Fans are quiet but bulky. Bought for a terrarium - the size didn't suit me. However, I think they will work well when used (as intended and intended) for cooling electronics or in a small Ikea cabinet style greenhouse (which I will most likely use them for). Flaws in design and price. 1st - I didn't like the forced electrical cords and connectors if you split dual/branch cord fans (wouldn't be so annoying if there was more room on the connector) 2nd - I didn't like what the fans don't include - something to plug into a standard outlet. If you are interested in being cheap for DIY or DIY projects, I would recommend finding another product. If you use it as intended, you should be satisfied; although I'm sure other customers would also appreciate being able to use one while not needing the other. I found 4 fan packs at Revain from another seller with separate $9 USB adapters with a 2 decibel noise boost - two super sticked together to get the same/better airflow. The double sided 3M foam worked great to install cheaply and keep the noise down, overall happy with the other product and won't be buying again.
