swedeee-
The noise at slow speed is a know thing with floating rotors - the mounting bit is alu, the braking is steel, with a bit of space in between to expand under heavy braking to prevent warping hence there's some lateral movement between them.

Well I can't say if the cooling parts really work, haven't even seen any reports on the shimano ice-tech rotors... Superstar components also sells the same model under a different brand http://www.superstarcomponents.com/en/alpine-evo-rotor-arctic-cooling-fins.htm but they don't do less than 160, the only option I know to get a 140mm rotor with cooling parts and 6-bolts is the Discrotor Aircon. Only thing to know is that the cooling parts are not totally fixed, they move a bit, so you can hear sometimes some metal-hitting-metal but at high speeds you don't even notice.
