Replace the original front plate of the valve index with two fans with adjustable fan speed.
Installing this part will void your warranty.
Model is based on the official step file provided by valve on github but I modified it quite heavily.
Both 3MF and .step are provided for this model if you'd like to make it fit any other size of fan or component
Materials needed:
| 40x10mm fan | 2 |
| USB cable (male) | 1 |
| Rotary potentiometer | 1 |
I picked up a pair of “Sunon MF40100V21000UA99” which works great. Low watts and 5v.
(standard DC fans with no PWM)
For the USB, you can buy any cheap USB cable and split it open to take the positive and negative.
The lowest resistance potentiometer I had in my workshop was a 1k, lower resistance would have been better. (Might fix it some day :D )

I would recommend printing it flat in this orientation, and with tree supports:
