I'm just wondering, because case fans don't even make THAT big of a difference, in my experience; as long as they merely keep the air moving in a certain direction in your case, I don't think you can ask them to do much more.

The air circulation seems to be crap, as the GPU's running fine, and the CPU isn't too warm, though 47-54 C might be a bit much for some.

There isn't much into making a fan for a computer, so any model will work as long as you have the right size.

Both statements are incorrect.
Water cooling done properly will cost at least $150, if not more, just for a cpu loop; not all fans are perform equally: http://www.xtremesystems.org/forums/showthread.php?t=171661 ; http://www.xtremesystems.org/forums/showthread.php?t=137832

First statement was clearly sarcasm... but I forgot I'm on the intrawebs and I gotta make it painfully obvious of my sarcastic tones.
Secondly, a fan is a fan. You can design a fan to be more efficient than other fans or to be more quiet than other fans. Unless you have an extremely hardcore setup, fans don't matter so any mid range fan design gets the job done without spending $50-$100 on a freakin fan. A fan performs by how much air flow it can create and thereby having the ability to cool the heat sink better. Adding dBs to the mix is purely luxury vs the utility of a fan. Spending more money on having a slightly quieter PC is like buying an exhaust system that makes your car louder but not any faster. The links you showed had fans that showed CFM versus dB. The difference between the worst fan and the best fan at each CFM was only a difference in 5-10 dB. I'm sorry, but are you willing to pay more money for a high end fan or a mid range fan when the difference in dB at the same CFM is less than 5 dB?
To give you an idea, a 5 dB difference is only clearly noticeable of a change in sound level. 10 dB difference is twice as loud while 3 dB change is barely noticeable of a change.
So to restate what I said... and I mean restate. There is no significant difference between regular fans at your local computer store versus other more expensive fans. Cheap fans are just that, so you get what you pay for on the lower end... Unless you go water cooled, you will always have noise from your PC fans... OP, if you are really picky about 5-10 dB, by all means, spend your money the way you want. I'm just telling you it isn't worth it.
P.S. Seeing as how those links are 4 years old now, I thought I should add this. The largest difference in dB at the same CFM was around 13 dB difference between a San Ace 1011 and a Sunon 25mm. The San Ace 1011 is basically a cm bigger (at 38mm) while the Sunon 25mm has just that. The difference in price (back in 2007) was almost $15-$20. That much money for a measly 13 dB. To each their own I guess.

Depending on the CPU, 47-54 C idle is bad, 47-54 C under heavy load is only a tiny bit high but is well within reason and stability. If it's the former, get a new fan and heat sink... if it's the latter (and you still want to fix it), get a new fan and heat sink as well (no other real options). Case circulation is important, but if the fan isn't broken, a brand new fan won't be much help.
Lupin:
The OP should:
1. manage the cables.
2. make sure the number of intake fans are equal/greater than the number of outtake fans. More outtake fans will make your case a vacuum.
If you have a choice between 80mm and 120mm, pick the bigger one. It moves about the same amount of air with less rotations.

that's the probably normal idle temps for people living in the tropics (like me). Idle temps above 60 are what you should worry about.

What kind of an effect would that have on temperatures?
vuzedome:
Just screw in fans where ever possible in your case, then go get an after market bad ass CPU cooler.
