update on overheating- now what?

[cnavarro]

At speed, the fans don't need to be run. In fact, I'm pretty sure on a spec Boxster, they remove the fans. At low speeds or stopped, having the fans run will help, and in fact, with the a/c on, at least the passenger fan is always on. I made the same observation that the temp would rise when the a/c was shut off at a stand-still because you're eliminating the last bit of airflow over the radiator. Theoretically, setrab does make some very small fan packs that would fit nicely on the 3rd (center) radiator to help with low speed/ low airflow scenarios.

The fans typically don't turn on until 210F, or at least that's what I observed in my car. I agree, this is too late. I would prefer they came on much earlier.
