🔌 ELUTENG 120mm USB Powered Fan with 3-Speeds, 1500PRM, Portable Cooling for Gaming PC, Tablet, TV Receiver, Router, DVR, PlayStation, Xbox, Computer and More Review

I needed a small, quiet and slow fan to create circulation in the vivarium and this is ideal. It's quiet and generates just the right amount of airflow on the lowest setting. I will probably get more for other vivariums in the future.

I have a costume mask with lenses I see through that periodically fog up from breathing. I installed one of them in the mask, facing the lenses, and ran a cable through my suit to a phone charger sewn into my shirt. It worked PERFECTLY. A full day of clear vision at low speed and a light breeze at high speed. Very quiet. Even at high speed, the noise wasn't that noticeable and literally touched my head.

This fan still works. Harder than I expected. I wish it worked more with air, but I guess it all depends on what you're using it for. You obviously can't use this for large jobs. This is only good for small projects that may need airflow to prevent overheating or to dissipate heat from a small motor or similar.

This variable speed fan with a High, M, Low on/off switch on the cable is what I need needed. My NAS has two mSATA cards that attach to the back of the motherboard where there is no airflow inside the case and they get very hot. So I cut a round hole in the metal cover, attached a 4.5" speaker grill to the hole, and attached this slim fan directly to the speaker grill with small screws and rubber O-rings (see image). mSATA drives remain in good condition. and cool, and this fan is not at all…
