Amperage and RPM questions...

Question

Hi, 

 

So I got a couple of fans laying around and I am wondering if the

amperage has something to do with the maximium rpm of the fan?

 

I got for example fan 1 that's rated 0.15A and fan 2 that's rated 0.6A. Does

this mean that fan 2 spins at a higher rpm and therefor is louder than fan 1?

 

Please let me know...  :rolleyes:

Volts and amps do affect rpm.

So 'fan 2' would be louder?

The fan will always 'sip' the amperes it needs to work. Giving it more or less is not up to you. To regulate speed, regulate voltage (unless the fan used is PWM controlled)

Some fans are more efficient or have lower power consumption depending on the motor used, but it doesn't translate to RPM or performance.
