Tell me again why do you want 5 ohm?
I gave my answer above.
1) It reduces inrush current max.
2) It reduces di/dt on inductive components (which are unknown).
3) It reduces dv/dt on capacitive components (which are unknown).
4) We don't know the minimum resistance since we don't know much about the circuit, but given that there is no "maximum resistance" calculation for thermistors, it's better to increase resistance than decrease it when faced with a failing thermistor.
I would turn this around and ask what benefit you think there is by reducing the resistance? I listed the possible benefits that I'm aware of from such a reduction, and why I think those benefits aren't as great as the benefits from increased resistance.
