That's interesting. I'm going to guess that is at 5v unless it's using a transformer to boost it to 12v. A lot of fans run at 12v as 5v doesn't provide a lot power unless you are willing to pull high current at 5v.I looked at the advertised rating for one of those fans. It draws 80ma, so 2 of them should be 160ma.
Yes, I was referring to the entire raspberry pi's power draw. You could connect and disconnect the fans for a differential in power draw. Though I'm not sure how accurate or how many decimals of amps they support. Obviously, you would need to be powering via a wall wart to test it in that fashion.Isn't that for AC current? (judging by the connector on the front)
