Thanks to this project, you can upgrade our beloved HP Z440 with 120 mm front intake fan. This improves airflow to your PCIe cards and internals while also adding the option to install a dust filter, so your system gets cooler, fresher and cleaner air, as they deserve.

Filter assembly is secured using 2 magnets (3x3mm) and 2 printed clips, and the design uses the original mounting holes of the chassis - no drilling required.

Important: To install the front filter, you must cut the plastic sections marked in red in the reference photo.

Included Files:

  • Z440_120mm_front_fan.3mf — Adapter bracket that converts the original front intake opening to fit a 120 mm fan. Use M3 screws and nuts for mounting. Side pockets are included to hold the nuts in place.

  • Z440_washer.3mf — Small square washer/spacer designed for the filter assembly. Useful if your existing washers are too large. Sized specifically to fit the square mounting holes.

  • Z440_fan_filter.3mf — Front intake filter frame with integrated clips. Designed for 3 mm thick filter material (I used mesh/filter from AliExpress).

Benefits:

  • Supports quiet and efficient 120 mm fans

  • Better airflow for GPUs / PCIe devices

  • Optional front dust filtration

  • Uses original chassis holes

  • Clean OEM-like installation
