Aftermarket fan generates far more CFM than mechanical fan and it runs when the engine is off until the engine drops and stays below thermostat setting thus preventing any heat soak.

Other than when my t-stat was broken open I didn't "need" to block the fan but it helps how quickly the car heats up. I like the idea of switching to two electric fans but I also like the idea of just taking off the mechanical fan for a couple months in the winter.
