Thermaltake Armor Fans, Replacement

Ya, so i'm building a "gaming" computer for myself...using the beastie case TT Armor case...with a 25cm side fan (http://www.newegg.com/Product/Product.asp?Item=N82E1681...)

In case your wondering, I'm using this, because I want a rock hard stable computer, and a big one with good cooling.

The TT Armor is huge so it has good airflow and seems to be very popular, but...

The case fans are notoriously loud, the 120mm ones are variable speed, but I've heard they usually run at top speed, which is like 48dBa, compared to tehre 17dBa advertised spped, thats way to loud for me, and I'm guessing (can't fine them on newegg seperate from the case) the 2 90mm fans are variable too, because they're rated at 19dBa. And then theres the iCage, I don't know what fan it uses, but its a 120mm blue led fan, but its not the same as the other 120mm blue fan.



So basically, I need to replace the 120mm rear exaust fan with a quiet one that pushes more then 30cfm of air (can be less). In my opinion the Scythe S-FLEX SFF21E 1200rpm is the best option, because it pushes quiet a bit of air, and is VERY quiet.

But thats only 1 fan, out of 4 (I don't need to replace the 250mm one)

Theres the iCages fan http://www.newegg.com/Product/Product.asp?Item=N82E1681...
which is rated at 17dBa, but i'm sort of sure that it rpm will increase and with it noise, but if I can't replace the iCages fan thats ok...


Then theres the 2 90mm fans in the top and in the back by the power suppy...and they are "rated" at 19dBa, but thats probably at the lowest rpm possible.... so I need to replace those.


So finally...to the questions

Can anyone figure out if the 2 90mm fans included in the TT Armor are variably speed, and how loud they are at top speed?

What are the most quiet 90mm fans out there that don't exceed the price of $20 each, and aren't to flashy with LEDs?

Any advice on fans for the case to help it keep quiet but still get good airflow?



Thanks, and I'm obviously new to this forum, I got referred here when my friend couldn't answer all my questions Smile and this looks like a good community and I hope to continue to be a part of it.

Thanks
