It depends on the number of slots on the mainboard. There is space for 10 fans. No mainboard has that many slots. It is therefore essential to buy with a hub and to check the approved voltage of the slot (mainboard).

10x 120mm lüfter

There are different brands and different sizes, you have to decide which ones you want and how much you can pay for them. For example, I have 10 AF 120 elite from Corsair and I'm super satisfied.

Ps: the most popular brands are Corsair and lian li, and I would stick with the 120mm size if I were you as it fits 3 per side and looks better.

And watch your air in and out.
