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 ### ⭐⭐⭐⭐⭐ Review *by A***O on 3 January 2026* ### ⭐⭐⭐⭐⭐ Review *by A***ー on 9 November 2025* ### ⭐⭐⭐⭐⭐ Review *by C***A on 19 January 2021* ## 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.
