My case is raidmax cobra.

I have a total of 9 fans in my case.

Two coolermaster sickleflow led fans 120mm 1. Front (with mesh) 2. Rear Exhaust

Two Deepcool UF140 fans push pull on Deepcool Lucifer Tower cooler

2 Deepcool Iceblade 120mm fans top intake with mesh

3 Deepcool Windblade 120mm 1. inside the Drive Cage helping to pull air from the front. 2. One infront of the Graphics card which is like, it's hotglued onto the drive cage. 3. Bottom Intake with Mesh

Is this setup fine?

Temps idle 33-35, Load 40-50 (i5 4440)

GPU idle 35, Load 40-55 (Zotac GTX 770)

PS: I'm in a tropical country

Bottom line:
If the current temps, and the existing noise level, in the current setup, are OK....leave it.
Fretting over this fan v that fan, or specific placement of a particular model fan....does it work? Are you satisfied with the setup?

If so, leave it. or switch one around and see what happens. It may get better, it may get worse.
In such a congested case, it is near impossible to predict.

Your temps are nominal and good.

That said, I think you are over fanned.
Fans do not cool(A pc does not sweat).
Fans move air.
Fans are needed to get hot air out of your case.
A 4440 is not a hot chip and needs minimal cooling.

The gtx770 is more of an issue. The fan type cooler dumps the gpu hot air into your case.
Considering that gpu fans are in the 92mm size range, and you have two or three of them, you will want the equivalent amount of intake fan area to keep the gpu cooler fed with cooling air.
Two 120mm fans should be sufficient . Certainly three.

When you say front mesh, I assume you mean that the mesh is a washable filter.
That is good since intake air will be filtered, keeping your case cleaner.
But... do not use more exhaust fan capacity than intake or you will negate the positive pressure situation.
With more exhaust than intake, some air will be drawn in through unfiltered openings.

More fans add noise which you may not want.

The bottom line is that your cooling is fine but may be noisier than necessary.

it's not that noisy if i set the fans into quiet mode in the software my gigabyte motherboard comes with. i think it's called smartfan. about the exhaust top thing, i just followed the instructions in this guy's article http://www.overclock.net/t/1394467/ocn-daves-air-cooling-guide-updated, he said i should use top as intake and rear as the only exhaust. :(

@USAFRet. I also thought so, but in the article i read, i think he said otherwise. He pointed out that natural convection has minimal effects in a case with forced airflow. The air will go where you want it to go. In my case, i left the pci slots in the back uncovered because i have a fan inside my case blowing directly on the videocard sending the hot air through the open pci slots. Is this ok?

You can try it either way and see what happens. Me? I prefer to not buck the laws of physics.

At some point, you have to remove that hot air, rather than just blowing it around inside.
