Electric fan sender???

[airbrush guy]

I am about to install dual electric fans on my aluminum radiator to keep my Hudson/Caddy 500 cooler.
Would the outlets in either the rear corner of the driver-side head or the plug on the front passenger-side just below the thermostat housing (see pics) be better?
Thanks

Excuse my slowness, but better for what?

As in...can either hole be used?

My perspective says yes, you can use either hole - for the temp sender.

Thank you Darius, I guess my question based on my unfamiliarity with Cadillacs was simply...Can a fan temperature sending unit be placed in either of these holes , is there water behind them? And would either hole give a truer temperature reading than the other?
Thanks for your help.
