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 ### ⭐⭐⭐⭐⭐ 静かで大風量！ *by on Reviewed in Japan 22 January 2024* 10GbpsのLANカードを導入した際に、一緒に導入を決めたシロッコファンです。LANカードに向けて、直接 風が当たるように向きを調整して取り付けました。USB-Aから入力電圧を貰って、12Vで稼働しているのですが、三段階にファンの回転数を調整可能で、たぶん、12V / 5V / 3Vにファンの電圧を変えているのだと思います。風量もしっかり有って、静音で、PC本体から電源を採るのでエコですし、コレが在れば、例えば夏場の熱帯魚の水槽や、外付けのHDDや夏場のワンコルームの冷却など、イロイロ利用出来るんじゃないか？と、思っています。 ### ⭐⭐⭐⭐⭐ Excelente produto. *by on Reviewed in Brazil 3 January 2026* Excelente produto, resolveu o problema de aquecimento no meu AV Receiver. ### ⭐⭐⭐⭐⭐ Molto buoni *by on Reviewed in Italy 21 June 2026* Molto buoni ## 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.
