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

Long sessions with the Index can definitely start to warm up your eyeballs, so this is a fairly necessary accessory in my opinion. First thing I will say is that I wish it had been easier to install. The USB cord is understandably short, but I actually had to pull it a lot more than I was comfortable with in order to pop the fan piece in place. I can only imagine it will be equally difficult to remove, but fortunately I have no need or intention of removing it. Second note, the fan is not very loud at all. You will not hear it while playing. You will only feel the air moving if you place your hand right over it, but don't let the low power fool you. It will certainly remove the heat. I do wish there was an LED indicator to show when it's on or off. The power button is only slightly lower when it's on, so sometimes it can be difficult to tell, especially when the index is on your face. Regardless of any of my gripes, this is a must have for Index owners.

For just $32, this little mod for the Valve Index is amazing. You noticeably stay much cooler on your face (and forehead for me personally), and the lenses barely fog whatsoever, really not at all. It took me no time at all to install this radiator to the front, and I'm not sure why people are having issues. It's a simple plug-and-play procedure. USB goes in, and the radiator slots right in afterwards. At first it may seem like the cable is too short, but once you press in the far side of the radiator, the whole thing follows and snaps right into place with no issues at all. The fans do have a whine to them, but with the headset on you don't really notice it, and it doesn't interfere with the mic either which is a huge bonus. To be honest, there really are no drawbacks to this, and for the price point it is more than worth it. It works exactly as intended, and really makes a difference if you've never had one before but have played VR for a long time in the past. If one reason you stop playing VR often is because of heat and exhaustion in your head region, this will let you go on for much longer. Definitely recommended.

As someone who uses vr far more than most, I certainly put this thing through its paces, and it works pretty well for the most part. Good airflow, kept the HMD nice and cool while doing more active things, not too loud.At least, it does all of these at first.I ended up buying three units because after a few months, one of the fans started making a hideous, loud grinding noise and I couldn't make it stop. This happened on all three.

If you play VR often, this KIWI design USB radiator fan is a game changer. It cools my face, making long sessions way more comfortable, and I’ve noticed less eye irritation from the heat. Easy to install, quiet, and does exactly what it should. A must-have for Valve Index users! No complaint for the sound. It’s quiet, works great, and the build quality is noticeably good. Nothing like it in the market. 10/10

Works well, helps keep the temp down, but not so high speed that it irritates my eyes. Would be great to have a speed setting.

This device is excellent.Even for live streamers, you can hear it but only very slightly, but only if you have sensitive ears. Hearing a fan is to be expected. It is moving parts after all.This bad boy will extend your play time. And help you feel more immersed in your games because you will notice your face can actually breathe. The amount of air that is displaced out and away from your face is refreshing.Some people are saying it does not fit after plugging the USB cable in? I got it on my first try no questions asked..This is worth every penny considering it's one of a kind on how the design works.Other designs cost 4x as much and do input/output. This one efficiently outputs, and doesn't put a dent in your wallet.The button is slick and hides well, unless you know where you are pressing at times I found myself struggling to find the on/off switch while in the headset. But that is not a huge issue.Snap on / off seems to function properly with no issue. It holds to the headset and seems to perform through abusive matters because we all know how scary the real world can be while in VR.I am a satisfied consumer.

I love this Frunk Mod! It fits Absolutely PERFECTLY and has little to no gap. It's as slim as the fans can go, and pulls quite a bit of heat off the headset! However, it's not as far as Price. ($38) is quite pricey for Slapping "Index" in the title too, but so far I'm happy! The cable is plenty long, and I'm not sure if Power Consumption will be an issue since the fans run only on 2 settings. (ON/OFF) Other complaints about noise, is none. Even with my pretty decent hearing, (wearing earbuds for quite a long time) I can barely hear the MOD run! I have to take off the headset to check if it's actually running! 😆However, if your planning on taking it out or swapping mods, it WILL feel like your going to break it. Once it's in, it's kinda hard to get out. But after wiggling it around you should be able to get it out.Overall, I'd recommend if your using your Index for Long Sessions in VR. (VRChat users. BUY!) I'm also interested in other Kiwi Products and will be ordering Index Related things from them for a while!
