Quad Fosi Audio V3 Mono Box with Fans

Update to my dual box setup. Now all four Fosi V3 Mono  amps are housed in the same box. 

Why four amps? I use a digital crossover of my DIY speakers (CamillaDSP).

In my setup, I use two  “audiophile-grade” Noctua NF-A12x25 5V PWM fan, controlled by a Raspberry Pi to run at 50% speed only when music is playing. However, any standard 120mm x 25mm fans with speed control should work just fine. At this speed, the fan adds only ~2dB over ambient noise, inaudible from the listening position. When the fan is off, the design still allows for sufficient passive convection cooling to keep the amps operating within a safe temperature range.

Hardware Needed:

• Eight M4x30 screws (for fan)
• Two Noctua NF-A12x25 5V PWM or other 120mm x 25mm fan with speed controller.

Printing Details:

• Printed in PLA using a Bambu X1C. No supports needed.
