4028 starts blowing after ~1h of inactivity/standby
i am running a sanyo on an SKrat with the dedicated 4 wire connection and the standard configs. i think the follwing happens but i want to be sure: i think after an hour of inactivity the printer goes into standby and the fan will blow at 100% because of safety reasons. I wanted to double check since the OS page states similiar "mal"function can fry the your board.
thanks in advance for any insights

anyone?
Not much of this makes sense to me.
The 4028's won't spin on the SKRat 4 pin headers unless told to.
Idle mode just shuts off motors and heaters.
What exactly happens after "an hour of inactivity"? What standby? The fan blows on shutdown (errors).
since the OS page states similiar "mal"function can fry the your board.I'm not sure what you're referring to here
after powering it up and doing nothing for a while (around an half an hour to an hour i think) the 4028 just goes to 100%. i might be an error, because it seems i need to rebooth to interacrt with the printer again.
im referring to the middle of the https://os.ratrig.com/docs/guides/4028 page.
Connecting a 4028 fan | RatOS
4028 server fans are becoming a popular option for part cooling because of their light weight and great pressure and flow rates. In this guide we'll go over how to connect one and use it for part cooling. 4-pin fans usually aren't used in 3d printers, and many boards only provide 2-pin ports, but fear not! There's always a way.

im referring to the middle of the https://os.ratrig.com/docs/guides/4028 page.That is not applicable to dedicated 4-pin headers, and it's also a very different issue (it's 100% during power up until klipper boots)
