| I use a 21" fan from a ford crown victoria that I picked up for 35$ at an "auto recycling facility". It's big, it's quiet and it fits. I have no over hearing problems at all with or with out AC. Most people believe an electric fan Free's up about 5hp. After looking at all the electric fan options from Z vendors, they just seem cobbled together from off the shelf parts and were expensive. I used a 100$ flexalite fan controller and with some misc parts my total cost was under 200$. [ http://www.icsamerica.com/zstory/images/300zx%20radiator%20001.JPG ]
