I have x2 evga gtx 780 sc acx's in sli and I cant overclock them because my temperatures are to high . I have two options ether expand my swiftech h220x by adding x2 water blocks and a radiator which will cost me around $450 . or I can get x2 nzxt kraken g10's and x2 corsair h55's for $170 . my question is . will I see a substantial temperature drop going from my evga gtx 780 sc acx stock coolers to the nzxt g10's and corsair h55's ?
