Maker Girl USA DC Case Fan Brushless 60mm x 60mm x 15mm 12V Quiet Output 6015

I bought these as direct replacements for the red sea fans used to cool the water in the aquarium. The fans I received did not match picture in that they came with 9 blades and not 7. The pitch on the blades were shallower than the stock blades and the air movement was significantly less than the original items. I had to remove them because the simply didn't move the air. The other specs of the fan matched perfectly (screw holes lined up). I didn't he think the blade issue would matter but it was significant.

Read carefully, Bare Leads!It was not to big an issue, just had to cut and solder the connection from the old fan this one replaced.Perfect fit and replacement for the fan in the surround sound box I bought a few years ago. Not all that quiet, but for the size I suppose its about as quiet as it gets? About the same noise or a little louder than the one it is replacing before the bearings went out. Took off one star because of the noise. Not sure if its the fans fault our just my high expectations.

Quiet and low current draw. Does not move as much air as I had hoped.

Works great and is very quiet.

Very Quiet cant even hear it
