Noiseblocker NB-BlackSilent Fan XR-1 60mm Ultra Silent Fan 1600rpm 3 pin 11 dBA

Is this 12V? I am looking for a 5V version

What is the depth of the 60mm fan? I need 60m x 10mm deep, although 15mm will fit

why the three wires,

What is the recommended amperage? Will it work alright to replace a loud fan at .27A?
