Well this is mine, I call it a custom airflow redirection system. Its some paper taped together, and taped to my Freezer 7 / 80mm case fan for more airflow



Not bad for 10 mins work! Lowered temps around 1c idle and 3c load, so quite pleased! When I was making it, the paper was held in place just by the suction alone, which made it much easier and worked well as a proof of concept

Not sure if its the best way to introduce myself to the forum but hey, at 17 I can't throw around the little money I have so you just have to have sympathy!
