They have three speed settings and are very quiet on all three. Will definately run from a USB socket. I have mine running in this manner no problems at all. What I did and I would recommend is to purchase the dust filters to use with them --> https://www.amazon.co.uk/gp/product/B076BJCYBY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 These clip on and capture all the dust that the fans suck in. Saves you having to clean the blades so much and also if you are using them to cool a case then it stops the dust being pulled into the case. HTH. **Q: I intend to use on my original xbox one. which way is best to use these when placed on top of the console? to blow air in or to extract air away?** A: I've not got an Xbox One, but on other devices (Sky Box and home cinema amp), they run noticeably cool when you extract the hot air away. I think not as much air will flow through trying to blow fresh air in, but it's easy to try both ways. **Q: Can these fans be left running 24 hours a day** A: Yes I believe so. They are frictionless and appear to generate no heat. You could link them to a thermostat and they activate when required if you are nervous at leaving on. I have similar fans in my hub rack that are on 24-7. **Q: Would they function well in high humidity? Are they likely to rust?** A: Not certain, electronics don't usually do well in high humidity. Having said that they are made of plastic and if your going to be using them to keep your amplifier cool there shouldn't be a problem. These are very good fans. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent cooling power *by on Reviewed in the United Kingdom 22 June 2026* These fans were brilliant.
