My chip cooling fan bearings went bad (noisy, and oiling didn't help). I found a "chipset" cooling fan that fit (eventually), and works fine (just left the yellow "sensor" lead floating). The question: is there much current rating difference between a chipset fan, and a video chip fan?

These guys always have a rating sticker on the reverse of the fan so you can seen exactly what they draw.
In comparison to a GPU fan well that depends on the graphics card, probably similar rating to fans fitted on GF2's and 3's Radeon's upto say a 9600pro but some of the higher end GPU's like the FX5900/5950ultra's Radeon 9800XT etc have much bigger fans.
Why do you ask? are you thinking the header might be close to it's rated limit?
It takes a pretty powerful fan to exceed the header limit.
And those fans that are too powerful usually come with a split 3pin fan header for the sensor and a molex for the actual power, like the Thermaltakes and infamous Delta's.
Manufactures often state max supported wattage for fan headers in the manual (might take some finding tho)

I was just concerned because this fan plugs into the video card itself (small two pin plug). I know that there are stickers on "chassis" fans that show the currant drain, but there was nothing on the original fan or the "chipset" fan. The fan (and coils), are the same size. The heatsink itself is larger (and it is a lighted fan - kind of useless in a solid case). It seems to work OK, but I was just worried about over-taxing the traces on the vid card.
