Cooling Case

[KByte]

So , i wanna know how would it be best to install fans and power supply into case .
I wanna know on what side i would install power supply , either it'll get air from case or from outside of the case.
And fans  , i'll buy Corsair 200R case , and i'll get two Corsair FAN , AF140 , LOW NOISE HIGH AIRFLOW fans . 
So i wanna know where do i install them if i'll have 2 stock ones

If you have 2 fans total you always put one in front as the intake and one in the back as the outtake so you have a constant flow of air throughout the case.

For the psu a lot of times is a personal choice. It's only necessary to install with the fan up, intaking from the system, if you're running the case on carpet or there is something blocking the intake. Vise versa, if you have a high-end non reference gpu blowing hot air around the bottom of your case it would be better to have the psu intake facing down. Hope this helps.
