I do agree with the extra heat because it sits right on top of the header basically.

The fans being on has helped keep the car cooler in hot weather. It stays right under half with the fans on. If they were off it would be slightly over.

The engine coolant temperature (ECT) will be lowered with the fans on, out of necessity to keep it from overheating and knock, but in the process the hot air is directed to the intake area, which raises the intake air temperature (IAT) and reduces power.

Once you start scanning for IAT at the upper intake manifold, you will see how this effect occurs. Also scan for "Delivered Trans Torque" to compare performance on hot and cold days.
