Cases for on board graphics

[decimusbell]

Hi all,

This might sound like an odd question, but i was thinking about the air flow in cases, especially in regards to PC builds using on-board graphics. 

 

Basically my thought was that for a case to cool efficiently the direction and flow of air needs to be specifically funnelled and directed. I appreciate that cases have all sorts of vents, holes and areas where air is allowed to escape, but cant these be counter to the cooling you are adding and the general noise produced by the PC itself. e.g. air is allowed to escape using a method counter to the cooling the user has added. 

If you don't happen to use a graphics card, then surely the area where the ports are negatively affect the direction and streamlining of air flow and leave a space open for noise to escape?

Ideally i would like my new build to be as silent as possible, so all these areas should surely be covered. 

So my question is two-fold. 

1- am i right in thinking that all the areas for air to escape on a case for example on the rear of a case adds to the overall inefficiency of cooling generally and lead to added noise.i.e. shouldn't a case fan act like a turbine sucking in all the hot air around and pushing it through 1 route?

2- are there cases available where the aim is to directly channel all airflow using the cooling a users adds, and more specifically, cases available designed for no graphics card use- as i am a user looking at a new build which will using on-board graphics in small form factor. 

 

As i say i might be completely wrong about all of this- just would like some advise. 

 

Kind regards

If you're using the iGPU, there's little chance the pc will generate enough heat to ramp up the fans to audible levels.

fractal design meshify c has loads of ventalation as the entire front panel is mesh and a large top panel opening with a magnetic mesh covering aswell.

there is also a m-atx version in the meshify c mini

AGREED, however surely therefore there should be cases where there is 1 route in and 1 route out for airflow. bring down the size and noise created.

It's often better to design a case with vent holes to allow for air to escape than to design the case with only one intake and one exhaust and seal the rest of the case. 

 

not even be quiet! does this; a company KNOWN for minimizing vents in the name of silence
