Practical - 81 :- Installation of a Microprocessor (CPU), Heat Sink (Cooling Fan), and the Motherboard into a system cabinet.

 

AIM :- Installation of a Microprocessor (CPU), Heat Sink (Cooling Fan), and the Motherboard into a system cabinet.

Tools Required

• Phillips Head Screwdriver (Magnetic tip preferred)

• Thermal Paste (If not pre-applied)

• Anti-static Wrist Strap (Optional, or touch a grounded metal object)

Step 1: Install the CPU (Processor)

1. Open the Socket: On the motherboard, push the small metal lever down and away from the socket to release it. Lift the load plate.

2. Align the CPU: Look for a small golden triangle on one corner of the CPU. Match it with the triangle marked on the motherboard socket.

3. Seat the CPU: Gently place the CPU into the socket. Do not press down. It should drop in naturally.

4. Lock it: Lower the load plate and press the lever back down into its locking position.

Step 2: Apply Thermal Paste

• Check the Fan: If you are using a new "stock" cooler, it likely has grey paste already on the bottom. If so, skip this step.

• Application: Place a pea-sized drop of thermal paste exactly in the center of the CPU lid. Do not spread it; the pressure of the fan will do this automatically.

Step 3: Install the CPU Fan (Heatsink)

1. Positioning: Place the fan on top of the CPU, aligning the four mounting pins/screws with the holes in the motherboard.

2. Secure the Fan: * Intel (Push-pins): Press down on opposite corners (diagonal) until you hear a click.

   • AMD (Screws/Clips): Tighten the screws in a "cross" pattern to ensure even pressure.

3. Connect Power: Plug the fan’s power cable into the header labeled CPU_FAN on the motherboard.

Step 4: Mount the Motherboard in the Case

1. I/O Shield: Snap the rectangular metal plate (I/O shield) into the back slot of the computer case.

2. Standoffs: Ensure the brass "standoffs" (spacers) are screwed into the case in positions that match your motherboard's holes.

3. Placement: Gently slide the motherboard into the case so the rear ports fit through the I/O shield.

4. Screwing: Use the motherboard screws to secure the board to the standoffs. Do not over-tighten, as this can crack the circuit board.

Important Safety Tips

• Handle by Edges: Always hold the motherboard and CPU by the edges to avoid touching the sensitive gold pins or circuits.

• Static Discharge: Before touching components, touch a metal part of the computer case to discharge any static electricity from your body.

• Zero Force: If a component (like the CPU) doesn't fit, do not force it. Re-check the alignment.
