I mean that your fan curve isn't appropriate for a fan curve that's based on coolant temperature.

The temperature of the coolant shouldn't EVER get to 70C. In fact, it likely won't get above 40-45C. Mine never, ever, ever gets above 35C.

However, your fan curve doesn't start increasing until 40C, which is pretty warm for radiator coolant. And it maxes out at 80C ... and your liquid should never get that warm. Ever.

You have the coolant temperature confused with CPU temperature. They aren't the same. Certainly, they are related - the coolant cools the CPU by absorbing and carrying heat away to be exhausted through the radiator - but the liquid has a higher specific heat than air or metal, so more heat energy is required to increase the temperature. That's part of what makes liquid cooling ideal for both CPUs and car engines.
