Hi, anyone know some silent pwm dc cooling fan? better if PWM. 80 mm x 15 mm NOT 40 mm !!!

Any suggestions would be appreciated .

 

No fan is silent

 

Almost any fan can be whisper-quiet if you run it at low speed. If you want a high air flow rate you should expect some noise.
Check fan datasheets for noise level specs.

Define silent.

You can search vendor sites for fans of that size and then sort them on dBa.

That link (from Mouser) shows me many (you didn't specify voltage) with noise levels starting at 21 dBa.


...and although it doesn't really fit your post, I think these are pretty cool

 

Quiet is spelled N O C T U A

No such thing as silent fan.
