Looks like your choices are to either trim the shroud back to expose more of the fan, or reinstall and correctly setup those electric fans. If your e-fans were still running at speed, they weren't setup properly.

Yes but his fan is running at full force 100% at highway speed since it’s direct drive .The op also stated that with the electrics they would come in at highway speed .Electric Fans should not come on above 40mph let alone highway speeds unless you are lugging going up hill towing . That indicates a radiator problem, it may be a combo of both .

I can drive all day at 40 and up fans never kick in temp may climb going up hill but never go 190 in the head . The water temp would be 10 degrees lower . I do have a Dewitt’s 2 row with 1.25 “ tubes .

Also the OP stated the temp went to about 215 max at idle which is pretty much normal for any engine . There’s always a rise it head temp after running and coming to a stop
