Good airflow?

[senpepe]

Is this a good airflow system

The large 220mm intake fan on the side pannel of the case is what the larger blue arrow is You can see it on the fifth new egg image http://www.newegg.com/Product/Product.aspx?Item=N82E16811108228
the smaller blue is a fan http://www.frozencpu.com/products/2810/hdc-23/Evercool_525_Cross_Flow_System_Fan_-_Revision_2_-_PCAC2.html?tl=g34c147s299

the top rear exhaust is just a 120mm the one in the front of the case on the bottom is the same but only the lower half of that area in the case is vented Seems stupid for them to add a place for a 120mm but only half of it vented but they did.
The lower rear exhaust will be a pci slot fan http://www.frozencpu.com/products/10868/cpa-373/Lian_Li_BS-07_140mm_Fan_PCI_Graphics_Card_Cooler_-_Black_BS-07B.html?tl=g36c15s62#blank

Right above that pci slot fan is my gpu with a http://www.newegg.com/Product/Product.aspx?Item=N82E16835186048
This will be blowing right into the pci slot exhaust fan with only a one pci slot gape between them but im hoping it will help with the hot pocket of air i currently have with it and i could also find a pci slot fan that only takes up one slot instead of two so it will have two between them
Have a modular psu so i am good on cable management they are not in the way but i am planning to upgrade from my factory heatsink that might take up a good bit of space in a mid tower.

Here is my system specs.

Motherboard: M4A87TD EVO
Ram: Pareema 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333
Cpu:AMD Athlon II X3 455 Rana 3.3GHz
Gpu: Xfx Radeon Hd 4870 1 Gb Ddr5
Hdd:Western Digital Caviar Blue500GB 7200 RPM SATA 6.0Gb/s
Os: Windows 7 ultimate 64 bit
Case:inwin griffin yellow
Psu:OCZ ZT Series 550W Fully-Modular

Basically its, Front, bottom, Side for Intake & Top, Rear for Exhaust.

Doesn't that graphics cooler suck? And so does the pci slot cooler. The graphics cooler faces downards while the slot cooler faces upwards and so they would be competing for air. Bag the slot cooler.

the slot fans an exhaust fan

Yes. But the problem is that the gpu is sucking the air upwards and out to the sides while the slot fan is sucking downards and out back. So both objects are sucking air from the same area.

I believe that you are wanting the slot fan to take away the gpu's exhaust air. The slot fan is not an apropriate solution. Implementing the side fan is more appropriate since the gpu exhausts air out to the side towards the side of the case rather than downwards towards the slot fan.

So if you were to use the side fan to help your gpu you have to consider the positioning of the gpu and the side vent first. If the side fan faces underneath the card than I recommend having the side fan as intake to supply air towards the gpu fans and if the side fan faces the card or over it than I recommend haivng the side fan as exhaust so that it sucks away the air that comes out of the card. You want air flow to f-l-o-w.

But honestly side fan won't do much help in lowering gpu temp(neither will the slot fan).

No the gpu is blowing down its not sucking air with that cooler

I belive the gpu in fact sucks rather than blows. Looking at the fans closely they will rotate clock wise because the fins are facing that way. And if they do rotate clock wise they would suck rather than blow.

then i can just switch the exhaust under it to a intake.

The slot fan? I don't think any of this is necessary. Through personal experience, playing around with 100cfm fans in my case it made little to no difference. What was sufficient enough for me was a strong front intake and a strong rear top outtake. I played around with side fan but it only affect gpu temp by 1 degree. I have a lot of fans I can put in but they just made no difference other than more noise. The rule with airflow and cooling is that you want 'enough' airflow and remember that more airflow doesn't always mean lower temps.

Do you have all of this already? If you already do, than why not play around with the fans and see how it affects gpu temperature. Make sure you stress test your gpu while doing this. I bet that most of this won't be necessary.
