Fan connector JST type and pinout for rear case fans, Pironman 5-MAX

[GOTO_GOSUB]

I am going to replace the fans supplied with the Pironman 5-MAX for Noctua. While I am waiting on delivery of my cases could someone please advise what JST type connector are used for the rear case fans and the pin-out.

I know that the fan on the cooler will be a JST-SH plug as this connects directly to the fan header on the Pi 5. I’ve got those and I know the pin out having made my own fan wiring harnesses before. It’s the 2 fans at the rear of the case that I am interested in.

Looking at the assembly instructions the Expander board appears to have 4 pin connectors of which it is implied that one pin is probably used to enable the LED’s on the fans themselves. Presumably the fourth wire is the PWM control. I would like to know what type of JST connector has been used for the fans on the expander board and the pin out order so that I can make my fan tails in advance. The Noctua fans do not have LED lighting so I only need to know what the pin outs for J4 and J5 are with regards to +5V, GND and PWM.

It is worth noting that the Expander board RGB fan pins section is not clear on this. Early on in that section it mentions non PWM fans but then mentions that these are turned on or off according to the system temperature. It may be that the fans are not, in fact, speed controled and are either on or off, and that the other 2 pins (ie not the +5v and GND) are in fact simply power to the LED’s.

Thank you.

• Our RGB fan terminal is independently switched via the 1.50 terminal 4P, which is a standard JST-type connector.
• Yes; the pins control the fan and LED switches, but they cannot control the fan speed.

Thank you for this, that is very helpful. A JST connector on a 1.5mm pitch specifically makes that a JST-ZH connector.

Sorry, as a new member, I can’t upload more than one photo to a post at a time, so I’ll have to make multiple replies to my comment to upload the other images. (Strike that, I now have full access)

Hi team, I was wondering if I can get some clarification. Maybe I’m missing something. I am working on modding my pironman 5 max fans with Noctua fans similar to GOTO_GOSUB, but I came across something strange.

The wires on the original Icecube RGB fans, yellow (positive +) and blue (negative -) wires control the fan. The red (positive +) and black (negative -) wires control the RGB. Demonstrated with this image - RGB not connected.

Based on the image from SunFounder_Moderator, it shows that the LED Negative (pin 1 image below) should be connected to the black wire and pin 2 should be connected to the red wire.

However, I am noticing in the “Unboxing & Assembling the Pironman 5 MAX Case for Raspberry Pi 5” YouTube video, that the blue and yellow wires (aka the fan) are connected to the RGB pins. And the RGB pins are connected to the fan pins.

While modding my Pironman 5 case to work with the Noctua fans, I pulled all of the wires out of the original JST male connector so I could reuse it. I am debugging the Noctua wires to figure out which is positive, negative and how the PWM wire works - and needed to reference the original wire colors for the Icecube fan. Since I already pulled all of the Icecube wires out of the male JST, I had to go to the YouTube video to find the original ordering. I put them back in the male JST in the order shown on the Pironman 5 Max assembly video: https://www.youtube.com/watch?v=Iucf51zInWQ, but I noticed the FAN | 6 and FLED | 5 jumpers are swapped.

Does anyone have an image of their pironman 5 max IO Expander with the original fans still connected so I can reference what order their colors are in? I’m curious if this is a bug with the SunFounder Pironman 5 Max hardware itself or if I am missing something.

From what I can tell, the colors should be this:

pin 1: black (rgb -)
pin 2: red (rgb +)
pin 3: blue (fan -)
pin 4: yellow (fan +)

But the video I used to reference the orignal colors have them as

pin 1: blue (fan -)
pin 2: yellow (fan +)
pin 3: black (rgb -)
pin 4: red (rgb +)

Sorry for the confusion. The fan sample shown in our video is different from the final retail product, so please do not refer to the color order in the video.

The correct color configuration should be:

Pin 1: Black (RGB -)

Pin 2: Red (RGB +)

Pin 3: Blue (Fan -)

Pin 4: Yellow (Fan +)

The pinout diagram we provided is correct.
