*Does not use the Valve Index's faceplate as this impedes airflow.
This is quite an interesting mod that fits snuggly into the frunk of the Valve index. There is a little push to be securely fitted into the port and a bit challenging to take out however I don't really need to remove it. Looks good, just no room to put a fancy faceplate with fan holes, maybe in a future design it can be more flush with the device. Once you flip the slider switch on the minidex the fans start up. These fans are so quite you forget it's running and forget to turn them off if you want to! I believe a little LED indicator could be useful here.
After extensive use in HLA, Boneworks and beatsaber it seems to keep the headset cooler and I can go a little longer before I am sweating. This does not blow air in you face as you play its just blowing hot air out of the headset and I think it helps. I do recommend another product in addition to this which is an O2 Cool or SLENPET Portable Waist Clip Fan (very very good) to help more direct airflow to your neck and face. With these two you can play for hours and hours imo. By itself it adds at least 1+ hours of gameplay for me. I would definitely recommend.
All good the fans are silent and generally I'm satisfied
Works great, damn near no sound
Despite it being so quiet it does indeed help quite a bit. Although I did have a little trouble getting it into place at first. Once you do though? It slides right in and is a nice tight fit (That's what she said). Also while I do enjoy the product and am glad I bought it? I do have 2 suggestions for future iterations (If there are to be any)
1. A small LED indicating power is on/off
It's quiet enough after a session in VR when I take the headset off I've completely forgotten it's on and end up leaving it on for hours till I think, "Oh wait, I should probably check to see if I turned that off or not...". Or if possible, a letter to Valve/Steam suggesting an idea so that upon shutting VR down a warning/notice will pop up indicating that you still have a device plugged into your HMD.
2. The switch to turn the fans on/off raised up to be a little taller
As it is, it's pretty flush with the rest of the device. Looking at it you can turn it on/off without any issue what-so-ever. But while in VR and if you've forgotten to turn it on or just got warm enough to warrant using the fans? It's kind of a pain to operate it with the headset ON. A raised switch would alleviate this issue.
Besides the suggestions? Love it, works well, am definitely recommending to people who play highly active games in VR.
Pleased to find that the fans work flawlessly and the snug fit in the trunk handles vigorous movement (like Beat Saber) just fine. Only problem so far is forgetting to turn them on or off because of how quiet the fans run.
