## Questions & Answers

**Q: Is the daisy chain port full, unswitched usb power, or is it controlled via the speed control? as it's located after the speed switch it wasn't clear.**
A: The port is controlled by the switch. 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.

I bought 4 Ac infinity Fans for my receiver and an for another amp. However I only needed two. One for the Receiver and one for the amp, as they draw out the heat more than adequately . I highly recommend these. If you have heat issues or just want to make sure your equipment doesn't overheat. Perfect for Home Theaters.
