60mm Muffin Fan Diffuser
thingiverse
A recently purchased Anet A8 Plus has a rather noisy muffin fan for cooling the power supply and is not cycled thermostatically so the noise is constant while the machine is running. Additionally, there's way more airflow than is needed to keep the power supply cool while under operating conditions. This diffuser brings the noise level down from approximately 52dB to 45dB on my unit. Yours may differ. Mount using double sided tape. Drilling holes in your power supply is not recommended.
