As a prior owner of a XS7, Extreme 76, Triton 61, M3M , Rd700GX1, I have a fair perspective for comparison.
As far as folks that have been highly critical and vocal of build quality, I don't share your critique. If you own a Kronos, its possible you received a 1st run that wasn't as solid as mine. Or maybe you demo'd a board at Guitar Center which was a return and smacked around by 5 year old's.
Or maybe you are from mofotator
The fan is NOT noisy. I hear it and its slightly above audible. my room is very live with wood floors, and minimal furniture. Fan noise not a distraction.
The RH3 is a nice surprise and I am a piano player. RH3 feels and responds great and I am used to the RD700GX1.
My RH3 is flawless, no spaces or gaps.
Navigating the small fonts/sub menus ( characters are somewhat crowded on some screens) will take some practice . I use the up/down arrow buttons in sub menus as an alternative.
I also have adjusted my stand lower so I have a better view of the Touchscreen.
The LCD resolution is bright and detailed. I don't know how it fares in direct sunlight.
I am ordering a pad controller to better use the Karma pads. a
pad controller is inexpensive & will sit nicely on my 88.
All the Kronos buttons and dials are solid. I think they are a step up in quality compared to the Extreme.
The sliders have a little play if you wiggle them sideways. But who does that ? The Kronos up/down sliders are perfectly ok. The XS motif sliders are a touch more solid in comparison.
The Kronos looks AWESOME. The chassis is extremely impressive, all components fit neatly and perfectly.
BTW, my serial # is 540
