Best way to improve air circulation in my case?

Hello!
So I bought MSI R9 290 Gaming some time ago, it's quieter than reference R9 but still not quiet enough, so before I'll change the cooler to something better first I want to try to improve air circulation instead. So, below Is shown how it looks now (case's Silencio 352).

So, I think of buying 2 x 120mm fans for intake (front) and a 140mm exhaust fan. What do you guys think? I don't know what fans should I get although Aerocool Dead Silence look interesting.
Important notes:
1. The PC is in specific position so it has only 10 cm distance to shelf (on the top) and about 7cm to the wall (on the rear).
2. I have dismounted the bottom disk cage so it doesn't obstruc airflow.
3. I have the intake mounted on the bottom of the front (on picture is on the top of the front).

warm air goes higher if he put top for intake then all the warm air whould stay in the case giving him poor temp results

I'd say go for 2 intake fans in the front, 1 rear exhaust and 2 top exhaust. That way you have more fans pulling air out of the case stopping hot air lingering about.

With regard to what fans that really depends on just how quiet you want them. I have a mixture of be quiet! and Noctua fans. The be quiet! fans are VERY quiet but louder fans will provide more airflow. It's all about finding the right balance for you.

On a side not, make sure all your cables have been tidied so they don't obstruct air flow movement around your case.

EDIT: What Jovan says is spot on, don't have top fans as intakes! Hot air rises, don't work against it.

The back fan is at the top too, it's not at the bottom, it's always better to have front and top as intake and only back as exhaust

You are 100% wrong, you ALWAYS have the back and top as exhaust and the front, bottom, side as intake.

I don't really mind relatively loud fans because they're still going to be much quieter than the GPU. Also do you know any good (pref. white) fans that don't cost a fortune? How about the Aerocool DS? They seem to be pretty cool.

Then you're working against the basic principle that hot air rises. That would also mean there would be positive air pressure in the case causing hot air to move around the case.

General rule of thumb is to have more exhaust fans than intake, that was air doesn't get stuck inside the case and raise temperatures.

For my own PC I have 2 140mm intakes in the front, 1 120mm bottom intake, 1 120mm exhaust at the back and 3 140mm exhausts on top.

this is how i solved my problem with front fan case is CM HAF 912+

https://scontent-b-vie.xx.fbcdn.net/hphotos-xpa1/l/t31.0-8/p600x600/10515328_492949740838169_2635575035988079520_o.jpg

i just placed one CM SickleFlow airflow fan behind 200mm megaflow also from CM to scoop the air coming inside the case couse that 200mm fan was pushing only downwards now and it was blocked by SSD and HDD now its going downwards cooling HDD and SSD and that sickleflow is blowing in middle of the case on a hot day my GPU dont go above 68c and cpu does not go above 56c while gaming

The go-to fans for many PC builders are Noctua's they provide a VERY good balance between cooling and noise. I looked at the Aerocool DS and on the spec sheet they are very similar to certain Noctua's in both cooling and noise. Although I'd always recommend reading the specs from manufacturers with a pinch of salt those Aerocool DS fans do look good.

Go for them, and order from a retailer like Amazon, then if you aren't happy with them return them.

You have a very nice case that is optimized for quiet, not so much for cooling.
I would move the rear 120mm fan to the front as intake. Try that first.
There is normally little advantage to more fans since the intake air provided by two 120mm fans should be all the cooling air you need for your cpu and graphics card.
To get an idea of the max potential from more cooling fans, take the covers off and see what that does for you.
The problem with the R9 aftermarket coolers is that they do not dispose of the heat from your case well.
Stock blower type coolers are better at that. R9 cards are overclocked and do generate more heat.
That said, graphics cards and cpu's are built to tolerate heat. They will slow down or shut off to prevent damage. How much do you really need to reduce temperatures?
Adding more fans and stronger fans(high rpm) will add cost and noise.
If you do add fans, prefer 140mm over 120mm; they run slower and quieter. I like the noctua fans which are of the highest quality.

You always want the rear, and top to be the exhaust fans. They don't have any dust filters, so more dust will come in. + With hot air, it'll rise, and the fans on top and rear will exhaust it.

Always have the fans that are situated the lowest relative to the ground/ base of the computer system as intake and the fan or fans highest off the floor as exhaust fans. Why? Remember this; hot air rises while cold air falls. When the computer intakes cold air that would be at the lover lever, as it cools the system inside , this air becomes hot and rises to the roof of the Computer tower- thus, if the exhaust fans are situated at the highest point, the hot air will be expelled much easier --- this makes your system far cooler.
Based on the labeling of your system in the image you have there,the bottom fan is ideally placed , as well as the exhaust fan. The other is still at a lower level than the exhaust fan, so that is ok also.
As for the fans I would recommend getting two Cooler Master Sleeve Bearing 120mm Silent Fan for the front and a Noctua 140mm Premium Quiet Quality Case Cooling Fan for the exhaust.
