Sounds good. The room where I have my pc can hit 40c... I love Aussie summers (not).

+1 filters. You will be surprise how much dust you will have after a couple of months, Its not so much dust in the case, its the dust that gets trapped in the rad and decreases it cooling efficiency.

The answer is: It depends

With a case set up for significant positive pressure, exhaust will do well. Another reason for going exhaust is that you *may* (sometimes) end up getting good airflow past otherwise neglected (but still important) heatsinks.

Look at your case, look at the fans you have available, and try and guess how the air will flow in there. I admit this is a little tricky when it comes to any case other than the Silverstone FT/RV series which have a definite airflow path, but it can still be done.

The idea is positive pressure with all intakes filtered (where more fan power is pushing air in, than out).

Filters are definitely starting to sound like a good investment then, I need to get higher static pressure fans though I have a ton of CM R4s over here but afaik they're better as case fans rather than rad fans.

So I also need to aim for more positive pressure than negative gotcha

I think I got the bottom part covered I have a 120mm blowing air directly into the video card (couldn't afford a water block for it this time but will eventually ) and the other fans on top of the hdd cage are blowing straight into the ram/NB/socket area.

With the case i have it really does not matter, as long as you have that back fan exhausting air it all works, right now i actually don't have an exhaust fan, my exhaust fan is the two 75 CFM fans on my 212+, as long as you don't mind a ton of dust and actually having to clean your case out monthly or more often intake is great, if you really don't want to deal with that, get some dust filters and run exhaust, it all depends on the case.

Positive air pressure is best, with the proper intakes of course.
Always go bottom to top on airflow..
Good luck.

That one looks better right? I forgot here's a pic of the 120mm fan blowing air into the mobo: So my guess is that one will blow the rad's exhaust into the rear 120mm fan right?

Yes, that looks fine.

Paint is underestimated
