Review on 🔥 Boost Valve Index VR Headset's Lifespan with KIWI Design USB Radiator Fans - Optimize VR Game Cooling and Heat Dissipation by Mike Johnston

This product cools the electronics of the headset very well. The exhaust air comes out cool even after several hours of play. In my opinion the product could have been a bit quieter, with reduced airflow, and it would still have cooled the headset adequately. How well it actually protects the front from fogging up or anything like that, I can't say. I've never had problems with sweating. I /think/ it's a bit cooler, but I'm pretty sure I can't feel the airflow with the fan on. This is probably mostly due to the design of the headset (very limited travel to the front of the headset). Also, I can't say for sure that I want the area to have a lot of airflow that might dry out the eyes. After all, I find it a little overpriced for what it is, a pair of low-voltage, switch-type fans, USB powered. In my opinion a speed control, even just low/high, would definitely justify the price.
