New Build, PSU Intake fans and GPU intake fans work against each other?

[Tyk3]

Hi guys,

I am planning to build my new system in coming few days. I planned to go with a Corsair GS 600W PSU which comes with a blue LED fan. so naturally i want to keep the fan inside the case to use the glow for some bling. I am going for Cooler Master N200 case with side window.

Now here is the issue. In this setup, My GPU (ASUS Direct CU 2 cooler) will be right above the PSU Intake fan and GPU Fans will compete against the PSU fans for intake air. Which is not very optimal air flow setup. PSU fans sucks in air and blows it out from behind the PSU, GPU fun suck in air and blow it on top of GPU.

I want to know if anyone else is using this type of setup and if they can tell me does it really affects the tempratures.

Any help is appreiciated, thanks.

so long as you have cool air entering from teh front or side [facing teh Card] you should have enough airlfow. I suggest running a top or back fan ata high speed to suck warm air out the back or top

Turn your PSU with fan down if you have bottom ventilation slot and buy LED strip for your case, it will give much better light inside the case then one LED fan.

I wouldn't worry about it.

if they are more than an inch apart dont worry about it, if they are closeer than 1in, turn the psu upsideodwn and make sure the case is avobe the floor surface

Thanks for the suggestions everyone, LED Strips are rarely available in india and where they are available they cost an arm and leg. So doesn't maskes much sense to spend on them.
I did some personal research and apparently those two fans working against each other create a very low pressure area in between PSU and GPU, so if there are high flow fans sucking air inside from the front, that cool air goes straight there, and things work ok. So it is cool, shouldn't be an issue , i will post temps once i have assembled the rig. Cheers!

It doesn't matter, gpu's don't push the cfm that hard, they are working to push air through the dense heatsink fins so not that much air is really pushed through, its certainly not a vac situation working against the psu, which also is low flow, just have enough intake vents or fans and the air both are working with will be cool enough that it doesn't matter.

If anything it might be good to have the psu exhaust much of that hot air off the gpu almost immediately, that gpu has fans just blowing straight down over the heatsink...the air exhausts all around the card and then would be extracted by the psu.
