Curious to whether or not you have a garage.. i went straight from an S2 to an S7 and the S7 litteraly made me jump when it first kicked on lol. I ran it on the house for a few days and it was pretty much unbearable.

I ordered this and stuck it in he garage:

(Though currently unavailable, I vouch for LEA, it does the job)

Here is a variation. (Im not familiar with this company though it serves the same purpose)

Litteraly internet through the walls. Plug one in and plug an ethernet cable from the router to the device. vice versa on the other side accept from the miner to the device and you have a hashflow. * <-- that, i like that, *hashflow* lol

Later i found that due the the warmer climate that i now reside in, temps were becoming an issue in an uncontrolled environment. Then came:

(Also vouch for them. They have a personal domain which i dont remember, but send a thank you note wih url attached upon delivery of pruduct)
Get an attachable tube from a hardware store and dump the hot air out a window if possible.

One last thing is the duct will cause a rise in temps. A buddy of mine, who gets a kick out of the nature of bitcoin surprised me with a good air blower to help with my cooling issues. (i would say this could cool two units if placed right and need be)
Good up to 105°F:

There are other, more affordable blowers, though they might only cool a single unit.

Sorry if this was a bit excessive. I'm really bored... and also trying to help you out
