The idle temp is really not the issue, it's the load temps that get out of control. There's a 10C+ difference between 4GHz and 4.2GHz. The pump needs to be quicker for 4GHz+ overclocking.
What are your ambient and what were your previous temps?
Also are you sure it's making good contact?
Oh and the "pump" is not what usually cools the system, as long as you have good enough flow then that will not be bottleneck. The H50's pump is not strong but it's good enough for what it is in the loop. The radiator however has very little surface area, I believe it's on par with the stock Intel(non-980x) heatsink. The temps though because it is watercooling makes the most of that surface area.
My personal expereince is it's just to thin, you could try to modd it and add in a thicker rad or a 240 rad, but if I were you I'd just go with a nice thick Black Ice 120 rad, that way you don't kill the pump.
