I’ve been using this after, like you said, 2 weeks of full-time silent 3V fan, leading to a sudden increase in noise and worse performance (it essentially broke), and… damn, it works even better now, it’s more temperature-stable, and it’s absolutely silent.

The case is really cool once set up, I love how it feels. It’s got a purpose and it’s going for it. Really feels like it was made 1000% for dissipating heat. And it works like magic.
