Most starches gelatinize between 60°C to 80°C. Including rice, which has starches that gelatinize between 59°C and 72°C.
Not sure where you’re getting the idea that rice needs to cook above 100°C, which is just plainly inconsistent with how most cultures have cooked rice for thousands of years.
Most rice noodles are formed from pre-gelatinized starches, too, in order to form the dough necessary for forming into noodle shapes to begin with. So those just need to be hydrated, and perhaps heated for personal taste preferences.
