120 mm PCIe Fan Mount

In stock

Position a 120 mm fan near your graphics card to direct airflow where it is needed. Uses one expansion-slot mounting position. Fans are not included.

Best suited to tighter cases with limited existing airflow. Results vary by case, hardware, fans and test conditions; temperature and noise improvements are not guaranteed. Check fan thickness and clearance around the GPU. Preview airflow is illustrative.

Manufactured from premium PETG-HF for thermal resistance and structural durability.

Why it’s designed this way

The design puts a dedicated fan near the space beneath the graphics card, where a case may not provide a convenient mounting point. The different sizes address different available spaces; larger does not automatically mean better cooling.

Before you order

  • Fan configuration: 1 × 120 mm. Fans are not included.
  • Requires 1 free expansion-slot mounting position.
  • One mounting position does not mean the whole fan fits within one slot of space.
  • Measure fan thickness and the full assembly clearance beneath the GPU and around nearby cards/cables. Compare with the listing dimensions.

Setup & use

  1. The 120 mm mount and fan with arrows for both airflow directions.
    Step 1

    Choose the airflow direction

    Decide whether the fan should blow toward the graphics card above it or pull air away from it. Most people exhaust warm air from behind the card.

  2. The fan lowering onto the frame with four screws below the corner holes.
    Step 2

    Attach the fan

    Lay a 120 × 120 × 25 mm fan on the frame and fix it through the four corner holes with the screws that came with the fan. Screws are not included.

  3. Arrow along the frame showing the fan cable route.
    Step 3

    Route the cable

    Run the fan cable along the frame’s built-in channels so it stays out of the blades.

  4. A single slot cover coming out below the graphics card.
    Step 4

    Remove one slot cover

    Shut down and unplug the PC. Remove one slot cover below the graphics card and keep its thumbscrew.

  5. The mount moving into the free slot, with the thumbscrew at its tab.
    Step 5

    Fit it in the slot

    Slide the bracket into the free slot like an expansion card and secure it with the case thumbscrew. No tools needed.

  6. The installed mount below the card with the fan highlighted.
    Step 6

    Connect and check

    Connect the fan to a fan header or hub, check it clears the graphics card and turns freely, then power on.

Care & troubleshooting

Wipe with a soft, slightly damp cloth, then dry. Avoid solvents and hot-water cleaning. If you notice vibration or contact, power down and recheck mounting and cable routing.
