Nismo thermostat does not cool your car better. It opens up the coolant passage to radiator earlier. Your engine will still reach the 180 degree, or higher depends on how you drive. I am not saying it is a piece of sh*t but just not necessary when the OEM unit works just fine.

E-fans vs. clutch fan? Hum, according to the fan test years ago, clutch fan does not run at higher rpm better as engine rpm goes up. At some rpm point the clutch is disengage, and it is because airflow at the speed the car travels outflows what the fan can produce. This is where stock clutch fan is better than aftermarket e-fan solution because in this situation, the clutch fan is off, free spinning by incoming air when the e-fans may stilling run because the thermo switch kept the fans on.



This is really funny. Lower efficiency because engine bay is hot? Our engine is not air cooled. It is normal that the engine bay is hot when the engine is hot...



Clutch fan is on when your car sits, E fan is not. Again, this does not make clutch fan better.



Again, you said "due to shrouding." So, do you have the result when your e fan setup is right?

You ran a shitty e fan setup and say it is shit, when you run a proper oem setup and say it is great? It's just like SR guys saying KAT sucks because they cannot handle boost as well, but in the real world, they are just as great as each other. A proper e fan setup will be as great as a stock clutch fan setup, plus you have easier access to the front of the engine. But in terms of cooling capability, they are equal if done right.
