cooling loop?

[snakegb]

hi

my cooling loop consists of
Ek supreme hf full nickel
XSPC Laing DDC Pump Top Reservoir
Alphacool NexXxos Xtreme II Rev2 Double Radiator

an works nice with my i5 temps are 35-40 idle

looking at buying 2 x 670 graphic cards for sli
now i can get pov ones with or without waterbock already on for the same price but thinking would this mean i would have to add another rad or could i get away with just putting them in the current loop

Personally id be looking at a minimum of a triple rad for that lot.

that aw my fear,

no more room left in my pc and i dont want to go on the outside so fans it is

thanks
