8. Attach the two antennas by aligning the circular fittings and pressing onto the wireless card. The connectors will snap into place. Use caution when attaching the connectors; the pins can bend, break, or snap.

Replacing the cooling system:

The Adder WS 4 has a single heatsink assembly with two fans. This assembly cools the CPU and GPU.

If the fans become noisy and cleaning them out doesn't fix the issue, you may need a new fan. Contact support to start a warranty claim or parts purchase.

Depending on your climate and the age of the machine, it may be necessary to apply new thermal paste between the CPU/GPU and the heatsink. Thermal paste helps facilitate effective heat transfer between the CPU/GPU and the cooling equipment. These instructions can also be used in the unlikely event your heatsink needs to be replaced.

Part numbers:

• The fan/heatsink assembly's manufacturer and part number is Yingfan 6-31-V350N-201.
• The left fan (with stamped numbers 1/2/3) is a WINMA EGC-85071S1-0AH.
• The right fan (with stamped numbers 4/5/6) is a WINMA ECG-79731S1-0AH.

Tools required: Cross-head (Phillips) screwdriver
Time estimate: 25 minutes
Difficulty: High ●

Steps to replace the heatsink/thermal paste:

1. Follow the steps above to remove the bottom cover and remove the SSD from slot 3 (if installed).
2. Remove any clear tape that is securing the fan wires.
3. Remove the thirteen heatsink and fan screws in order of the stamped numbers, starting with #1, then #2, and continuing until you have removed #13.
   • The black screws (#1-#12) are held captive, and will not completely detatch from the heatsink/fans. The silver screw (#13) is not held captive, and will come loose when untightened.
   • Do not remove the smaller black screws holding the fan covers onto the fans.

4. Unplug the two black fan connectors from the motherboard (highlighted green above).
5. Remove the heatsink/fans from the case, being careful not to bend the heatsink pipes. It may take some pressure to break the seal of the thermal paste.
6. Using a paper towel, remove the existing thermal paste from the CPU, GPU, VRAM chips, and heatsink. You may also use a small amount of rubbing alcohol if the old paste is dried or difficult to remove.

7. Apply a small line of thermal paste directly onto the CPU chip, GPU chip, and VRAM chips.

8. Carefully replace the heatsink.
9. Replace the fan and heatsink screws, starting with #1, then #2, and so on until #13.
10. Plug the two white fan connectors back into the motherboard.

Replacing the keyboard:

The keyboard can be replaced if its switches or electronics have been damaged.

Warning: The keyboard is held in by a strip of adhesive in addition to one of the bottom panel screws and the perimeter clips. The adhesive may be difficult to remove from the keyboard and/or case, and while the keyboard should still be functional if removed carefully, it is possible that permanent aesthetic damage will occur to the bottom side of the keyboard during removal. Removal is not recommended unless the keyboard is malfunctioning.

Part numbers:

• The keyboard's part number is 6-V355SNC-KB-MCL-US.
  • Keyboards shipped by System76 include a custom-printed Super key.
