My case is the azza armour 203, and i have a nzxt sentry 2 fan controller. I have a blue led side inlet fan and two outlet red silent fan with my water cooling system. My core temps are around 30-35 on standby and at load the most i have seen is low 50's. But my GPU sometimes gets to very low 80's.

My main question however is should i add another fan by the harddrives or on the top of the case, so it creates a positive pressure inside the case. My temps are fine, just want to make sure my system lasts as long as possible.

to me it seems the GPU is the main concern here, is it connected to your water loop? You haven't stated an exhaust fan only outlets for your radiator. So I'm thinking, if the GPU is connected to the water loops, it exhausted hot air and the hot air has nowhere to go because of the lack of an exhaust fan. I'd reccomend putting 2x 120mm exhaust fans on the top.

So basically yeah add fans to the top of the case

My GPU is not in the water loop, however in most games the temp is around 60. I think that 80 was just a really hot day or something. But i think it is because im running a 550ti at high settings. (Soon I'm getting a 760 =P... YAY! )
My video card is upside down (fans facing downward), would this affect where the fan placement should be?
My Cpu cooling system has an intake above the video card and an outlet in the top back of the case.
Would it be a bad idea to have two exhaust fans (the two fans you suggested) and only one intake (side fan), since i heard about how you should have positive pressure in the case.

since it's facing down I'll make an assumption.. do you have a bottom PSU case? if so have it facing down so the air exhausted from the PSU doesn't interrupt airflow and the hot air is exhausted out the bottom of the case, the GPU facing down will exhaust its air towards the same vents as the PSU.

Like I said before make sure you have an exhaust fan preferably in the back. Yeah more intake than exhaust is a good idea to have positive pressure, the exhaust fan should be put a fan controller so you can increase/lower the RPM as needed to keep a nice positive pressure. If I were you I'd just put an exhaust in the back and maybe add another another intake on the side or front. hook up the back exhaust fan to a fan controller preferably. Maybe a picture of your rig would suffice and arrows on each fan pointing the direction they blow. Then I can give you more information and maybe a better config
