Issues with IDEX 4028 part cooling fans quickly changing speeds
So how do you suggest that they should be wired up? If this is the case regarding the amperage then why are others not experiencing the same issues? Sure with IDEX and both 4028 fans spinning up all IDEX users will be running into a similar situation?
Could you please explain what you mean by a step down converter? Is that what they also call a BUCK converter?

Issues with IDEX 4028 part cooling fans quickly changing speeds
I'm going to try and wire the fans up to a 12v PSU tomorrow.... But I shouldn't be needing to as the MAX should be able to cope with the 12v fans. The PWM has always been on the toolboard. It was only take off for testing purposes. I tried wiring the fans back to the 4 pin fan ports on the MAX back that made no difference.... Still experiencing the same issue when suddenly increasing or decreasing the speed of one of the fans while the other is running.....

Hi, if I'm connecting both the positive and negative to the PSU it obviously won't use any enable pin so should run at full power until Klipper boots??

Yes this is powered through the octopus Max board, just the pwm wire on the toolboard. I've tried rewiring the fans up as 4 pin fans going back directly to the MAX board but i have the same issue. seems like they aren't receiving enough juice or is being throttled back. I will try re wiring a 12v psu tomorrow and report back

Ok, so when I disconnected the PWM pin from the toolboards and started the printer the FAN didn't start spinning at 100%, they didn't spin at all. I then increased the fan speed on t0 to 1% and the fan started spinning at full power. I then changed the fan speed of t0 to 0% and the fan stopped. I then repeated this on t1 and the same happened. I then set t0 to 1% (full power) and did the same with t1 and both fans instantly turned off!!!!

Ok. That makes sense. But why would they lose a signal and not be able to establish it again? I have the EBB42 1.2 version

Adjusting the speeds after they lose power makes no difference. They just won't start spinning again
