You're right. But my thought was since the fans should have already been spinning from the wind blowing through them, there shouldn't have been much of a drop on startup. The AC compressor clutch may be the same way, but it only draws a couple of amps instead of 20+ amps and there is no noticeable voltage drop when it comes on as long as the fans are off.
