you would want the dual fan setup from a '98 - '04 dodge intrepid. I believe all three engine options (2.7L, 3.2L, and 3.5L) had the dual fans. Actually any '98 and up Chrysler product will do - intrepid, concorde, LHS, 300M.
this fan style is also called the Ramchargers (RC) fans bought through Ramchargers (hi-perf Mopar stuff) when they were in business, but you can still buy these new from a dealer or used from the junkyard very inexpensively. OEM fans taken from a junkyard car are more reliable than the similar fans sold through ramchargers. there was a discussion a while back about the reliability of the that the dual fans that RC sold were the ones that Chrysler rejected - that these fans failed initial tests and were repaired and sold as "surplus", or "factory seconds" by ramchargers...
Do a search for dual fans in all open forums as there is some great info that does not need to be re-created here. Note that as you read the other threads, this is a topic that will have varying opinions. Most of the differences are in how the two fans are wired for operation (high speed and low speed operation), brackets for mounting the fan (top/bottom mounting or side/side mounting), and the depth of the fans. Some guys need really low profile dual fans while others do not. Some like the Spal fans for this reason. Another thread notes using the dual fans from a '98 Olds cutlass.
Here are a few existing thread with good info....

As you can see, there are several threads on this topic. If you go this route, use the Casper's dual relay wiring harness. Junkyard fans from the Chrysler products are about $30 - $40 from you-pull-it type junkyards.
