Engine compartment fan

Does anybody knows how I can switch on the engine fan for better cooling at the engine bay?
I have a 997s cabriolet supercharged and I want to cool the engine bay for more safety and cooler temperatures at track days in the summer
Thanks in advance

Yes. When the switch is off, the fan will function like before. With the switch on, it will run continuously, lowering your engine temp by at least 20F over ambient temp, according to 1999Porsche911.

Before the mod, the fan will turn on only at a certain Intake Air Temp (IAT). By then, the IAT is suboptimal for consistent power output (ie: heat soak). After the mod, it will function the same way, unless you manually turn on the switch for the fan to run continuously. The advantage to running the fan continuously is that the IAT will be lower consistently, thus producing power more consistently.

Only problem I see is if the fan runs continuously, eventually parts will wear out. But, remember, this mod works best in stop and go traffic and on hot summer days, thus you are not really running it all the time.

Just make sure about which relay to connect to since he did this mod on a 996.

What's your opinion for this rear wing?
Is it better for the mod that you told me.

Ideally, you should do both mods to maximize IAT cooling and engine coolant cooling, but try the engine fan mod first to see if you're satisfied.
