Hello there!
Just got my S9 sound monster, so a few question appeared:

1. Chip 1 temperatures are absend - there are hyphens there, wtf?
Chip 2 temperatures difers a lot - 72 58 and 62 degrees acordingly. Is that ok? It's 4200-4600RPM.

2. In Miner General Configuration there is no checkbox for 80 degrees shutdown and field for RPM setting is absend as well. How so?

3. What fan to choose instead of the default one to cut the noise? Delta AFC1212DE 1,6A is reccommended by many, but lots of controversial info around there.

4. Seller said ASIC should not be turned on and off often for it would reduce its lifetime, is that true?

Many thanks!
