Second that dual fan with a SHROUD! any shroud would help, your fan is pulling through through less than 50% of your radiator area. If you pull the fan back (or get a dual setup from a Neon/Breeze/cloud car) you may still have clearance in the middle for the water pump hub, and will be pulling air through 100% of your radiator area. Pusher is the same bad design. Small area gets cooled.
