Question How many Noctua 40mm fans would i need for an Itx Motherboard blowing down directly at it?

I am building a PC inside of a Fat Playstation 2. Wondering how many 40mm fans i would need to keep it cool in there. I was going to use Noctua 40mm fans blowing down directly at the board into the case. Its a tough question in my opinion. Cause who really knows. I bought 10 noctua 40mm fans. So i have 10 at my disposal. I don't want to cut large holes in the case. I could do 1 92mm fan maybe

the entire system specs would be necessary to start recommending/designing any custom cooling.

and what type of CPU cooler will be you using with it?

and what sort of intake & exhaust does this casing have available?

Power supply is in the case. it is a fanless power supply. I don't even want to get into how to get it to fit in there. Do at your own risk. In fact this whole build is do at your own risk.

Do you have a photo or a diagram of the case?
Fans do not cool.
PC parts do not sweat.

The purpose of fans is to move hot air and component heat out of the case.
If you can, place two 40mm fans on one side of the case, drawing in fresh air, and two on the opposite side exhausting the heated air.
The small noctua fans are very impressive.
