If you where able to record so we could see rpm and/or airflow that would be awesome! Because then you could set the video up parallel with another and then just go play pause play pause etc. And I would also like to be able to compare the fans to others at certan rpm/volts. But then you would need to stay at one setting for a number for some seconds.

So if you could stop at different volts and let it be there for like 5-10 seconds so you can compare the fan with other fans at different volts and cfm (if you can include that). Like 3v, 4v, 6v, 8v, 10v, 12v. Maybe even more (I would like to have 5-10 seconds at each volt if you had the time and felt like it). It really don't matter if the video is 1 min or 5mins.

And at some volts you get some background noise that can be misleading at that moment. Do I make any sense? And rpm would be really nice to implement in the picture. And if possible also cfm.
Yeah, that was my first thought on the video, but after trying that I had to place the camera so far back to capture the guages, that the microphone lost all of it's sensitivity to capture audio from these low noise levels.

It's alot tricker than I thought, you almost need a camera that can use and external microphone and use a nice quality sensitive microphone to do it right.

I seem to have misplaced my wifes Canon S2IS, I think it actually has better audio than this JVC GZ-MC500U. It's a pretty cool little compact digital, but it doesn't have a microphone port.
