Analog Four mk2 - hot and freezes

Based posts on this forum, it is not alarmingly hot. Comparing to my laptop, about 65 degrees roughly.

Also, has been freezing when loading presets, I think only when

Is this a cause for concern?

I bought one in good condition visually.

This is not normal behaviour. Create a support ticket on Elektron’s website, give Elektron as much information as you can about the problem, and ask their advice.
