Wathai 120mm x 25mm 4Pin 12V Computer Case Fan DC Brushless Cooling Fan High Speed Replacement for Desktop PCs Case, AIO GPU Coolers

Bought this to replace that fan in my 850w NZXT brand PSU that I've had for maybe 11 years now. My original fan had developed a rattle. I didn't want to replace the power supply as it was fine otherwise.The specs for my fan were 0.5a and 2500rpm. This fan was the closest I could find on Amazon to the original spec. It works perfectly. Even though it spins a bit faster it is pretty quiet. No louder than my original anyway.Solid buy.

They move good amount of air and are relatively quiet.

This item was a perfect replacement. I used it to replace the cooling fan in bottom of upright drink cooler. My drinks were cold again. It hooked up just like the old one I took out. Very easy to replace.

I bought this fan to see if I could fix a portable dehumidifier. It turned out to be a circuit board failure, so I didn't need it after all. However, the kit is well equipped, that fan seems to be decently made, and the harness connector fit properly.

We got this to replace a fan in a mini fridge. Works beautifully, installed in minutes, quiet running. Came in a two-pack. Good value!

These appear to be working diligently to cool my air compressor baffle box. One of them is used as an inlet fan and the other is used as an outlet.

High quality product that was a good value. I got this to replace the fan for my opal ice maker. It worked great. I did have to change out the plug with the original, but instructions were included for that. The fan have nominal noise. The picture attached shows during installation.. The old fan is on the bottom right. Very satisfied with the outcome

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 beOddly 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.
