False. Unless you cut out the rear exhaust grille AF fans still lose alot of CFM just going through a exhaust grille (unless it's a wire grille)

By obstruction I meant something large like a hard drive cage - not the rear fan mesh. I'm sure an AF120 would better suited there than an SP120, after all.

OP - the fans perked up like that looks nice! thumb.gif I'd still use an SP120 there as Dave also suggested, since the air must still go through the HD cages.

Look at results in the below tests and tell me the grills are not a restiction. biggrin.gif

Martin does a good job of explaining pressure vs airflow
