Is it really a difference

i am think to buy some fans for my cases i am prepared to buy up to €20 euros for each fan i would like to install at least 2 fans but if it really makes a diffrents even 4 fans in my case.

 

i was thinking about buying the corsair air series AF140 Quiet edition but then i saw the Air Series AF140 LED Quiet Edition and those were even cheaper but a bit louder and a littel bit less air flowe and does 1,5 dBA make a huge differents because if i am gaming my video card is most of the time around 70 % fan speed but still if i am not gaming i would like to have quite case.

If you want quiet, buy Noctua.

cougar fans are pretty cool. prolimatech just came out with some really cool thin style fans.
