Introduction

This is a simple guide to disassembling a Marsback Zephyr Pro mouse to replace the fan, with some tips on selecting a replacement fan and how to avoid breaking the mouse during disassembly.

Fan Selection

  • The fan in the Marsback Zephyr Pro is a 5v 30x30mm fan with 8mm thickness - so for this replacement you will need one matching those dimensions. A 10mm thick fan is too tall and will prevent the mouse shell from being closed.
  • You will also need to make sure that the replacement fan has the same connector, a 1.25mm Molex PicoBlade or JST Female connector - alternatively, you can snip off the old connector and solder it onto the new fan.
  • The original fan has holes about 3.3mm in diameter to fit onto the mounting posts inside the mouse. Additionally, the holes on the 'blow'/'outlet'/top side of the fan are larger at around 4.7mm in diameter to accommodate the head of a screw. This larger diameter extends about 3mm deep through the total 8mm depth of the fan. Finding a fan with these matching features isn't strictly necessary, and a fan that has simple holes ~3.3-3.4mm all the way through should work fine - just note that the screw head may get slightly stuck and the fan may simply be held by friction onto the posts.

    • Start by removing the 2 screws on the bottom of the mouse.

    • You can either remove the rear skate and re-adhere it afterwards or use a 9/64" or 3.5mm drill bit to reveal the holes

    • If you opt to drill a hole through the skate, pressing hard in the area will reveal a indentation where the hole lies

    • First, pull the bottom of the shell slightly apart to create clearance

    • Next, wiggle the bottom of the mouse's base left and right while pulling down

    • Once the locking pieces at the top are free, the base of the mouse will be detached from the top shell

    • Do not fully remove the halves until the ribbon cable between them has been disconnected

    • Open the top shell to the right.

    • Optionally disconnect the ribbon cable to give extra working space by pulling up on the ribbon cable connector's locking piece until the ribbon cable can freely slide out.

    • Unscrew the 2 screws holding in the fan and pull the fan connector out. There is no locking mechanism on the fan connector.

    • If the new fan doesn't have the correct DC connector, you may want to salvage the original fan's connector and solder it onto the new fan. If soldering on a connector, ensure the positive (red) side from the fan ends up on the left when the connector is plugged into the mouse.

    • Slide the new fan onto the mounting posts and replace the screws.

    • Reconnect the fan connector. Ensure the positive side (red) of the fan cable is on the left.

    • Reconnect the top shell ribbon cable and press down the locking tab fully before reassembling the mouse.

    • Before reassembling the shell, it may be a good idea to plug in the mouse to ensure the new fan spins and blows in the correct direction (upwards). Testing the DPI adjustment button and color changing scroll wheel will also test that the ribbon cable has been correctly reinstalled.

    • Pulling up gently on the cable can help slide the locking pieces unto place. Pay attention to the seam between the top/bottom shells.

    • Once the seam is flush, the shells are aligned and can be reattached with the screws under the rear skate.

Conclusion

To reassemble your device, follow these instructions in reverse order.
