Fan placement for optimal air circulation

It really should not matter where you place the fans - it's a box so eventually you will get circulation. I think the problem is as noted above - the current fans only run when the humidifier is running. You simply need to run the fans (new or existing) for longer times and/or more frequently.
As your humidification devices are at the bottom - you are naturally going to get higher readings there.

It's my belief that facing them up on one side and down on the other to create a circular effect works best.

Depends on where your air gaps are going to be.

For large cabinets like yours, I would think that vertically positioned but located at about half-way up the back corners would be good. This will both draw up air and also blow out air, which should give increased air movement. I've also seen opposite corners where one blew up and one blew down, but I think that this causes air gaps in the center.
