Ask about this design

Our tested 2×40 mm configuration reduced GPU temperature by 1.5°C. GPU fan noise also decreased in our test (not measured in dB). 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

Two fans sit side by side to direct airflow beneath the graphics card. The mount creates a dedicated attachment point where the case may not provide one.

Featured in our PCIe fan test

I Dropped My GPU Temps for Just $0.46. (PCIe Fans 3D Printed Mod)The video shows this mount in a real PC. Tested with two 40 mm fans: GPU temperature 1.5°C lower, with less GPU fan noise (not measured in dB).

Before you order

  • Fan configuration: 2 × 40 mm. Fans are not included.
  • Requires 2 free expansion-slot positions.
  • Check case profile against the listing.
  • 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 mount with its two 40 mm fans, a red arrow out through the rear grille for exhaust and a blue arrow into the case for intake.
    Step 1

    Choose intake or exhaust

    Decide which way the fans will blow: exhaust pushes warm air out through the rear grille, intake draws cool air in toward the graphics card above.

  2. The 40 mm fans lowering into the box from the open side.
    Step 2

    Seat the fans

    Place the 40 mm fans into the box with the frame arrow pointing the way you chose. Fans are not included.

  3. The outside of the bracket with four screws going into the fan corner holes.
    Step 3

    Screw them in from the grille side

    From the grille side, fix each fan through the four corner holes with the screws (or rubber mounts) that came with the fan. No screws are included.

  4. Fan cable leaving the box through a side pass-through, with the cable clip snapping on underneath.
    Step 4

    Route the cables

    Lead each fan cable out through a side pass-through so it stays clear of the blades. Snap the cable clip back on underneath to hide them.

  5. 2 slot covers coming out of the case below the graphics card.
    Step 5

    Remove the slot covers

    Shut down and unplug the PC. Remove the case screws and the 2 slot covers below the graphics card. Keep the screws.

  6. The fan mount moving into the free slots below the graphics card, with the case screws ready.
    Step 6

    Fit it like a card

    Slide the mount into the free slots the same way as an expansion card and secure it with the case screws you removed.

  7. The installed mount below the graphics card, with the fan highlighted for a final check.
    Step 7

    Connect and check

    Connect each fan to a fan header following its manufacturer’s instructions, check the blades turn freely and nothing touches the graphics card, 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.
