You can use my Mizu shroud, it is just sitting there. I have the upgraded FAL fans and a secondary radiator fan and my electronics are just fine. Now if you go adding crazy stereo **** then yeah for sure.
I think it's more how it gets wired up. Think about people like Dannobre who have a diff cooler pump, trans cooler pump, electric water pump, etc., etc. and have no issues. Those pumps draw a lot more amps than fans do.

The less you have the better.
I wont be able to afford those fans for another year or so though LOL.

Yeah but if the added amp draw is a non issue then it's a non issue. We shall see on Hoss's car, he has the larger Fal's and will have two other fans as well. But if the pumps the race guys are running don't cause an issue then I doubt he will have a problem.

I'm confused now... Doesn't our cars have a 40amp fuse for the fans to begin with?
How would a 30amp draw stress the system?
The only "extra" current I'm pulling is 5v 2amp for my tablet. Everything else is stock. No intentions of ever adding a sound system... I much rather listen to the engine most days anyway.

The more current the system draws the harder the alternator works, the harder it works the more energy is required to spin it.
The more energy required = less HP and less MPG.
The alternator is capable of handling that just fine, that's not the issue. the more amps you draw at idle the more your alt will need to create causing your engine to work slightly harder, which will cause your idle temps to rise.
See where I am getting at

I don't think that is how it works, the regulator adjusts to compensate for the engine speed and voltage needed at any given time, etc. Other than at idle, the engine speed doesn't need to increase to supply sufficient voltage during normal engine operation. Meaning if you are cruising at 3,000 rpms and you turn everything on, the RPMS or load will not increase.

.Give this a read if you are curious.

Basically the alternator is turning fuel into energy, the more energy you need the more fuel you need.
Think of it like a house, if you turn on all your lights and AC you are using more watts/amps. the more you use the more the utility needs to feed you, the more houses their are the larger the power plant needs to be.
Same thing with a car, the power plant is the alternator, and everything that needs power is a house.

Right, did you actually read that? That is about efficiency. But that is not what you are implying. You are implying that as voltage is needed to power certain items, the alternator has to work harder, thus taking more energy from the engine to supply that voltage. That is simply not true.
At 3,000 rpm a typical alternator can supply more than enough (too much actually) voltage than is ever needed so the regulator controls what is needed. When that extra voltage is needed the alternator does not require more fuel or physical energy from the engine to supply the extra voltage, it already has the ability to provide more than enough voltage.
And my 3,000RPM example is just a number pulled out of my head, from what I have read most alternators reach max output just off idle.

Anyways as your engine speed increases the alternator output increases its a sliding scale so at 5000 rpm the output is greater than at 3500 rpm.
Anyways back to the fans, they will only be on at idle, less draw at idle, less output needed from the alternator, this keeps the car running cooler and gas consumption lower...

You are wrong my friend. Stubborn and wrong, 
Just do some reading, most alternators reach max output at just off idle even with a full load on them. So you can increase engine speed all you want the alternator is not causing the engine to work any harder.
If I am cruising at 3,000RPM's on a flat road and I switch all my fans on, turn on the AC, turn on the radio, etc. I will see no more engine load than I already was seeing. And even if it blipped a little with the electrical load coming on all at once, the voltage regulator in the alternator would adjust and work it all out in a second.
It would take a **** load of stuff running all at the same time to get to a point where our alternator would be overloaded.
I know you won't read it but this is a good discussion about it.
