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

There's not much you can make use of in the Index's frunk, but this is definitely useful. Its a little noisy when everything's quiet, but if you're playing at normal volume it'll get drowned out easily. It costs about the same as building your own and printing your own housing, but without the hassle of assembly or soldering, so overall worth the cost. I'm in VR a ton and it hasn't failed me yet, that's a testament to its quality and durability. The one downside to it is that the fans are spinning so fast that they act as a gyroscope, so when you turn your head too fast you can hear the blades struggling as they reorient. Otherwise perfect use of the frunk for a bit of extra cooling.

It does actually work... I've playing with it off and i've played with it on... It does indeed make a difference.. A slight one, but still one all the same - if it's a noticeable difference then it must be significant. You won't notice it so much if you're playing something like Blade & Sorcery, where you're exerting a lot of physical energy and sweating a lot, but you will notice it if you're just hanging around in VRChat or something chill... You gotta think about it like this - It's a giant mini computer with no fans hanging on the front of your face... Those 2 added fans do quite a bit to keep you cooler... It fits near perfect. I've never had any issues with it rattling, being loose, or falling out. It's decent quality. There is a slight hum that you can notice while it's on (I wear surround-sound headphones so mine might be more muffled than yours with the built-in speakers) but it just sounds like a distant AC unit sound running in the background of the game - it isnt really that disruptive, unless youre trying to hear a pin drop, or soft footsteps.

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.

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.

This goes where that awkward plastic plate is on your index. (Don't have that thing on, I know it looks 'cool' but it burns out your headset faster!) This one device easily snaps in and connects to your index. Blowing two micro fans on the processor directly to keep it cool. This ALSO helps keep sweat buildup in your lens from happening. You will feel the breeze on your eyes and the difference is SUPER noticeable when it's not on.

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.

I used to have a dual USB fan that i had to duct tape to the 2 front openings of the index to keep the headset cool. had it on for about a year and it was really tedious to tape everything back on and clean the dust off. i would always accidentally hurt my fingers from the fans when i tried to position my headset. also the fans were audible through the mic, i had friends complain to me about how loud my fans were because they were on the headset. But with this KIWI USB fan, its compact, quiet, it does a pretty darn good job to cool off the headset from getting too hot. Im honestly a huge FAN of this Valve index fan that easily clips on your headet. it is a little bit pricey, but its sooooo worth it when youd rather risk getting your headset over heated, or having your headset with little to no heat for hours and hours of VR gaming. i play alot of beatsaber, so this does a pretty good heckin job. the sweating part is still an issue tho. so no matter what physically active game you play, this fan wont help that. but it will help dissipate the heat from the headset no matter what game you play. 9.5/10

This product does its job very well. Just the other day I completely forgot I even installed this as I just got it. After playing, I realized how hot my index was and I turned the fan on and, wow, was I shocked at how well it was blowing hot air from the headset. So yes. It does a really good job at what it’s mean to do. With that said, are you prioritizing heat or sound? I see many people say it is very loud. It is not extremely loud. It is louder than I had hoped. It is 2 fans, so sound is expected. However yes, the sound of the fans blowing can be annoying. Sometimes people can hardly hear it when I’m in discord, majority of the times, others can’t hear it at all. As for me, I will hear it when the game goes quiet. This fan ramps up speed, so it will get louder the longer you play. NOTE: As I can only post one video, I couldn’t post the video where I had not played games before, and as stated, the recording isMUCH louder than in person. If I heard that recording I would not buy this product, but in person is is about 1/4 of that volume. So with this: Pros: - cools down your headset VERY well. - has a mostly unnoticeable breeze inside the headset, however it is enough to keep the lenses from fogging - fans are not loud enough for most people to hear in such things like discord or recordings. Cons: - There is noise yes. - The noise is not as bad as it sounds in the video, but if it bothers you to hear the noise inside a quiet game, then I wouldn’t recommend. - The noise again, I said can most of the time not be heard, however after hours of playing, the speeds of the fans will ramp up to a level that can be heard sometimes. Not all the time. But sometimes by others. And the ramp up in sound you can definitely hear while in a quiet section of a game. My thoughts: I think it’s worth it. If the fan noise gets too loud, well there’s a button to turn it off. Simple as that. You lose the heat dispersement, but you can always turn the fan on when you are done playing to cool it down. Then off after the headset has cooled down. Or you can turn it off when you’re in a quiet part of VR and back on later when you’re in the action with noise covering the sound of the fans.
