MK3S Heatbed Noise
Hey Prusa SMEs,
I am new to 3d printing all up and purchased an MK3S kit to learn how they work. One thing I'm curious about though is when I turned on the machine, I hear what sounds like a faint fan noise coming from the Magnetic HeatBed base. It kinda a whssssh type noise, nothing super serious, but just thought it was weird considering there's no moving parts on it.
Thank you!

I would take a video and contact chat support. They will ask for it.

TLDR; a faint amount of noise is normal.
It turns out there's two noises; 1 coming from the plate, the other actually coming from the PSU. The latest PSU does make a small noise (it must have a fan inside, but haven't disassembled it). When the bed is heating, support mentioned it may not be uncommon to hear a small hum since it is drawing power to heat the board.
Hope this helps someone else! 🙂
