SPLITTY9 splitter for up to 9 PWM fans ?

Friday, July 22nd 2016, 7:43pm

Hi,

The Splitty can handle 9 PWM fans in a cluster. I understand that only one fan in a cluster will need the PWM control wire/signal enabled, the others [up to 8] will have their speed controlled as a result i.e. they don't need the fourth [PWM] wire enabled. How is this accomplished on the Splitty board ?

Thanks,

LJ

Well, THIS would be magic because it is not the way how it works ;)

The input is connected 1:1 to all outputs so in the end it does not work different to a y-adapter. The only special thing here is that with the jumper you can disconnect the rpm signal pin from all outputs but the first one. With all rpm signal pins connected you would get no useful signal. While it makes no sense for fans to have all pins connected, it is great for the aquabus because it requires all pins on all ports.

Thanks Shoggy, it all makes sense now.
