Could be any of the usual cooling system failures: stuck thermostat, air in the cooling system, clogged radiator tubes, gunked up radiator or condensor fins, corroded water pump impeller, missing undertray or upper panels, etc, etc...

I wouldn't call a 15degF rise normal, I'd call it an old car with mild cooling system issues. At a constant load I'll see 84-85degC (183-185degF) with the A/C off and 86-87degC (187-189degF) with it on.
Rising from 1/4 to 1/2 on the stock gauge definitely indicates a problem. Not a huge one, not a healthy cooling system either.

The main clutch fan probably does most of the work anyway, since the heat coming off the condensor will have the same effect on the thermoclutch as the heat coming off the radiator. The stock auxiliary fan is similar to the auxiliary fan used on most cars.
