Fridge works better. - 12V QUIET!!! Used to move air over trailer refrigerator coils. Paired with the AC Infinity Temperature controller to turn on when the cabinet air space reaches 84F. See photo. NOW the refrigerator coils has air moving over them and the temps inside the refrigerator stay more constant than before. Fluffy version: The Indel 12v refridgerator that came with our travel trailer was not keeping everything cool in a consistant manner. This was due to the heat bearing down on the outside of the trailer and the enclosed cabinet they installed the refridgerator. NO air flow basically. So we drilled a 3" hole and screwed this blower fan to the cabinet wall. Plugged it into the temperature controller that AC Infinity sells and stuck the thermometer in the cabinet cavity. Now when that enclosed airspace reaches 84F, the fan comes on, sucks the air out over the coils and blows it down onto the seat. It is not too hot or loud to sit next to. I LOVE IT. The inside of the fridge is now off by one degree top and bottom and keeps everything cool. No more bad meat. Believe me, when the lunch meat goes above 40F for over 30 minutes, you will get sick when eating it. Problem solved. I might put one in the enclosed cabinet where all the water lines are to push hot air into the space during the winter. Review: From Fiery Furnace to Cool Sanctuary: AC Infinity's Gaming Rig Relief - As a gaming enthusiast, I put a lot of time and effort into building a high-performance gaming rig, and I need reliable cooling solutions to protect my investment. AC Infinity's blower fans efficiently remove hot air from my computer's radiator, and their noise control and automation technology ensure the fans operate at the ideal speed to keep my system cool without excessive noise. The quality of their products is outstanding, and their engineering expertise is evident. I also use a AC Infinity Blower to keep an LCD backplate and GPU backplate cool under high GPU loads (leads to high thermal output). My CPU, GPU and LCD backplate temperatures have all remained well within safe limits, thanks to AC Infinity's efficient cooling hardware. I appreciate AC Infinity's commitment to delivering exceptional products and top-notch customer service. They understand the significance of keeping high-end electronics cool and have developed effective, automated, and reliable cooling solutions. My experience with AC Infinity cooling products has been nothing short of impressive. If you're searching for a reliable company to keep your gaming machine cool, AC Infinity should be your top choice.

I got 4.9V on H, 4.4V on M, lower than 4V on L and no output on OFF. **Q: can you use with xbox one,what is the USB type?** A: I put one of these on my Xbox One and it works great. It isn't loud at all and keeps my system cooler. It is a standard usb connection (not a mini or micro USB). **Q: Will this centrifugal fan work better than the equivalent axial version behind a HEPA filter? I heard centrifugal fans work better with pressure drops** A: centrifugal fans work better when a pressure difference is necessary ie your HEPA filter, this fan will work better than an axle fan and as the filter starts clogging up will continue to pull air longer **Q: Can you power the blower on full speed with the female usb port? i know that it is designed to power an additional fan.** A: No, the male usb is inline with the switch, that's how you connect it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quietly sucks the hot air out.

End of story, but not really. This product fit my need as far as cooling down my electronics that we're getting a little bit too hot in the spot they are in. The airflow to the electronics is now perfect and it is low key out of sight so appearance is not an issue. The instructions were very easy to understand as the black material matches everything that is around. ## Frequently Bought Together - AC Infinity MULTIFAN S2, Quiet 120mm USB Blower Fan with Speed Control, UL-Certified for Receiver DVR Xbox Modem AV Cabinet Cooling - AC Infinity Controller 1, Thermal Trigger for AIRPLATE, MULTIFAN, USB Fans and Devices.
