The minor gripes, though, the quality is worth the price.
the fan is bruillant and the rotating part tends to dissociate from its engine.
Once that happens the game with propellers slide on the motor shaft causing huge loss of performance and a significant increase in noise.
However, a drop of glue is sufficient to repair the MECHANISM.
Another annoying is that the fan may start to vibrate with the USB connector, increasing even more the noise generated.
