Cooling Door for GoPro

Introduction

Blowcase is an innovative and simple cooling solution for action cams. Here's how it works:

For the GoPro:
Cooling efficiency: - Passed a 12 hour test at 4k120fps at 80 degrees - 0.5w power consumption (less than 7% of what the camera consumes)

Cooling is achieved by a small fan on the custom door for the camera, which blows air through the inner part of the camera and blowing warm air through the power button on the side. For the device to function, the rubber button on the camera has to be removed, which means it won't be waterproof anymore.

The fan produces some noise, so it's recommended to use an external mic for good audio quality.

Works with GoPro 9-13

How to Use

Initial Setup

GoPro

• Put GoPro Labs firmware onto your camera, Scan !TUSB QRcode to allow power from USB without internal battery
• Remove rubber cover of the power button from the camera so the air flow can go all the way through the camera
  Note that this is a permanent modification and your camera won't be waterproof anymore
• Snap the cooling door instead of the original one and plug in the USB cable. Turn the switch on to enable the cooling fan
