Would a hood scoop help my problem?

Amazon.com: Derale 16759 Adjustable Fan Controller: Automotive
and this for the water pump
I cant find the other one but the only difference is one has a push in probe for the cooling fans and the other one has thread to screw into you intake to run water pump.
Been in for a year and half. no problems yet.
Edit:
Here is the wire

I tied the yellow wire directly to the battery because i wanted the fans and pump to run with the key off
