Question 1

What is the recommended voltage, Standard 12V?

Accepted Answer

Without using the included inline resistors the input 12V. This will produce the most airflow along with the most noise. If you use one of the included resistors, the input voltage will drop as will the airflow and noise. The usage just depends on your project goals. HTH

Question 2

First-time builder here. My fan does not have an arrow on it. In which direction does the fan blow air?

Accepted Answer

It blows out the backside where the wires plug into the fan motor.

Question 3

what is the height/depth of this fan please ?  I presume the housing is 40mm X 40 mm

Accepted Answer

I'm fairly sure it's 10 mm -- 40x40x10 mm is more or less standard for this type of fan, and I have fans from two other manufacturers that are drop-in replacements for this model.

I'd know for sure if they weren't all installed in kit that I'm currently using, but I'm more or less positive 10 mm is correct.
