Nice. I figured up that my case is going to be a 13" wide x 13" tall x 18" deep. So on the front I have a few options: (basically 332mm (w) x 240mm (t) of space).
Front Options
6x 80mm fan (stacked)
2x 120 mm fans
2x 150mm fans
1x 160mm fan --- 1x 200mm fan.
I am intrigued at the concepts of a 200mm fan
So if I did one 200 mm fan on the front, here is what I have as far as options on the top and back. (i was trying to avoid this time around of using the sides for fans at all)
===============================================
Top
I can fit it looks like:
4x 80mm fans They would basically be toward the front on the left and right of the dvd drives
or
1x 80mm to 150mm fan (if I choose to not full up the narrow channel like areas)
or
1x 80mm to 150mm fan + 4x 80mm fans.
The top has a few spaces along the sides of the dvd drives on each side. Then just large open space, basically over my gpu/pci slots.
===============================================
The Back
The back has two odd ball open spaces to use. One below the psu right behind my cpu cooler which I would love to have a good fan here.
The space under the psu AND the space above the PCI bays each allow for
4x 80mm fans
1x 120mm --> 160mm fan
Is it bad to have mis matched sized fans for intakes/exhaust? I am pretty sure the 80 mm fan monster setup is going to be far to loud to be practical regardless of how much air but i mentioned just in case there is a wonder fan out there
Besides less wires inside = bonus!
The top is also tricky for me to decide on. I don't see the frontal ones pulling out much hot hair because it hasn't even blew over the motherboard at that point yet, but it will by pass the rack of 6 HD bays. I mentioned for your info but I think it'll end up being pointless. The space towards the back of the pc on the top which is above the gfx card/pci slots could house a nice exhaust fan, as well as the back.
I just read here:
http://www.technibble.com/case-cooling-the-physics-of-good-airflow/
That to get a good airflow and what they call a "positive pressure channel" I take the cfm from the intake, and subtract the cfm from the exhaust.
I figured up, I could go
200mm in the front (just one)
Then
3x 140mm fans
It would leave the case at -80.2 cfm from the intake.
Am I reading that right?
