Well it is a good question.  It would be an issue  if you can not cool the gear.  even  the max temp allowed to run the gear 30c or 86f

resulted  in  1545 watts used vs 1366  at 67f

So  87f = 1545 watts
and 67f = 1366 watts

This means I can not put 20 in my solar array  which will go well into the 90's in the summer.

But even if you run  at 85f  you are eating  150 to 180 extra watts.

If I get 10 or 20 of these I need my buyers to know the heat limits.

To be fair the spec page shows 30c as the max  it also shows a +- 20 %  range which we know know is dependent on heat in your mining room.

Part of my job it to try to show what you would be getting into if I sold gear to you or if you buy from a builder.

@ taserz   the only gear  I can run safely in the array in the summer :

 the old  s-9 set to lower freq
the L3+   set to lower freq
the dragonmint T1  set to efficiency and with -ck's throttling  feature when gear gets hot.

the last youtube I did  stunned  me  I dropped the room temp from  87f to 76f by opening my garage doors  and watts dropped from 1545 to 1425 in well under 8 minutes as the room cooled.


Today it is 48 f.  I am going to test this again. Using a 2450 watt hp psu.
