The correct spec toothed belt would hold up ok,flanged pulleys would prevent any side slip,but the train needs to be spot on,ie every thing lined up and securely held.Twin pulleys on the drive shaft,belt to each fan.You could use a single double sided belt,even set it up to contra rotate,but that would mean idler pulleys and a complex belt path.Only advantage is it would be easy to install a tensioning device.
I'd advise against flex shafts at these speeds,get every thing lined up and use intermediate bearings.
