Positioning of fans

[priv4cy]

I have an ms industrial fighter case, which has one spot for a fan on the back, 2 in the front and one on the side panel. My question is how should i put them, which ones to put for intake and which for exhaust. Also are these fans good https://www.gigatron.rs/kuleri_i_oprema/ms_industrial_cooler_case_12cm_fan_blue_led-86019     ?

Are the fan sizes the same? Or are the two on the front bigger?

Also, generally, you want an even intake and output fan ratio. I would make the two on the front intake, and the back and side output.

In that case, make the two in the front intake, as well as the side. Your rear fan should stay as an output.

I'm not sure, it's not a brand I'm familiar with.

System specs? Budget?

From the look of the case, the front fan mounts probably wouldn't contribute to much airflow. You can probably get most of the same cooling with a side intake and a rear exhaust.
