Just to clarify, you have a four or five blade direct drive fan and not a clutch fan? It's hard to tell by the pics but it looks like the blades may still be inside the shroud. The optimum fan blade placement is 1/2 way inside and 1/2 way outside the edge of the shroud for proper air flow through the radiator and the blade diameter should be within about 1 inch of the shroud opening size.
Also are you using an aftermarket temp gauge?
With no accessories or auto trans there is no reason that new 3 row radiator can't cool your engine.
Has it gotten so hot it boiled over? Do you have to add coolant regularly?
