need some better but cheap case fans

Hello everybody
I have just build an pc again and the case i'm useing came with 4 fans its an zalman z9 plus. but the fans are quite noisy so i already took one out but the back fan is really loud but moves a lot of air away from my hyper 212 evo so i can't take it out so i'm looking to replace 2 or more fans in my case.
i just want them to move a good amount off air and be pretty cheap.

thanks anyway
 


what about artic f12 s? they are haf the price where i live and also would they do better then an stock hyper 212 fan?
 
The Artic CFM is is 10CFM less than the stock 212 fan. So less cooling.
They are rated well and quitter than the shark models. But they also move less air82.6 vs 74 CFM.
When my 212 fan died I replaced it with a shark model to achieve the same CFM rating and have been happy with its performance this past year.
I run two 460s and a 6 core processor 24/7/365 so cooling is a must and lots of airflow to remove heat from the video cards dumping in the case requires lots or flow.
The artic model would probably suffice for you as case fans, if dual video cards are not run at max 24/7. although I would probably stay with the stock 212 fan or a shark as a replacement.
 


thanks for the reply i will replace the stoch hyper 212 fan with an shark and the rest with some arctics because they are a lot cheaper (3€)
