Got my EVO. The serial code was on the fan only. Registered it on CoolerMaster's website. Thanks guys.
Btw, coolermaster has changed the way the fan's hooked to the heatsink. Previously it was using metal hinges. Now it's using a plastic frame that's attached to the fan. The metal clips was a lot better. The plastic frame looks flimsy to detach in case you want to flip between push-pull config.
