What I can tell you as an engineer and as someone with a ventilated hood is:
Whoever told you it wont work when the car is not moving is an idiot.
The simple fact of adding a "vent" to the hood will encourage better thermal conduction. Hot air rises, cooler air comes to take its place, gets heated by your hot engine/radiator, then rises to continue the cycle.
That is why some here have removed the weather stripping at the cowl to help alleviate the build up under hood heat.
You will see it while you sit in traffic. The heated air flowing out of your hood vent, even sitting still without the fans running.
When the car is moving, that process is made much more efficient by allowing the air to flow into the radiator and be vented out as you drive along. It will also alleviate under hood air pressure at higher speeds.
Plus your fans will encourage that flow while you are stationary as well.
The rain tray will restrict the flow a bit, but it will be better then nothing.

Totally agree with all this! When I had my stock hood with the Hines Hex Vents installed WITH the drip trays, the heat still escaped through them, as mentioned you would see the "heat waves" coming out while you were sitting still in traffic. I also removed the weather strip as mentioned, and now that I have a big cowl hood, the weather strip is still removed for good air flow.
