How did you calculate approxx block finding period?

hi!

I have a brand new Antminer S7 batch 11 and and Antminer S5.

I really dont like that S7 working too hot and really really loud, in addition 1200 W is too much power consuption from one location becuase of several reasons for me.

Idea 1:
The fact is that i would like to split S7 performance into 2 custom devices. Of course i can remove hashing boards from S7. By this way i can reduce power consuption to 800W ( 2 boards) or 400 W(1 board). This is okay.

My idea is to plug removed hasing board into S5 controller. Becuase as i see S7 uses S5(+) controller.
The result would be an S7 with 2 hasing board, with less heat, less cables, less consuption, and of course less speed, BUT it would def has a longer lifetime or/and better OC.
And a modded S5 with nice temps, 1,6 Th  on about 380W. + I can use them in different locations


Idea2:
It is really crappy that hashing boards in S7 has small heatsinks and dont use the housing which is a full aluminium, very good for a heatsink. Plus boards are very close to each other wich make less effective heating at all.

Would be great to utilize housing as a heatinks or to completly remove all hasingboards and put there huge heatsinks on each blade and forget original housing.

Would be intrested your oppinion about on this.

Hi Miners!

I would like to buy an S7. May i ask someone to send a coupon?
