You won't ride and NSR anywhere much hotter than Thailand, and a stock (delimited) NSR will run there with nothing more than the OEM radiator.
It doesn't exactly get scorching hot in the UK even in the middle of summer, but with the F3 'box and a 1st gear good for over 60mph, my MC21 needs plenty of rpm in slow moving traffic and has never cooked itself. Steve's '21 makes well over 70hp and still runs a stock rad too.
It was pretty cool on Blue Haze Day at the Ace Cafe last year, but both bikes happily tootled through central London traffic. Fans are for the bore-strokes.
