due to the heat today i decided its about time i started saving my pennies towards another fan or maybe 2 ?

currently have one wedged btween an ally rad and grs ic, id like to know what would be my best upgrade path, one more in there ?

one on front ?

or leave that there and get 2 on front ?

i dont mind using older fans , i could even get a giant single fan up fromt ?

suggestions ?
