Phanteks P400S Help

Hello,

Just purchased a Phanteks P400S case and had some questions as the
documentation I got with mine was, well, next to nothing so have some things
I need to understand.

1. There is a fairly large connector tied up in the wiring bundle on the
back side of the case that I have no idea what it's for. It appears to have
a sort of edge connector like RAM does and is around 5 cm wide.

2. I want the two supplied case fans to be controlled via the motherboard
header for auto control and so have traced the two fan cables and unplugged
them from their (presumably) power source/control connectors but I cannot
figure out how these fans would've been otherwise powered and wonder if I'm
missing something - see last question below.

3. So far, I don't appear to be getting the multi-colour front panel accent
LED working. I know one of the case buttons allows control of this but am
wondering how this is powered as I only have power button, HDD LED and reset
front panel connectors available.

Many thanks.

    most cases with fan controllers use the old 4 pin molex plug.

    if not they may use old floppy power or newer sata power plug.

    if there led fans they may need fan controler to output the voltage needed for the led. newer fans will have small 3/4 pins for mb control.

    3. So far, I don't appear to be getting the multi-colour front panel accent
    LED working. I know one of the case buttons allows control of this but am

    most time it controlled by the onboard fan controller.
    Many thanks.

  2. 1. Its for case lightning/fan speed controller. Same connector used to feed your SSD/HDD. You need connect it with your power supply for rgb/fan controller to work.
    2. Use fan headers on your motherboard to kontroll your fans, this way fans will be controlled automatically. Or you can use that fan controller build in your case.
    3. same as 1, that connector u are talking about powers it up.

    I have the same case, and instruction is very clear, step by step installation and connection.

    Actually I still have a particular issue with my LED setup in this exact case. I connected the SATA cable from my PSU to the specified input located in the back of the case as per instruction. However, none of the lights turn on when I press the power button.

    Even stranger, all lights start functioning properly when I manually pull out and reinsert the SATA connection after starting my pc. I tried switching out the order of my SATA plugs (multiple plugs per cable) with SSD first and than led or vice versa. I also tried connecting a separate SATA cable from my PSU to the led, neither seemed to solve the issue.
    Am i missing something obvious here?
