A faulty temperature sensor will automatically make the fan default to maximum speed as a precautionary measure. You also indicate that the internal temperature is 198° which is very high. There are probably other issues. Do take it to an apple store and have the exact problems diagnosed for free.

What’s the CPU temp on a MacBook Pro?

I also have Temperature Gauge 4.1 running on my MacBook Pro and that tells me that the CPU runs at around 50C if I pre-set the fans at 2500rpm, whereas the SMC fan temp readout is 128C which is the default Mac setting for a faulty sensor somewhere.

The function of cooling the system was to buy some time if the system didn’t run very long.
