How much ventilation to remove the beautiful smell?

Im going to change things up in my next grow. I have just ordered a mars II 400w so i can see what this "future light" is all about . Im growing in a tent 1.2mx1.2mx2m = 2.88m³ and i have used a 350cbm/h fan. So.. since im swapping to LED i wont have any heat issues and that means i wont need as much ventilation as before. Will it be ok to install a 175cbm/h fan and will it still be removing the smell? Ofc i have a carbonfilter too

I'm wondering about this too in a slightly different vein. I rely on tha Hid heat to make my thermostat/fan kick in and ventilation/cooling system work. You need fresh air as well -of course...

Put a speed controller on your existing fan

I have been looking at a autotransformer. Way cheaper than buying a new fan

Now i just need to learn how to install it without blowing up my house. Safety first.

I will convert 230v to 100v. My fan pulls 350cbm/h.

Does that mean it will pull around 150cbm/h at 100v? (350cbm/230v) = 1.522cbm pr volt. (1.522cbm *100) = 150cbm/h?

Just logic thinking, but can i even calculate it like that?
