Fractal Ridge CPU fan tunnel

i just built my first mini itx build and noticed my cpu getting hotter than id like as my cooler has a height of 45mm but the case has clearance for 70mm. so i made this simple clip on fan tunnel so the cpu only pulls in fresh air. you can easily make the tube shorter or longer depending on your cooler, no screws just clip it on and go. this brought me from 95c under full load to 80-85c under full load.
