No worries then. We've had lots of people come here with the same concern.
If you want to actually test the fans, with the engine running, carefully disconnect the engine coolant temp sensor. The PCM will see an issue with the sensor and will now think something is wrong with it and as a safety precaution, turn the fans on low speed. This will also cause the check engine light to come on. But will go away when you plug it back in.
