Best air flow for Corsair 300R

[Cruncx]

Hi guys, I`m about to make a new pc...
And it`ll have the following hardware:
2x4GB corsair 1600 MHZ
ATX 800W REAL CORSAIR GAMING GS
ASUS P8Z77-V LE
i5 3570
2TB HDD seagate barracuda green
GTX 670 or RADEON 7970 - still deciding

And i`ll use the Corsair 300R case...

What I would like to know is:
What`s the best fan configuration on it to have the best cooling it can achieve?


Thx!!

Do the usual. Front and bottom intakes, top and back exhaust. Sides could be intake or exhausts, doesn't really matter. Just keep in mind that more airflow = more dust, so just add fans only if you need to.

Hmm, got it!
Any other hints?

Corsair 300R have very few dust filters.
So,even if we use only two fan can we able stop dust and keen system cool ?
I mean if there is only intake at front bottom and an exhaust at rear.
And do nothing about rest of place(big mesh gaps at fan slots at side and top) where there is no dust filters.

As long as there is airflow, you cannot stop dust, even with filtered intakes. With my setup of filtered intakes, I only managed to reduce the amount of dust but never stop it completely.

You are pressurizing the case by blowing in air, you create a positive pressure. The air that is blown in has to escape somewhere and there will be a slight outward draft passing through these empty slots. As long as there is air exiting the case through these holes, dust will not go in and I don't see the need for filtered exhausts or filtered empty slots.

You didn't ask, but as to your proposed parts, that hard drive is not optimal as a main drive. It's quite slow, and given the level of other components you're using, it's not the right choice.

Thanks for reply!
Will positive pressure gonna increase huge amount of system temp or its negligible ?
If we can't spot dust completely then we need a case which can be clean very easily and quickly.
Thought its only my thought.
I'm gonna buy a new case soon or later so I will keep these point in my mind.
My situation is little different from other.
I don't have AC in my room and air full of dust cos of air pollution.
And then high temp(35C-45C mot of the year) and humidity.
BTW,humidity have any effect of PC temp ?

Positive pressure is just a method of moving air, it is just one of many. It depends entirely on how your rig is configured, it may or may not benefit you. Anyway you decide to orientate your fans, the difference is minimal. Whats more important is that cool air goes in and hot air goes out.

Humidity under normal circumstances will not affect your PC. Its just that your idle will never go lower than your ambient temps unless you're using cooling methods that are beyond normal watercooling.

I agree with the above comments. Start off with bottom and front intakes, rear and top exhaust, block side port and evolve from there if need be. Align CPU cooler with top/rear exhaust. Add dust filters for all intakes. Makes sure you have a slightly higher pressure in the case than outside. Use large PWM fans and run them as slowly as you can using fan profiles linked to CPU or GPU temps for reduced noise. And other obvious things, such as do not put the case in direct sunlight in Summer.

You can do without the 120mm on top and 1x 120mm in front. The reason why I used so many fans was because I was housing a GTX 480.
