ELUTENG Dual 40mm USB Fan with 3 Speeds Adjustable 5V PC Fan Max 5500RPM 40mm * 40mm * 25mm Mini Case Fan Quiet Computer Fan Compatible for PC, TV Box, Router, Xbox, PlayStation

Fans work fine for my application, not too noisy either. They work in parallel which is another reason I bought them.

Using this for a Vive Wireless Adapter to keep it cool. There's a thingiverse design for a similar dual-fan product which I haven't printed yet, but I'm excited to try it. The fans themselves work well. The noise level is a little higher pitch than I expected, though. I worry that this might be a sign of the fans being roughed up during shipping or something like that, but they work really well and are cheap, so I'll use them until they fail. Not much else can be said about this product. It's 2 fans with a long cable and a switch. It's easy to power and easy to find a use case for.

The media could not be loaded. Definitely working fansSmall compact able to to carry around for personal use/ business purposesNot too noisy until you get to the last speed(Brinks lock used for scale)

using in my 1000 cigar humidor to move the air around the cigars, works great. very quiet. i use on low and it circulates the air perfectly. i have 4 hygrometers placed at various locations in the humidor and they showed an increase of 2-3% RH in the cabinet. works great for my needs. will see how the longevity is.

I was originally planning on using these to help ventilate my AMS unit, but the airflow is too low.I eventually installed these in my wife's shoe closet to ventilate a wooden box with expensive heels.Not a total loss at the end of the day.

Used for my daughter’s lizzard cage for air circulation. Very small but exactly what looking for. Works great!!

It worked beautifully and it came with everything it said it would. Perfect for keeping my 4 external NVMe enclosures cool. Absolutely quiet too.

I used to order these all the time for my art projects. They USED TO be strong and reliable, but recently with my orders I wasted $20 on 2 weak fans that barely work. The low setting barely blows any air and it barely different then it being on high. These were a waste of money and ruined my project. They decided to change the power of the fans because people complained about the noise.... fans come with noise no matter what... its such a lame excuse to change the power of the fan. can people not concentrate with the blank noise?? really?? They have lost a long time customer with this decision and they dont care... IF you want it lower, theres a low function for a reason... now these fans are useless from how WEAK they are from how they used to be. Sad and pathetic.
