AC Infinity AI-MPF120A cooling fan — Quiet and effective for confined heat-producing electronics — RECOMMENDED
Update 3/2018: Expansion of the home network to include a home office resulted in another cooling fan for my crowded computer center (converted credenza, snug). The newest AC Infinity now has a variable speed switch, and costs less. Cabinet temps seldom exceed 5-7 degrees over the ambient room temp. The 120mm seems to be the best fan for the money.Original review:Small, but not so small that it can’t move air.QUIET!EffectiveOnce “installed” (more like placed in a cabinet), they are set-and-forget.I purchased 2 of these, being unsure att eh time how effective they would be in a renovated office credenza-become-computer center.Within the top half of this cabinet space, just under 3 cubic feet (9″h x 18″d x30″ w) I have a satellite modem (runs very warm), 2 routers and a switch, and a desktop refurbished as a firewall.Before stuffing all these components into this space, they occupied the lower half of a bookcase that sat atop the credenza, and all were clearly producing heat. Therefore the notion that these AC Infinity fans (or similar) would be required inside the smaller credenza space.I started by placing one fan in the rear of the cabinet to push air (cool air from below) across the very warm sat modem and router out to the front of the open cabinet, and there I placed fan #2 to help pull warm air out and into the room.Both fans run exceptionally quiet, and I needed to check occasionally to reassure myself they were still spinning. There is a subtle movement of air as well, not a breeze; simply lick the back of your hand and hold it 2 feet away and you will notice the cooling effect on your skin (an old IT “procedure” for detecting failed equipment fans, always works if not sometimes salty).An indoor/outdoor thermometer served as a great way to measure temps outside the credenza and deep inside (placing the remote temp sensor near to the warmest component, the sat modem in my case). For 2 days the interior cabinet temps remained within 6-9 degrees of the room temp.So I removed fan # 2 (front of the cab opening), all without more than 1 degree increase resulting.Bottom line: small but moves air (don’t expect a whirlwind or obvious breeze, it’s pretty subtle), and very quiet.The rubber feet on all corners eliminate any vibration noises or humming, and also keeps the fan from moving anywhere.The alternative might be the AI-MPF80A2 dual 80mm fans (52cfm total) if space is an issue.If heat is more of an issue than what I described here, consider the AI-MPF120A2 dual 120mm fans, 104cfm total.Depending on how my single 120mm handles heat this coming summer, I may opt for this dual 120mm fan setup.As for the optional fan thermostat and speed control, I simply let my fans run off any available USB port and do their work.Recommended, keeping your gear cool (or not hot) at this price is great insurance.

Hot Xbox One? No More!
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-Ã -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!

quiet fan. Excellent for external cooling needs.
I bought this for a couple potential scenarios. I have several fanless devices (switches, firewalls, etc.) that act up from time to time. So I think an external fan run off USB would be useful. The other is a mini computer with a custom fan that is no longer made by the manufacturer of fans. This allows me to put the fan external to the device and force air through it.The fan runs quiet on slow speed. In a quiet office/basement, I can hear the fan running (I listen for any new slight noise in case it indicates a problem). I’ll stop and listen intently to try to find the noise and then realize it is just the fan. The rubber pads keep it off the surface enough to get sufficient airflow and do not vibrate the device. Works really well.

This is super quiet and moves a decent amount of air.I can have this on all the time and never notice the sound. Keeps my receiver cooler and has prevented it from overheating.

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 !

Ho preso questo ventilatore per la mia collezione di Nepenthes. La cosa più sorprendente è la silenziositá, anche quando è impostato al massimo. A livello di potenza non è molto forte, quindi non adatto a spazi grandi, ma per una piccola serretta o terrario è perfetto. Consigliatissimo!
