i would like to add extra 40mm fans in front of the harddisks
in a dell optiplex 760 desktop case.
i need to find power for these fans and there's nothing spare in this dell case.
possible free connectors / ideas are:
- free internal USB (INT_USB)
- PS/2 or serial connector (SERIAL2)
- split the fan connector (FAN_CPU)
- get an extra molex by adding a MICRO_PWR-male MICRO_PWR-female molex.
my first idea - probably the most obvious - is to split the existing fan-connector.
the fan connector that is in use for the front fan is a 5 pin connector.

where can i find a description of such a 5-pin connector, 4 pins are in use, DC12V seems ok. how can i connect it to the 2 or 3 pins usually in use by fans.
should i use 1 or 2 x 40 x 40 x 10mm fans to cool 2 harddisks ?
what would be the necc. needed air flow to really make a diff. ?
what would be the adviced fans when i want to keep acoustical noise as low as poss. ?
candidates i found::
any advice by the experienced ?
