The Lyr+ is should not be that warm. It's barely above body temperature when I touch it.I have my heating set to 73 and that's just a step below warm for me lol. The combination gets real toasty for me, especially in the middle with the heat of the Bifrost rising and the Lyr just being a warm amp in general. The fan works great with the chassis of both now feeling cool to the touch
My first Lyr+ was hot af just before dying out of the blue. Be careful if the Lyr+ start to get very hot. I'm not the first user to have a toasty Lyr+ that die.
