Xbox One is a fantastic gaming system, but man, does that little black box get hot! Especially after 12-16 hours in Fallout 4. Yes, the XB1 has a large internal fan, but it's lethargic: it draws a small volume of fresh air and pushes out an equally small volume of hot air out the top. Some say this is enough: 'That's way they designed it!' I know, I've read all those articles (and so have you, I'm guessing). But you're reading this review now because, like me, you've come to realize that 'design myth' is just that: a myth. I'm being polite here; you may have another word for it. Put simply: That box is too damn hot. And heat is killer for high-end electronics.
My solution is simple and relatively inexpensive (especially considering the cost of a new XB1). It's also two-pronged:
PART ONE: This fan. Place it on top of the exhaust vent to help pull hot air up and out. (Use a deflector to redirect air flow if your XB1 is in a cramped location like a bookcase.) Fan can use one of the two USB slots on back of XB1.
PART TWO: (and this is important) A side vent fan of some sort. Blowing in. Another 120mm sitting on the outside? Maybe. It's so quiet, I may try that. The fan I chose however was the DOBE integrated side-vent fan. Available on Amazon. (There are several fans of identical design which makes me think there's one manufacturer and many distributors - I chose DOBE because their ad was almost in English). Snap out the old vent/dust cover (use a thin butter knife and throw out the plastic pry included) and then snap in the fan unit. It's a good fit and utilizes the side USB port (I didn't even know it was there). The design gives you back two USB ports to compensate but I haven't tried them (I've read there may be data transfer issues vis-à-vis external HDDs but that's beyond the cooling focus here).
The two fan approach works quite nicely for me: At the end of a 12-hour Fallout 4 session recently, I lifted the top fan off and put my hand right on the exhaust vent and could barely discern the heat. What a difference!
DOWNSIDE? Only from the integrated side-vent fan: A slight fan-hum is audibly discernable even on the low setting. I think I can live with it though given the results. The AC Infinity fan on the other hand is whisper quiet. When the DOBE stops working I may just buy a second 120mm and stick it along the side vent and see how that works. Hope that helps all you XB1 gamers out there have a cool summer!

I have a few of the earlier model of this fan, in 80mm, 120mm, and 140mm.

There are some differences between the older model, and the newer model of these fans.

- This fan was already assembled. The earlier model, I had to screw the fan guards and feet on.

- The older model was only on/off, this new model has the option for Low, Medium, High, and Off.

- The older model included a USB-to-AC power adapter. This new model lacks the adapter.

So far, this fan is nice, I like the variable speed settings. I like it was ready to go out of the box. I used a USB-to-AC power adapter with this new fan, since the switched item I have it cooling, only has a switched power plug, nothing USB switched. When this 120mm fan was on High speed, it seemed a bit louder than my old model 120mm, but I didn't compare the two too much.

I bought this to replace an earlier model of the 140mm AC Infinity fan. I found the 140mm fan to be noticeably louder than the 120mm fan, the older models I own. After that, I decided that when I needed more fans, or needed to replace a fan, I'd buy 120mm, no more 140mm. Well, a 140mm fan began to get noisier and noisier lately, so due to the fan increasing in noise lately, I decided to replace it with this 120mm fan.

I was happy with the older model of these fans, though I preferred the 120mm, to the 80mm and 140mm. 120mm had a nice balance for cooling and low noise. So far, I am happy with this newer model fan. The variable speed switch is nice, shame they took out the USB-to-AC power adapter, but that's OK, I still have some from the older model fans, and it's an easy enough item to find and purchase separate.

These fans do their job well, cooling the electronics I want them to cool. All of them I have in use, are pulling air through the electronics, though, not pushing it.

I mounted this to the top of my sub amp in the center console of my Suburban. 750 watt class D. Didn't run hot before but warm. I used dab of silicone on the 4 feet and it seems to work fine. Totally quiet. Doesn't move as much air as I thought it would but way better than nothing. Seems like a quality motor and bearing. Easy to use with USB plug. I just plug it into a small lighter adapter when it is warm out.

Reviewed in France on April 23, 2022

Je ne laisse pas souvent de commentaires mais là je prends la peine de le faire car ce produit est vraiment excellent.
J'ai essayé plusieurs tapis de ventilation pour refroidir une udm pro avec des résultats très mitigés. Au mieux j'ai réussi à obtenir un abaissement de 5°c de la température du cpu mais avec un bruit largement perceptible.
Avec ce ventilo j'ai un abaissement de 8°c du cpu dans un silence absolu.
J'ai positionné la vitesse sur médium.
Possible que j'arrive encore à gagner 1 ou 2°c en irritant la position hight mais totalement inutile dès lors que le cpu est à 42°c et que le châssis de la machine est froid (avant je pouvais à peine poser la main dessus...).
Bref je recommande ce produit.
S'il y avait une étoile bonus je l'aurais mise !
