if the RAM and the video cards are parallel instead of perpendicular

Thank you for your answer , I think is not a problem to reverse the direction of the airflow inside the PSU , the amount of airflow must be for this PC Power & Cooling 910W PSU about 30 to 50 CFM , no matter which way the airflow move ( backwards or forwards ) , the cooling effect inside the PSU is the same


I am choosing which fan to attach to this PSU , the original fan was not total silent , I have found a really silent ( at low-middle speed ) Silverstone thermistor three blades fan , developing between 20 to 73 CFM

Sorry I made a mistake, " the cooling effect inside the PSU "is NOT the same , because the traditional use of the PSU to take out from the computer the hot air developed/produced by all the other components is not really the best design , I reversed the airflow inside the PSU to take into the PSU just fresh air from outside the case ,my PSU will be installed vertically , therefore the low amount of heat developed by this 80 Plus Silver PSU , will escape toward the roof of the case sucked out by the two 140mm exhaust fans installed on the roof

No, what you are doing is pushing warm air into the PC case. Its fine to say it is efficient, but it still produces heat. Why change the airflow around at all? I do not see the logic . . . .

And to people meantioning BTX. It started, and died a death! I doubt it will rear its head again.

Also your CPU heatsink develop heat and the warm air produced by your CPU heatsink is constantly pushed inside your case , do you permit to your CPU cooler to push warm air inside your computer ?

No, since the fan direction of my components ensures that all the hot air is vented as soon as possible. The PSU is on the bottom and sucks the air out that is missed from the graphics card (Which also vents its own warm air).

The CPU HSF warms its air and is immediately vented out the rear via a fan.

Minimal air circulates inside the case. It even has a top intake (Cools better then having it s an outtake).

And what do you think is the problem to direct all the heat of the : CPU , GPU and PSU toward the roof of my case to become sucked out by the two 140mm exhaust fans installed on the roof of my case ?
