Hi! Welcome to Geekswipe. For your question, of course, the answer is yes. Aluminium has a high thermal conductivity than steel. So the aluminium radiator certainly helps. And with the added benefit of another radiator with a much larger surface area, you can expect a faster convective heat transfer. Larger the surface area and higher the conductivity of the heat exchanger, the faster the heat transfer is.
If you wouldn’t mind, can you post the picture of your setup? Just curious!
