Adding to the 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

my i5 temps are 35-40 idle

am looking at adding some cooling for 2x 670s but have a couple of questions for you Gurus out there

first thing do i really need to add a back plate as these are the FTW's and come with one also ive read these need the 680 waterblock is that right?

ok thinking of this:-

adding 1 x twin 120 rad and an extra 5.25 drive bay Reservoir

loop looking like this

pump/res > cpu > 120 rad > gpu > 120 rad > 2nd gpu > 5.25 res >

can pump handle this?

also currently tubing is 11mm should i look at getting wider

thanks
looking forward to your thoughts
