Need help on choosing case fans

[Qyratar]

Hi! I wanted to bring down the overall temperatures in my rig, so I decided to install some fans in it!
The mobo is a Asus M4A88T-M 880G
and my tower is an "Ace Midtower Clubs IV Black" (originally came with a 450W PSU but I replaced it with a 750W)

What I have noticed is that I can put one 80mm both in the rear just under the PSU and I believe one in the lower front side.

1st pic is of the rear side and 2nd of the front side, the chip there makes me worried...

I Also believe that I can fit 2x 120mm side fans on one side of the tower which is located towards the upper rear side.

So I was planning on utilizing the 80mm fan in the bottom front and the 80mm fan on the upper back right under the PSU. (You're welcome to recommend me doing something else)

And so my actual question(s) is what good 80mm fan do you know of? I don't mind if it's a little loud as long its not as loud as a boeing.
And the other thing is, I have only one 3 pin connector. Should I get a 3 pin splitter or a molex to 4x 3 pin splitter? (2x +5V and 2x +12V)

I would appreciate any and all answers!

Tip: Bigger fan the better, more air = cooler pc
I would use the 120mm fan slots if I were you, and use the Corsair Air Series SP120 High Performance Edition.
But if you still want to use the 80mm, get the Scythe Kama-Flex SA0825FDB12L or if you can't get that the Sharkoon Silent Eagle 2000.

Edit: For the 3 pin question, get the 3 pin splitter, since a 3 pin has enough power to power two fans.

Should I then mount both of them as intake? or have the top one as exhaust and the lower one as intake?

Top one as exhaust and the lower one as intake.

After looking around for a while i found the Scythe 120mm Ultra Kaze Fan, 3000rpm, they provide double the cfm at a cheaper price, wouldn't this be a better choice? (considering that my CPU temp is at 72 C idle when the case is closed) Someone had the exact same temp problem as me (72C idle) and after installing two of those his/her CPU temp went down to 39C idle.
Or should I go with the Corsair Air Series SP120 High Performance Edition?

Go with the scythe ones then, since they're cheaper and the RPM looks good as well.
Good luck with the upgrade!
