i have thought about doing what you said, getting the UN bracket to mount it to my fan, but the thing is i have 2 loops.....where would the second pump go??

If i do put the pump in the loop after the rad then im gunna mount the two pumps side by side on my current UN brackets and have male to male nipples feeding from the radiator into the pump, i think there is just enough room....not entirely sure tho,

but that is only if i decide to put the pumps after the rads....

i can see where your coming from, but i think with that UN bracket u suggested that holds onto a 120mm, it wouldnt give me enough room at the bottom for the rads and pump

ill get the measurements for you 2morrow when my case is empty! i should think u can fit that in the bottom....

good luck!
