Air Flow

[Radec]

Whats the best air flow for a case? Making the fans blow the air out of the case or in?

[crunzaty]

Well both, I would recommend getting the intakes at the lowest point and then having the fans on the higher lever be out-takes :)

I use my side-window and front fan for intake and the rad and back fan for out-takes so i get a good as a airflow as possible ;D

You want to have positive air pressure in your case so that means having fans blow air into the case and air out of the case. You should have more intake fans than exhausting fans so that there is a less build of dust in your case.

they forgot to say filtered intake fans..

 

the positive pressure will exhaust naturally though openings you might not have

known about. if you were running a negative pressure scenario, those same

openings are now intakes with no filtering and now you have a colony of..

dust-bunnies..

To have optimal performance, you will have to have both in-takes and exhaust to create a positive pressure inside your case. I recommend that you have the in-takes at the lowest points and the exhaust at the highest because according to basic science, cold air goes to the bottom and hot air rises.

to have uptimal cooling i would say have the PSU intaking from out side of the case so it is its own cooling system, have the bottom fans as intakes and front fans as intakes WITH DUST FILTERS, the top and back as exhausts and any large tower cooler having the air flow going up if your case has the holes in the top if it does not have the air flow to the back. If you are watercooling you should have any and all Rads intaking air for optimal cooling in pull or push/pull becuase the rad will act as a dust filter although you will have to clean the rad along with the dust filters. and make sure all intakes have a dust filter on it and nothing is obstructing the airflow in, out, or through your case, so keep your wireing in the main chaimber very neat and also if you have fans on the bottom like the PSU or other intake fans keep it off of carpet and raised up enough to get as much air as it can.

 

EDIT: make sure you use the correct fans for the job you need them too!!!! pressure optimised for rads HDD cages and bottom of case. Airflow optimised for open spaces like the back or side of a case or in the front if there are no HDD cages in fron of them. so if something obstrucks the airflow then use pressure optimised fans if there is plenty of room for the fans to breath then use airflow optimised fans

The norm is to take in air from the front, side, and bottom, and exhaust air through the top and rear.  And PSU goes fan down if the case has holes for the PSU fan to intake air.

 

You generally want more intakes than exhausts (positive pressure) but it's difficult because pretty much every case has top and rear exhausts, but very few have bottom and/or side intakes.

 

That being said, these guidelines aren't set in stone.  If your radiator intakes air from the rear and that works for you, then go for it.

 

Most GPU coolers blow air all over the place and screw up your airflow anyway, so it's not worth worrying too much about. :lol:

You want the air to go in from one side of the case, and all go out the other side. A lot of people use the fronts as intakes, and take the heat out from the back.
