My case is a vacuum cleaner!

[DanishGuy]

I have a very small desktop case, which only has room for one intake fan...
As you can see I need a more effective 80 mm intake!

-----------------------------------------------------------------------------------------------------------------

Case (Intake) 80 mm Papst @ 1.500 RPM = 12 dB(A) +19,4 CFM

Case (Exhaust) 60 mm Papst @ 3.900 RPM = 27 dB(A) -17,1 CFM

Slot (Exhaust) ?? mm ????? @ 3.200 RPM = 26 dB(A) -42.0 CFM

PSU (Exhaust) 80 mm Papst @ 2.600 RPM = 26 dB(A) -34,1 CFM

PSU (Exhaust) 92 mm Papst @ 1.950 RPM = 23 dB(A) -35.9 CFM

-----------------------------------------------------------------------------------------------------------------

This will result in a 109,7 CFM vacuum cleaner...

I bet that intake will spin at 1500rpms without power.

I think you're right, it almost would!

[EDIT] Or maybe it'll shoot off the wall if I place it too close.... (My table has wheels)
