I have a few games in my VR backlog, and I would love to be playing them right now, but it's the middle of summer, and the VR headset makes my eyeballs sweat. I have an Index, and apparently a good solution is to have an exhaust fan plugged into the front USB, but I haven't seen a way to mount a fan to my headset without needing to 3D print a replacement front cover for the entire device. Is there a decent way of getting a front exhaust fan set up, maybe one that just fits in the small opening in the Index out of the box? Or perhaps a better solution to prevent my eyeballs from sweating from playing playing VR games?
