Possible bad airflow case, need help on airflow scheme.

[Tacca]

Hello,

 

I would like to ask some help about how to configure the fans of the case I bought in a proper way.

The case I bought is this one: (Bluecase BG-015 white)

 

Now, the front fans have clearly low space for the 2x120mm fans to intake a good amount of air in order to have a positive or even neutral airflow.

So, my thoughts, even knowing the hot air tends to rise up, but, I thought about putting the 2 top fans as intake along with the 2 front fans,

and for exaustion I would use the rear fan and put a small one below the GPU, maybe a 80mm will fit.

 

I thought about that because I have an air conditioner on the top of my wall, so a lot of cold air is being thrown downwards, which then would reach the top intake fans.

 

What do you guys think?

Ah, and of course, I will think about a way of filtering the dust of the front intake fans.

the top fans already comes with a nice magnetic filter.

 

Thank you in advance.

Air your doing a tower cooler or aio?

Hahaha, stock cooler, wraith prism, Ryzen 7 2700x, and a MSI RX 580.

The top should be exhaust.

Get static pressure fans for the front. There is a restricted intake and behind the fans is a cage.

Top fans should probably be exhaust not intake. Rx580s can be warm.

Thank you, I went searching for these fans around here (Brazil) and found pratically nothing.

The only one I found more was a pack with 3 CoolerMaster HD120, which costs more than double the price of the case I bought...

I will run some tests when all my normal fans arrive, if it turns out to be too hot, I probably better getting a new case (with good front airflow) and using the normal fans I bought.

 

Thank you.

If you post some stores which are available in your area, we can check what would be best fan for you.

My other 3 fans arrived along with the fan controller.

Before, I was running just two 120mm fan, 1 top for exaustion and the rear fan as intake... (pretty bad scheme tbh)

The temperature playing Dauntless on maxed graphics was reaching 85~90c... so I was worried.

Now, I installed with the scheme I mentioned, 2 top fans as intake, 2 front as intake, and rear fan as exaust...

The temperature now is between 65c~80c... Pretty nice tbh, I will stay like this.

 

I understand that the top fans should be exaust, since the warm air tends to go up, but,

Why this cheap case creators placed a dust filter on the top fans then? hahaha

 

Thank you all.

What fans did you get?

it looks nice

A top filter can be used to reduce the amount of dust settling into the case and allows for the option to use the top as intake without letting in unfiltered air.

Indeed, when it's off, dust can fall there... Now I am looking for some kinda of mesh, to make a custom dust filter for the front intakes...

Worst case scenario, I will just cut my woman's pantyhose...

 

Hahaha

In a computer case with fans moving/forcing the air, there are really none thermal rising of hot air as it is pushed out with the airflow front to back. And top fans didn't became mainstream before AIO:s and watercooling became mainstream. If you don't have a top mounted radiator the point of having top mounted fans is gone. It cause more turbulence and disturb the desired path of airflow from front/bottom to back. Plus that the perforated top makes it harder to have a controlled pathway as the law of nature (and mankind) is to take the shortest path possible so the back fan sucks air in from the top and out the back instead of pulling air from the inside of the case, likewise for the CPU-cooler. So without a dust-filter you suck more unfiltered air in though the top instead of the filtered inlets in the front and bottom of the case.

 

There is a reason server-chassis  don't have mesh as the key to cooling is to control the airflow from front to back.
