SP20s tolerate heat a bit better than S5s, in my experience with a limited data set, but mostly 'cause they are a TON more configurable.
They're quieter, but not a LOT quieter if you are pushing them anywhere near their full hashrate.
They ARE a lot quieter if you undervolt them some, can still get 1.3-1.4 GH with a fairly low noise level and close to S5 efficiency in a cool room.

My "summer" rate here (mid-June to mid-Sep) exceeds 15 cents/KWH during the day easily, due to ToD rate adjustment, the OVERALL is about 14.2 but that's only WITH ToD overall adjustment, without ToD it WOULD be a hair over 15 I believe - this is in Iowa with Alliant's ripoff "tons of extra fees" rate BS. Our rates where I live have gone UP at least 3 cents/KWH in the last 5 years due to Alliant adding way too many surcharges with almost NO reduction in the base rate to compensate.
The rest of the year isn't so bad for those that use a lotta electric - first 1200ish KWH are sorta pricy, but after that it's around 6.7 cents/KWH for the "anything over" third residential tier.

3.9c for 1kwh, 4.9c for 2kwh, 6c for more than 2kwh, 6mo from GEXA

and after the 6 month "teaser" what does it go to?

I still have 2 S7 coupons available at 0.1 Bitcoin each. I don't live on this board, so don't expect "instant" response to mails, but I WILL get back to you.

it's not a teaser, just 6 mo contract...after 6 mo you get a different contract..this is how it works here, although i usually get a 12 mo contract.
