The Asus A8N-SLI NVIDIA nForce motherboard uses a heat sink and cooling fan assembly to keep the Socket 939 central processing unit cool and functioning properly. Replacing the fan on this motherboard requires a complete replacement of the cooling assembly, as most CPU cooling assemblies do not have easily detachable fan units.
Instructions
1. Turn off your computer completely by choosing "Shut Down." Remove the power cable and peripherals attached to your computer.
2. Remove the cover from your computer tower. Some cases have covers that slide right off, while others need buttons depressed or thumbscrews removed.
3. Detach the fan's power cable from the motherboard.
4. Push the latch on the side of the heat sink up to detach the heat sink and fan assembly from the retaining socket on the motherboard.
5. Unhook the cooling assembly from the retention module base on the side of the heat sink. Pull the cooling assembly out of your computer.
6. Check the bottom of the replacement cooling assembly before you put it onto the A8N-SLI CPU socket. Remove the plastic protective film covering the thermal compound. Line the cooling assembly up with the retention socket and lower it down.
7. Latch the heat sink onto the retention module base. If you latch it correctly, you'll hear it click into place. Lower the retention latch down to secure the cooling assembly. Connect the fan to the motherboard power pins. Close the case and return all cables to the back of the case.
