Thank you for your comment. My damper is 5.8mm thick, so a slight offset is possible (a user below commented on having 8.66mm thick dampers, so this is absolutely worth checking). I have no issues with the temperature, but I haven't printed anything longer than about 5 / 6 hours. My steppers are not really hot at that point. But this may be different for you. See also the comment/reply below of user urban07 who has made a cooling solution.
