Car running hot would it be a good idea to switch to HHR fan?

I didn't look at the pics that hard last night but you need more air flow that's for sure. I bet a funnel type (stock) shroud would do wonders. The fan in the top post would do it I bet. I gave up on the electric fan and install a mechanical fan. I just wanted to drive my car and not have to worry about over heating. Whatever horsepower I lost by installing the fan so be it. It's not a drag car anyways. lol
