KEYFANCLUB High Airflow 120mm Fan 12V 3000RPM Dual Ball 120x120x25mm 12cm 2-PIN Connector DC Brushless Cooling Fan

I have zero bad to say about them, they're easy to install with just a + & - wire and they keep my amps planty cool. I mean they're fairly loud but I can barely hear them with my back seat up and I feel like some noise should definitely be expected given the price

They do move a lot of air but the blades are very brittle. I was showing it off to my grandkids and one of them stuck a finger in the blade accidentally and it broke one fin right off. On most fans that would just stop the fan but not damage it.Update: Seller offered a refund without even being asked! Prompt response. So they do stand by their product! So I went from 3 stars to 5.

Move a lot of air. However it's loud.

I ordered this to replace a cooling fan that was starting to go bad. On initial review, I liked the idea of the high cfm rate and the supposedly low db rate. After installing the fan, it works fine and moves a lot of air, but if this is supposed to be a quiet fan, I'd hate to get one that is noisy. I'd like to return it, but I had to cut the wire to my old fan to get it out of the case, so...... Anyway, I will be looking for a quieter fan to replace this one.

Does move a lot of air. It is noisy. Can't switch black+red , unidirectional. I broke one because leads were backwards and got a finger in when switch the leads. Works fine in my rack.

This is a high cfm fan. Works great for electronic or computer applications.

They're a little noisier then expected but they move a lot of air. I use to use two 12v muffin fans but with these one did the trick.

Works fine, good air flow and was what I was expecting except is somewhat noisy.
