Idex fans wont shut up . Part Fan and Toolhead Fan on full
What is up with the fans? Just got my Idex v-cove 4 500 up and running and the fans are so loud and stay at 100%. Why are the tool head fans even going by defaults when the heaters aren’t even on?
I am using the default fans that came with the system. The only thing I did differently from the walkthrough guide is follow the instructions on os.ratrig.com/docs/guides/4028. because someone commented that this was assumed setup with rat os v2.1. so i have T0 pwm plugged into what bigtreetech shows as J50 - and which appears to be mapped to PA8 which has given me control of T0 part fan. but i didn’t know what to do with T1 pwm part fan. so i plugged into J51 - but dont know how to enable/use that pin in the config file. should i just take both pwms and punch them down to their respective tool boards?
even if i do that and it works, how can i shut those damn toolhead fans off. they are so freakin loud i can’t even think about doing the configuration cause i have no control over them. going crazy! #fans #toolhead

Connect them down to the toolboards. Set it up correctly and they'll quiet down. It may be loud while you troubleshoot. The guide should help you find the right pin names; it doesn't sound like you are doing a strange setup. Without the pwm pins connected and getting a proper signal they will run at 100%

With the pwm disconnected the fans fail "safe" meaning they'll do their best to keep whatever cool.
Should be able to disconnect power while you play with it, but only hook it back up when the whole thing is powered down. I'd be worried about a current surge
what does play with it mean? The fans are too loud to even work in the same room. I don’t understand why the toolhead fans are 100% or how to get control over them so they only turn on as much as needed or wanted. I also need to know how to enable a specific pin off the octopus. I don’t need a temp solution where i just unplug them because without fan control i can’t even see using this thing with as much noise as it spits out.

I sadly am not near my computer to point you to the right pins
just punch the pwm to the tool boards as instructed in the walkthrough. disregard absolute’s suggestion in the guide comments that it should be anything else.
