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.
