Need to know the Best setup for 3 Case Fans for less dust and more cooling?

[_Whitedragon_]

Hello friends,

So far I was using the 2 stock fans that came with my case (Corsair 300R)....but now I bought a gtx 1070 and also 1 more case fan (Cooler Master Sickleflow) since I thought adding a GPU will result in more heating..so now I have 3 fans for my case...I want a positive air pressure in my case so that there is less dust and good cooling in my system...Can you guys tell me how I should setup all 3 fans to achieve this?

I would do two front intake and one rear exhaust. For positive pressure you want more air being brought in than is being exhausted.

Depends on where the fans are. If they are on the top of the case, exhaust. but if they are on the lower half in the front (around drive cages and such) intake. If you put intake fans at the top you are more likely to be blowing dust directly into your case.

I have the Corsair 750D Airflow and I have a 5 fan setup, 2 intake (in the front of the case in the lower half, 1 exhaust at the top rear, and 2 blowing exhaust through a 280mm radiator from my cpu cooler.

Also if you don't have a grille in the front and just a panel I would try to find a way to open it up, otherwise you will be circulating warmer air into your system than cooler ambient air from outside your case.

I have a grille in the front and it has mesh attached behind the grille which I cant remove...currently I have one front intake fan just above the hard drive cage so the fan can blow air directly to the GPU when I put the GPU in and I have a rear exhaust fan...should place the third fan in the front for intake or place it at the top for exhaust or on the side for intake though I don't want to place it on the side since I think it will block my view of the GPU?? which is the better option??

I would put it in the front. You can always get two more fans to put at the top of your case, which I would recommend for optimum airflow, or to decrese hot air in the case, get an AIO liquid cooler.

Thanx for the advice and yes I will be buying maybe 1 or 2 fans in a month or so meanwhile I will have to do with 3 fans...putting the third fan in the front for intake will create positive pressure in my case which means less dust, right??

It should.

It should.

Thank you for the help!!!
