- Easy to over/underclock.
Cons:
- Fan is incredibly loud and the speed is unchangeable.

- Very temperature sensitive.
- Help page seems lacking.
- Packaging. Not impressed with the cardboard padding.
Overall: 8/10 (9/10 with fan replacement)
Although it's not perfect, I will say it's better than any other miner I've owned. My main issue with the sp20 is the noise. I know many have complained about it but I was genuinely surprised by how loud it is. I'm sure it would be much more tolerable if I was able to lower the fan speed, but at it's current setting (80%?) it's far too loud to be a home miner.
Overall I'm very impressed. I can officially confirm that all the hype about SP-tech gear is warranted. I will definitely consider buying their next gen hardware but only if they address the noise issue.
