Wathai 120mm Fan 120mm x 25mm 4Pin 12V DC Brushless Computer Case Cooling Fan

I needed 4-pin fans for a PC build - now here I am a few months later looking for quieter ones. (Update) At full speed, the fans reach 2560 - 2580 RPM (Spec says 2500) But the blade design isn't allowing for maximum air movement - so they are making more noise than they should be Oddly enough - I think the airflow direction arrows are missing? This is really a bad show in my opinion. I may try to lift them off of the case grill as this could be causing air friction. Update - The manufacturer reached out and offered a refund, which I declined. Nothing 'wrong' with these fans, they just need some updating / fine tuning.

The fan is okay I would rather have a quieter fan, but it produces good airflow which made me inclined to keep it.

It was a perfect replacement case fan. Came with everything you need to install it and also came very quickly. The power cord was a bit too short, but i made it work.

Fans works great for my ham radio.

Worked perfectly, nice and quiet. It could use to push a little more air I think, but for a typical computer system it will do just fine.
