Antminer s9 or t9

[MigueJuve]

I want to buy two machines, what should I buy? S9 or T9?

I need to know wich one is more noiser and gets the highest temperature le el.

Power costs are no problem in my country.

I believe the S9 and T9 are basically the same when it comes to noise and heat output.  The main difference between the two is the T9 trades efficiency for reliability - that is the T9 has less hash for the power but they are way less likely to have a failure of some sort.  Check the S9 and T9 threads for more and more and more on the subject!
