These fans are cheap... I mean... REALLY CHEAP. They are noisy, they rattle, and worst of all the wires break off VERY easily. I highly recommend that before you jostle them at all, you make sure the wires are safely stowed in the cable organizing clips and them use a drop of hot glue to better support the wires. If a wire breaks off while unpacking... peel back the sticker and attempt to solder it back on. Be extremely careful as the wires from the fan are run directly to the board and heating the solder pad to repair it can cause the other wire to fall off. Use as low of a temperature as possible to solder this joint (start at 200 c and work up from there). If you use too high a heat, the wire breaks and it's toast. As for the performance... just WOW... I've had terrible problems 3d printing with these fans in the beginning because no matter how much power I feed the heating elements of the printer, these fans are actually causing at least a 5-10 degree drop in temperature. I've had to cut back to 80% speed to print reliably. The noise level of these fans becomes tolerable at about 75% speed.
