, align the processor notch with the tab on the processor holder, as shown. Then lower the processor straight down onto the socket. 8.
