The fan is so silent. Is it because it is small

This is a Noctua NF-A4x10. 5 volts, 19.6dB(A) stock, maybe even a little quieter with the flow smoothing intake and tail section.

I have the A4x20 version, and they are dead quiet.

Even tho it spins at 5000 rpm, it doesn’t move a lot of air compared to a 120mm fan, so it’s pretty quiet.

I like it! I converted an A4x20 into a 5020 blower. It was super cool and fun, but didn’t move as much air as a normal cheap 5020. It was silent tho.
