They dont. still ok airflow but they lose a lot in the pressure department. So if you have stuff that blocks some airflow the slim ones will perform worse than the normal 25mm ones.
I only used them when I absolutely had to for clearence reasons and that was only for a case fan, Id never trust them to cool a CPU since you want that static pressure to push air through the heatsink fins.
