you have a toyota powered Datsun mentioned, but a celica listed (cool car, btw)

What datsun are you talking about?

I wouldn't worry about the rad getting hot til about 200 to 220, which is where most OEM fans turn on, I believe. 192 is rather cool for the fan to turn on; a healthy cooling system will tolerate up around 230-240 with no ill effects. Keeping the engine that cool also cuts into the mileage; the fan pulling the extra amps olnly adds to the problem.

I would try a on setting of 210, off at 205. Assuming a healthy cooling system, this is well below its specs and you should see a boost in economy as a result.
