cooling for cpu top

So i have a rig with the following specs :

i7 7700

gtx 1080 asus strix 8gb

16gb 2400mhz ram

750 watts psu

 

these are in a circle cc830 cabinet which comes with 3 fans (each of 1000 rpm). one at the rear part to take the warm air out of the cabinet and two at the front to put cool air into the cabinet. now there are two outlets at the top and i have two 2400 rpm fans so i should install them at the top in such a way to pull cool air inside the case or to pull the warm air outside ?

because there are already two fans to get cool air into the cabinet and only one to get the air out. Please suggest me how i should install these two fans.

Moved to air cooling section. 

 

For ideal cooling, you want to have neutral or slightly positive air pressure inside your case. Having slightly negative is not necessarily a bad thing, but it can cause quicker dust accumulation inside. You also want to keep the airflow inside your case all flowing consistently and uniformly in the same direction (typically in the front/bottom and out the rear/top). IMO, having uniform flow is more important than worrying about the pressure.  

 

That being said, I would definitely put the top fans as exhausts, so that you have nice, consistent flow moving in the front and our the rear/top. 

 

However, you are not stuck running those fans at those fixed rpms. You can control the speed of all the fans, if you so choose. In doing so, you can also control the interior pressure. If you run them on the motherboard fan headers, you can control each header independently. This will allow you to run the front fans a little faster and the exhaust fans a little slower to create nice neutral air pressure and still have good flow for ideal cooling. ;) 

 

What fans are you running and what motherboard do you have?

No prob. 

 

So yeah, you've got 3 extra fan headers on that board (not including the CPU header). If you want, you can run your fans off of those (with splitters if need be) and control their speed through the UEFI/BIOS or with various software programs.
