🤫 Noiseblocker NB-BlackSilentFan XM2 40x40x10mm: Silent Fan with 3800RPM, 14 dBa Noise Level Review

With its pros. very compact. The sound of the motor and the air flow is audible only when leaning against your ear. Relatively inexpensive Different cons: I was expecting more airflow. Nothing included other than screws.

I really like the fan but I gave it 4 stars because it doesn't seem to move as much air as the one I pulled out. It's very quiet and moves enough air to do its job, but the fan I took out moves 2 or 3 times more air than this quieter fan. Overall I'm still happy with it and it serves it's purpose.

Nice and quiet, the airflow is not very strong, consider that. That's what I expected. I'll see if it holds up. Edit: Well, it didn't take long. The bearings now make this whirring noise and sound like a truck when starting.

Excellent quality. I wish they came in more sizes. Worth every penny. The second best upgrade for keeping a 3D printer quiet, after engine vibration dampeners.

I bought this for my 3D printer's front fan and it worked perfectly! it is small but powerful and very quiet. The fan's quietness does not affect its performance in any way and my 3D printer has become even quieter as a result! I've tried other fans on the market and this is the best and quietest I've found (and the price isn't bad either)! The fan is everything I hoped for, good quality, quiet and affordable.

The noise blocker fan did what it was advertised to do. Works well and is almost silent. I wanted to use it to cool the heatsink over the hot end of my 3D printer and provide adequate airflow for the vent to cool the parts on the underside of the fan shroud. The fan doesn't advertise that it has enough power for my application, so I can't fault it for being underpowered. If I was just using it to cool the heatsink it would certainly work as my heatsink doesn't need much airflow to keep it cool.

These fans are installed on my Wanhao i3 duplicator and Creality Cr10s! Sometimes I have to triple check if the fans are on because they are so quiet! I used to think Noctua fans were the way to go, but these fans are way better. It's an amazing color, the cables aren't two lost pieces of wire, they cover all kinds of protection and that's what makes it amazing! Did I mention how great the color was?
