Installing CPU and Heat sink (TS4-1686449 / TS4-187485002 / TS4-1910483)

3-part installation

Instructions to remove the top chassis cover can be found here: Removing the Chassis Cover (TS4-1686449 / TS4-187485002 / TS4-1910483)

Part 1 - Processor Carrier Assembly

  1. Hold the processor with the LGA lands (gold contacts) facing up. Locate the small, gold triangle in the corner of the processor and the corresponding hollowed triangle on the processor carrier. These triangles indicate pin 1. See the images below.

  2. Using the triangles as a guide, carefully align and place Point A of the processor into Point A of the carrier. Then gently flex the other side of the carrier for the processor to fit into Point B.

  3. Examine all corners to ensure that the processor is firmly attached to the carrier.

Part 2 - Processor Carrier and Heatsink

  1. Note the label on top of the heatsink, which marks the heatsink mounting holes as 1, 2, 3, and 4. If this is a new heatsink, the thermal grease has been pre-applied on the underside. Otherwise, apply the proper amount of thermal grease.

  2. Turn the heatsink over with the thermal grease facing up. Hold the processor carrier assembly so the processor's gold contacts are facing up, then align the triangle on the assembly with hole 1 of the heatsink. Press the processor carrier assembly down. The plastic clips of the assembly will lock outside of holes 1 and 2, while the remaining clips will snap into their corresponding holes.

  3. Examine all corners to ensure that the plastic clips on the processor carrier assembly are firmly attached to the heatsink.

Part 3 - Processor Heatsink installation into CPU socket

  1. Once you have assembled the processor heatsink module (PHM) by following the instructions, you are ready to install the processor heatsink module (PHM) into the CPU socket on the motherboard. To install the PHM into the CPU socket, follow the instructions below.

  2. Locate the triangle (pin 1) on the CPU socket, and locate the triangle (pin 1) at the corner of the PHM that is closest to "1." (If you have difficulty locating pin 1 of the PHM, turn the PHM upside down. With the LGA-lands side facing up, you will note the hollow triangle located next to a screw at the corner. Turn the PHM right side up, and you will see a triangle marked on the processor clip at the same corner of hollow triangle.)

  3. Carefully align pin 1 (the triangle) on the the PHM against pin 1 (the triangle) on the CPU socket.

  4. Once they are properly aligned, insert the two diagonal oval holes on the heatsink into the guiding posts.

  5. Using a T30 Torx-bit screwdriver, install four screws into the mounting holes on the socket to securely attach the PHM onto the motherboard starting with the screw marked "1" (in the sequence of 1, 2, 3, and 4).

Note: Do not use excessive force when tightening the screws to avoid damaging the LGA-lands and the processor.

Removal

Make sure system is powered off and power drained.

  1. Using a T30 Torx-bit screwdriver, turn the screws on the PHM counterclockwise to loosen them from the socket, starting with screw marked #4 (in the sequence of 4, 3, 2, 1).

  2. After all four screws are removed, wiggle the PHM gently and pull it up to remove it from the socket.

Note: To properly remove the processor heatsink module, be sure to loosen and remove the screws on the PHM in the sequence of 4, 3, 2, 1 as shown below.
