hi, i need help coming up with a delayed shut off circuit.
here's what i need it for:
a: i shut off my video game console
b: the cooling fan(s) stay(s) running for lets say 5 minuets
c: then once time has reached around 5 minuets fan(s) shut off.
the reason for wanting this behavior is that the current design for the xbox 360's gpu heat sink is inadequate. so currently i have an externally powered fan blowing through the heat sink. but i forget to shut it off sometimes. not a huge deal but it does add to the power bill and i'd like to eliminate the externally powered fan.
Details:
fan(s)
power: 12v
supply(from console):likely 12v or 5v
also since this will be inside the console(hopefully) it needs to be somewhat small but not too small.
i have no restrictions on how this is done. could be a 555 timer or something else.
thanks in advanced.
