can i use 3-4 8omm case fans in my cabinet which is having frontech 450w smps?Is there any 80mm case fan which makes less noise,i bought two zebronics 80mm fans but it makes a lot of noise or is there any way to reduce its noise?thank you.
case fans
120mm case fans make less noise since they rotate slower than 80mm. But you can't really do anything about noise. Get a good psu. Your psu is considered scrap metal here 
Even i had the same psu and it went kaput along with my motherboard. Better invest in a good psu. Your current psu will not last long with 4 case fans.

@OP - difficult to get 80mm case fans of a good brand(CM,Noctua).So far Ihv come across only 120mm fans from these c/os.
thank you for your reply guys.seems that i really in need of changing that psu.
