Is there any way to make these, T2T, less noisy? I've turned mine right down to efficency setting and still it is running very loud. Update the firmware as well but I think the wife might murder me if I can't make it quieter.
Noise and heat, it's what makes an ASIC miner an ASIC miner

There's quite a few guides and posts on how to quiet an ASIC down, but be careful, a lot of them will make it run very hot.
