Sometimes, when space requirements are stretched rather thin during a system installation, every last inch inside a case may count. When that's the case, one thing you don't want to let suffer in the space jam is your cooling setup. Tightly packed cases and components will have less room for airflow and ventilation, which makes having a strong cooling setup even more important than a larger chassis. When this is the case, you may want to look into thin profile fans which may give you a little extra clearance inside your case and still allow you to maintain some active airflow.
