Power supply gets very HOT with MMU2S
My Mk3 PSU used get quite hot before i added the MMU2S. Now it gets very hot - too hot to hold on to for more than around 10 seconds.
The MMU stepper motors are also warm, so I assume that's due to position-holding current, which obviously adds to the PSU load.
The PSU is free-standing with no active cooling added.
My question is, is it expected the PSU should become so uncomfortably hot after adding the MMU2S?
Does anyone know if the addition of the MMU2S leaves much headroom for the PSU to also drive additional items (my Lack enclosure uses some nice bright 24v LEDs - currently disconnected)
Would it be sensible to add some fan-cooling ?
Thanks

It would seem they fixed that in fw 3.7.1 https://forum.prusa3d.com/forum/original-prusa-i3-mmu2s-mmu2-general-discussion-announcements-and-releases/firmware-3-7-1-final-for-original-prusa-i3-mmu2s-mmu2/ They talk about rambo board and psu overheating fix.
