More intake or more exhaust fans

[Jaspreet_816]

I have built a custom made pc case . Which has 4 case fans space 1 at back 2 at left side and 1 at right side but on right side there is also the fan of PSU and on left one is used as exhaust of graphic card air. So what should i do
1. Place intake and exhaust fan side by side
2. Or install 3 intake and 1 exhaust fans.


Note:- on left side one is exhaust and other is intake. On right side one is PSU fan and other intake. Back is CPU exhaust


Any help would help Thank you

My case has 3 intakes and 1 exhaust so I am probably biased, but positive pressure beats negative when it comes to keeping dust out. I am no expert though, I just like the idea of not having to clean PC as often. IT also keeps PC cool which is always nice.

I assume intakes are filtered or it won't keep dust out.

Means will i be able to play high end games. And if you open case after playing games then the air will cold, hot or warm inside case. And will positive pressure saves components from heating

The aim of positive pressure is to have more air being sucked in than out so that it blows hot air out of case in the rush to escape. It blows air out of anywhere it can escape and keeps pc cool, it doesn't let heat build up in any areas provided case cables are tidy and not in way of airflow. - its main reason I chose my case.

If you have more exhausts than intakes, it means all the air/dust tries to get into case through all the gaps in case which aren't filtered and you would need to clean PC more. also may not blow heat out as well.

Thanks for helping me. I will use more intake so that it will release heat and make my pc cool and heatless. Thx man thx for helping. But can i install intake fan in front of graphic card's exhaust is it perfect

can you show a screen shot of your case where gpu is?

I have to remember not all cases are designed like mine:

the red thing is the GPU, motherboard rotated so heat blows out top of case. 3 intakes at base of case

Its not built completely. Its incomplete. But i can tell you that graphic card has 1 fan and just in front of that fan a case fan is installed. There is 3-4 cm difference case fan and graphic heat sink. So that case fan should also be exhaust or intake. And one exhaust is just side to cpu heat sink. So it suck out cpu heat

i would have fan infront of the GPU as an inlet as by having more intake create a stream of air that wants to leave case, and to blow hot air away from GPU. You should onlyu need the one outtake and the one near CPU is best place for it. As long as Air can escape other vents as well it should be okay

You want more intakes than out and even some GPU can act as outtakes so counting all fans helps or it won't work (Can ignore CPU fan). I make mistake of running my GPU fan constantly in summer and that disturbs the balance of airflow in my case - I should know better, the dust on vents should have been a clue.

You mean to say that i should install intake in front of graphic card so it make pressure in it and throws out the hot air from the exhaust fan placed side of the cpu cooler and also release cpu and gpu heat. Yes or No

 

[Colif]

that sounds about right. This front fan, is it at front of case or on a side wall?

if you have way more intake than out, the added air blows itself out of case without as much need for an exhaust. YOu still need one for when its really hot in PC but generally all the inlets act as exhausts
