I have a 2000 Boxster.
Today in 28 degree temperatures in traffic she got pretty hot.

I had to pull over to cool her down.
I hear a fan in the engine bay behind me.
What does it do? How does it cool the motor when the rad is out front???

There are fans on the front rads????????

How do I check them?

To test...turn on car, then turn on a/c. Fans always run then at low speed,

If one fan doesn't run, then its either the ballast resistor, the fan motor or the fan relay. You can test the relay by swapping it with the relay from the working side.

The fan in the engine bay is to move air surrounding the engine. Air is drawn from below and pushed out the passenger side vent. There are 2 fans out front, one for each radiator. The S model has a central rad as well but no fan behind it. Follow Thom4782 advise to test the front fans
