## Description

Ultra-quiet USB fan with multi-speed control and dual-ball bearings for long lifespan. Designed to cool electronics and components with optimal noise and airflow levels.

Review: Well built and very quiet - Note: Product purchased directly from seller AC Affinity and fulfilled by desertcart. I use this to improve the air circulation on my Xbox One, which is housed in a narrow TV cabinet. Even though the cabinet is not fully closed, the external of the Xbox can get very hot, especially during a long session. I placed this fan directly on over the Xbox's top vents, blowing away from the xbox. The build quality is solid. You can shake it about, try to bend or squeeze it, there is no rattling or even creaking noise. Around the frame, all surfaces that you can touch, it is all smooth, no hint of any sharp edges. When the fan is running it is very quiet. There is a mechanical switch built into the USB cable. This switch has 4 positions; OFF, speed 1, 2 and 3. At speed 1, you wont even know it is running. Speed 2, in a room without any other sound you can almost hear it, but it is still quieter than my external Western Digital hard drive. Speed 3, well, you can definitely hear it. Not that the motor is noisy, just the wind noise it generated, and if you have the TV speaker on, it will drown out the noise from the fan. The OFF position is very useful, because I connected to the XBox usb port, and the port is always powered, even when Xbox is in standby/sleep mode. With the OFF position I can switch off the fan when I not using the Xbox. This is so effective, speed 1 is enough to keep the Xbox cool. The fan comes with 4 rubber feet attached, it does a very good job of keeping the fan on top of the xbox. At £15, this us not the cheapest 120mm fan on desertcart, but I am convinced this is worth its price tag. It is certainly has done what I needed it to do and quality is great. Only question is, how long will it last, time will tell. I would highly recommend this fan to anyone looking to improve air circulation for AV devices.
Review: Great extra fan - I love it. It just does what I needed, it's quiet, after years still running strong, totally reliable and dependable. The speed range is great - at the slowest it's absolutely quiet yet still providing significant air flow, at the highest it's obviously no more silent but the airflow is marginally more intensive. I needed it for badly designed laptop with only passively cooled CPU in the back of the display side and I just glued velcro on the fan and the back of the laptop and would stick it on the back whilst working, did the job and made that crappy laptop usable eliminating constant down throttling.

## Questions & Answers

**Q: can this be plugged into a mains via a phone charger?**
A: Providing it's a USB socket charger. But as always I wouldn't recommend very cheap sockets

**Q: Could this be used to cool a motorhome fridge freeze**
A: It dissipates heat and keeps heat-generating devices cooler, like games consoles, HiFis, BluRay players, etc. I don't think it would sufficiently cool a small fridge freezer though.

**Q: Hi! i need an uk adapter for that fan but can’t find it on the market. can you help?**
A: I use the fan as a cooler in my bedroom, with a 3pin usb plug. Other than that, I’m sorry I cannot help you.

**Q: Is the fan moisture resistant, could I use it to extract moist damp air?**
A: I don't think it's water resistant. I would think the ball bearings works rust quickly.
