Fans - Too many? Too Crowded? Too Unsecure?

Hey guys building a new system:

Thermaltake case:
http://www.thermaltakeusa.com/Product.aspx?C=1468&ID=20...

with a M5A97 MOBO
AMD FX 8120
8GB Corsair Ram


BECAUSE of all the stuff in the mid case, I am have a slight crowding issue when it comes to fans. I am using 3 Sickleflow 120 2000RPM fans:

http://www.coolermaster.com/product.php?product_id=4375

So this is the way I have the fans:

http://rmtphotography.com/case.jpg

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?

Help?

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

How about the front fan Exhausting, and the top and side fans coming in? I compute in a warm enviroment (Florida and the air is about 78 degrees INSIDE at times)

Heat rises, best to keep the top fan as exhaust. Front fans are typically lower, that's why they're placed as intake. Side fans as intake are fine as well.
