caveman_1990I can see something wrong with the placement of your radiator. You placed it on the bottom of your case which would be unable to cool down. Hot air rise up >_<. pretty good case thou 7/10

MIP_1983There are two radiators. Its the black ice radiator on the back that does most of the cooling, the one at the bottom does a minimal amount of passive cooling (with it just being outside the case, the outside air actually does quite a decent job of cooling it there), there's a small amount of gap above it to allow air to rise. I know the ideal placement would be at the top, but that would ruin the aesthetics of the case. I still get 33C idle and 37C on load, and its very quiet, so there's no real need for me to move the 2nd rad.

caveman_1990That is a pretty good temperature. IMO you would not need the second radiator just like say. You would take away the second raditator because it only cause your water system to flow slower. Take it out and see what the tempature is and if it is not better than put it back to the orginal seet up.

Anyway when you say its 33*C idle whatis the room temperature?
I am getting 18*C idle with 266x9=2400MHz and room temp of 17.5*C using TAT
