is one gpu block ok for 2 graphics cards

[James Manns]

i just bough aload of w/c parts exc. pump,fluid and tubing
it has with it,
a cpu block and bracket,
gpu bloc
north or southbridgeconfused block
and a 120 rad, i was told this wouldnt be enough for all that so im thinking of getting a lancool case to put it all in as my dell xps 625 will struggle to fit it.

ive looked at some 240 rads on ocuk i dont know which one to get,
also can you have 2 rads in one loop, e.g have the liquid pass threw the smaller then bigger one or vise versa so that i can use up that extra rad.

thanks for any help givin

You can use 2 rads though it will be more restrictive on flow compared to 1 radiator with the same surface area as the two. I've used the XSPC RS120.2 rad, although its just about the cheapest and possibly lowest performing, compared to air cooling I was very pleased with the results using a Q6600 overclocked and a 4870 card in the loop.

hi,
ok then but would a good 240 handle those three blocks and maybe another gpu block??
