KIWI design USB Radiator Fans Accessories Compatible with Valve Index, Cooling Heat for VR Headset in The VR Game and Extends The Life of Valve Index

Easy to fit, good quality. it slots right in and keeps the face a little cooler, great for me as I used to get quite a sweaty face from using vr.

So I was a little sceptical about just how efficient this would be, but you really CAN feel the hot air being pulled out and exhausted from your face, it's night and day, honestly I don't think I would be able to last in my Index very long if not for this exhausting some of that hot air out the front, it also seems to stop the lenses from steaming up during intense play sessions.Overall it just works brilliantly, my ONLY gripe with it is the price, sure it works but I feel like for 2 tiny fans in a plastic shroud nearly £40 is just asking too much money, I bet it only costs a few quid to make if that. But it does work, so it's a bit of a toss up.Overall thoughts? If you own an Index and are familiar with how much heat it can generate, I don't think you'll be disappointed, just remember though, it's not pulling cold air IN it's just simply moving the hot air OUT. Don't think this is some sort of air conditioning like i've seen people complain about in other reviews and on the internet.

Sooooo basically the price is a bit much but it works, easy to install as long as you do it the correct way around and it does pull alot of the heat away from your face but if you wear contacts like me don't have it on for too long, it can make your contacts dry up a bit faster than normal, the noise is defiantly notisable and it ramps up and down depending of your looking down or up. Overall its quite good for hot games like beat saber or bas but I games like vrchat I just occasionally turn it on so it pulls the heat out. I would reccomend if you're okay with all those problems

The packaging is small and efficient yet a very high quality, the instructions are small and concise. Plug in the USB and the fan has a sturdy and satisfying click when it is inserted in to place, I have immediate faith that it will stay in place and it looks sleek and fits in seamlessly with the Index headset. Out of the headset the fan whir is noticeable but not annoying or intrusive, once in VR the noise is lost under the quietist of ambient game sound.The affects are felt right away, initially it is the feeling of cool air being sucked in through the nose gap in the headset and circulating around the face and eyes, at first I felt my face was almost too cold. After some time you can hover your hand over the front fans and feel the warm air being pulled away from you. At this point my face was no warmer than the rest of my body and there was no sign of sweat or lens fog and by the end of my hour long play session that was still the case.I debated purchasing this for a while as I felt it was overpriced but now I can see that I have significantly improved the comfort of all future VR sessions. If your face gets hot and sweaty in VR and you can afford the slightly pricey upgrade, I definitely recommend it!

A fan system that not only draws air from the headset itself, but also cools the face. In order for the air to be sucked in and cool the face, leave a gap for the nose. If you cover your entire face and leave no small gap, it will not cool your face, it will only draw air from the headset itself. Cooling is done in a very gentle and pleasant way. The downside is that you can hear a little bit of a fan noise when it's quiet.

very overpriced considering its a fan with a PWM adapter, fits good though, made of plastic so durability is lacking, along with quality. compatible with my index.

No longer do I have a to stop playing beat saber or powerbeatsVR to wipe away the sweat lol, like the description says, it looks very much part of the headset to the untrained eye, just remember to turn it on!, this unit is not as quiet as the one from Kyflo or as slimline also because of the thickness of the device I cannot use my custom vented faceplate, also the kiwi device only has one speed setting where as the kyflo device has several and also an auto mode. That said the kiwi device does work very well and is the cheaper option, noise wise, both devices make a slight whine when running at max but the kyflo is a little more quieter and less noticeable. while gaming i found it unnoticeable over the ambient sounds of the room/outside but the effects definitely are.

I would go as far too say that with this I get less sweat than my quest 2! A lot of people don't go for this due too the "fan noise" but I can deter those worries.. As you only ever hear it when there's no sound happening in the index... And another important thing I didn't see when looking at reviews... The mic of the index does not pick up this light hum of the fan or at least not noticeable enough for anyone too hear it :) this is an awesome product and looks really cool and honestly I kinda like the white noise between loading screens
