I have ONE in the front (unsecured, more on that later) that is flowing INWARD (blue in the chart)
I have ONE on TOP (crowded, more on that later) also flowing INWARD (blue in the chart)
and I have one on the SIDE of the case, ALSO flowing INWARD (blue in the chart)
The case came with an exhaust fan, flowing OUt (GREEN in the chart)
The Power Supply ALSO has an exhaust fan, flowing OUT (GREEN in the chart (bottom))
SO the issue is this:
1. Are 3 inward and 2 outflow enough?
2. the TOP fan is ALMOST touching the memory and CPU fan/heatsink. Is that OK?
3. The FRONT fan is not screwed into anything and literally just sitting in the front of the CASE. It cannot get anywhere because the harddrive is in it's way of floating if I happened to tip the computer, but is that OK?
your worrying too much about heat ! try just use the front fan blowing in on a low speed setting the top fan exhausting and the rear fan exhausting leave the side air vent pul in naturally .
cooling is normally better under negative pressure and buy a good cooler for your cpu not just the stock cooler that comes with it
