## Questions & Answers

**Q: If I turned one of the fans around would it act as an exhaust to remove the hot air from an enclosed cabinet?  Thanks.**
A: Yes indeed it would, the fans are completely reversible and can therefore be fitted either inside or outside the cabinet.  I fitted mine inside as there was plenty of space behind the home cinema/DVD recorder units, and it works faultlessly on just the low speed in keeping them cool.

**Q: Will these fans work for 2 consoles on the back of av cabinet as an exhaust using a usb y splitter for power? to both?**
A: These fans have are hard-wired together. With the option to days chain another set as they have a female USB in lime as well. They have three speeds.

**Q: I have a water cooled gaming pc under my desk and need a fan to give air flow on top of my pc is still powerful enough.**
A: Providing there is somewhere for the air to go (i.e. the PC is not completely closed in) and not knowing how hot it gets on top of your PC, I would have thought so. They are great fans, especially if you get AC Infinity temp/thermostat control switch so it kicks on when the temp exceeds a preset threshold.  They do bigger USB fans, I think the next one up is 120, if you want a step up. I personally think they are the best USB fans for a good balance of power and quietness.

**Q: How much power do these consume?**
A: sorry I really don't know, but they do work well
