🖥️ 2 Packs Wathai 120mm x 25mm 120mm 5V USB Fan for AV Receiver, Cabinet, Game Console, PC, Laptop, TV Box, Projector, Router Cooling Review

I have a still air incubator that I am using for the first time to hatch chicks. added this little gem. Easy to use. No sound, no vibration. Fingers crossed for the best output speed!

They move a decent amount of air and are almost inaudible. I used these as a VR headset cooler and was impressed with the results. Email me if you need 3D printable files.

I still think twice the bandwidth of the 40x40x10mm module I bought from Wathai isn't bad for the configuration I envisioned. But the noise level is probably even more unstable than the 40x40x20 bought from them a year ago? I would recommend a possible 40 x 40 x 15mm modular upgrade, perhaps to overcome some of the vibrations of noise level instability and perhaps also to increase airflow by a few cubic feet per minute.

wanted to cool some electronic devices, but despite good airflow, it's too loud. Ideally, I should either have a slower fan or a larger, quieter fan.

They're even quieter than I thought, like a soft whisper, but they have more airflow than those noisy handheld fans you see at gas stations.

This was the third small fan I bought from Amazon because the other two didn't meet my needs (too much or too little airflow and/or too loud). This option is ideal for small closet projects. I would say something around 30 square inches with a height of 6 inches to 1 foot. Runs smooth and is not noisy.
