airflow disabled by huge cpu cooler

[Jip_]

so i bought a new Huge cooler. it does fit in my pc, but it is in front of the fan that pulls hot air out of the pc. when the sidedoor is closed the fx-8320 gets to 65C when gaming. when i push off the sidedoor it is a normal 50. How can i fix the airflow without removing the cooler? my case is the coolermaster k280.

thanks for your help
