Racer,
I doubt those fans would be sufficient. Most after-market fans I've seen leave a lot to be desired. Here's a tip. Take some measurements, and try to find an OEM fan and shroud assembly that fits the dimensions of your radiator. The quality and performance are usually better. I'm using one from an Acura MDX, and it works great. Also, remember to use heavy gauge wire so the fan motor gets a full 12 volts at it's proper amperage.
Good luck!
