Theres a big buy happening on Xtremesystems and I was thinking of getting one of these pumps, from the "How much pump is enough? How much is too much?" thread im left unsure about what to do.
My loop contains LRWW G5, AquaXtreme MP-1 and a PA160. Now I read the Rd-20/30's are really quiet so I liked the idea of them, the price I can swallow (ish..

) but with the PA160 rad do you think the heatdump might be too large to negate the gains that the pump provides.
Oh and theres no space in my case for another rad so this is all I got..
Thanks!
