Will this make some cooling problems?

[AltairBG]

Hello!
I dont know if this is the right place to ask (and sorry for my bad English) but i made my custom build gaming PC and the PC box have some holes at the top..They are for future use of fans there but for now i have fans only at the front of my box and at the back + my CPU fan and 3 fans for the video card + PSU fan.
I will insert 2 photos to let you guys see what i made to prevent the dust to go inside the computer box.Will this cause some problems with the cooling or no? Because for now when i go near the holes i dont feel some air to go inside or outside.

You can cover those top fan mounts if you like. Some cases don't even have them- just a solid top.

if you have no fans on that spot, then you don't have problems, but that is the best spot to have fans on the system.

Soon i will buy fans or atleast water cooler and mount it there..But for now..When i start to clear the dust at the top..the half of the dust drops inside the computer :/ so this wont cause any cooling problems for now?

no

without knowing your fan layout i can't say for sure, but you should be good. With the fan at the back of the case the case airflow should be good. with one at the front (two would be better for positive air pressure). So what you are doing is fine.

Hope this helps

If you're worried about dust, you can get generic after-market dust filters for fans (either magnetic or with screw-holes) off Amazon, etc, and fit them ...
