Hello
My Specs are:
Intel Core i5 3470 3.20GHz
MSI B75MA-P45 Motherboard
8Gb Corsair Vengeance Ram (+3Gb of old DDR3 ram from my previous PC) (11Gb in total)
EVGA GTX 770 2Gb Superclocked acx version
OCZ OCZ-ZT650W Power Supply
Seagate Barracuda 2TB
Samsung 840 EVO 120GB SSD (Boot SSD)
SanDisk 64GB Pulse SSD
NZXT Source 210 USB 3.0 Mid Tower Chassis

My 2 questions are:
1) Are my GPU fans Intake or Outtake air? I want to put one extra case fan to intake air (from Outside) straight onto my GPU fans, to help cool it by giving extra air from outside the case. LINK TO MY GPU: http://www.scan.co.uk/products/2gb-evga-gtx-770-sc-acx-...

2) Is my Power supply fan do Intake or Outtake air? Right now PSU fan is facing the floor. (It has no space to exhaust the air or intake the air because its set on a carpet)(My case dont have feet) I've read that i can put my PSU fan facing the GPU (UP) if it INTAKES the air to help exhaust hot air through the back of the PSU. LINK TO PSU: http://www.amazon.co.uk/gp/product/B0068ODTZA/ref=oh_de...

Thanks.

1 Your GPU fans work inside the case (sucks in and blows out in the case) and therefore are not classified as intake/exhaust.
2 With bottom mounted PSU it is normal that it sucks air from the bottom and exhausts it out the back so not really intake/exhaust in that config. Apparently as your computer is placed you should turn it around having the fan facing up in the case making it as exhaust that way since it will be sucking from the case and blowing it out.
I do not know how many fans you case has but normally recommended minimum is 1 intake front and 1 exhaust back. If you turn your PSU with the fan facing up I would add min another intake fan either in the front (believe there is space for two) or on the side panel.

i have 3 Case fans. all of them are 120mm and all exhaust air i dont have any intake fan/ i have one just above CPU heat sink (top of case) and one on the back of the case there nearly touching each other. and one on the side panel just above psu and under GPU (in between psu and GPU) exhausting air. i dont know what to do because when i play games my GPU goes up to 80 degrees Celsius. thats the case i have and you can see all the fans on the THIRD picture and one extra on side panel. http://www.amazon.co.uk/gp/product/B005869J4O/ref=oh_de... i need some suggestion and help.

Ok top fan and back fan are correctly configured blowing out! The side fan needs to be blowing in giving fresh air to the GPU, I would either move one or the other top/back to the front or add a fan to the front. 80°C is warm but not to hot for a GPU that has a max temp in the mid to high 90's°C.

Thank you very much. I will change the side fan to blow air "IN" and buy additional fan and put it at the front.(BTW when i add front fan should it be intake or exhaust?) and should i change my PSU orientation?, are you sure that my PSU is "sucking" air in and exhausting at the back?

Front Intake! All modern PSU's with big fans suck with the fan and then vent through the perforations in the back. Older PSU's with as small fan on the back actually sucked air from the outside ant vented the heat from the PSU inside the case!

Ok Thank for help. i Just changed my side panel to intake and i ordered corsair series fans on amazon and i will put them in the front to intake air. Also one more question, i just checked and i can fit a fan in the front but it will be touching the inside of the front panel and the HDD cage, where is it going to take air from? there are fan holes (like in side panel) But straight of that is the front panel check the link and image. "second image" and look at the front. i can fit a fan inside but where isit gonna get air from when theres a whole aluminum plate with no holes.

Thank you, you helped alot, sorry for being a pain in the ass, just wanted to know everything. Also is it worth putting a dust filter on the intake on the side panel? or top/back? and i bought 2 fan filters but they cant be mounted to anything, do i mount it outside or inside? http://www.maplin.co.uk/p/12cm-air-filter-for-fans-a40g... its so fat and i cant figure it out.

Normally filters would be between the fan and the mounting place on an intake fan, no need on exhaust fan.
