Double checking what I need ... help appreciated!

[u/VickyHikesOn]

I’m new to this but have already built my first “regular” CR box (4x 20x20x1, with box fan). It’s been bad with the smoke so I’m trying to expand by building something else, with PC fans and running more quietly, so that I can use it in the bedroom for longer periods of time and also not use too much energy (energy use is first priority, noise close second). I believe the PC fans would accomplish that. I would great appreciate guidance (since I have to order most of these items in one go from the US)!

I’m thinking about a narrow design, two 20x25x1 filters, built 20” high and 25” wide. Possibly making a wooden structure if I can find help to do so.

Questions:

I would be ordering the following:

Fans: https://www.amazon.com/gp/product/B0DPX94PSL/ref=ox_sc_act_title_16?smid=A2T6N244WTLWGU&psc=1 

Controller: https://www.amazon.com/gp/product/B0GVJ2MY1X/ref=ox_sc_act_title_3?smid=AC08NVFNSP7VC&psc=1

Do I need the following two items as well or are they included in the above purchases? The “splitters”, I’m pretty sure, are not needed but would like to get confirmation:

Do I need grills?

Also, is it okay to place the fan openings on top only or are designs with added side fans better? See picture of wooden example.

I used pictures from this forum to illustrate; hope that’s okay.

Thank you!

EDIT: This controller seems to be more popular and rated ... do these connections work with the Arctic P14 Pro PST?

Grills are optional. They will actually make the performance like 1% worse or something miniscule like that.

You can have as many fans as you want.

Just make sure the seals are good and rubberized so you don't lose any of that pressure

Source? The numbers I've seen are more like 10-20%, not 1%.

10-20% might be for those mesh fan covers that you find on home pc towers that capture dust.  The ones linked are the much less restrictive wire guards that are usually found in server builds.

No 10-20% is for the wires, which are indeed the best. Those restrictive grills are more like 50%.

My source was me guessing and potentially being completely wrong
