my MD30RZ always has a bit of "turbine" noise....
suggest larger inlet hose, 1" ID or bigger even (#1 issue IMHO)
is the T line off the T at the pump outlet?
suggest you pump water from bottom of RAD's to the top, not top to bottom (clears air much better, you may have air pockets still)
do you see any bubbles (small & fast moving)?
