Hi and welcome.

If replacing the fan fixed your problem for a few months, it's possible your second hand fan has also failed.

Does the fan run at all...ever?

If you have air conditioning, when the air conditioning is turned ON the fan should run all the time.

With the air conditioning turned OFF AND the outside AIR temp BELOW about 30'c, then the fan should cycle on and off every couple of minutes. When the engine is warmed up.

If the air temperatures gets above 30'C the fan might run all the time.

If your fan runs at all, the fault is unlikely to be the fan.

If your engine over heats only while you are driving at speed (on the highway NOT in traffic) then you have a problem with your radiator.
