1) I agree here if you were a dedicated miner who just vents their air outside, but undervolting makes sense who pay electrical and cooling costs (ie. their cards are in a gaming machine). At that point your net revenue may come pretty down close to 0 after cooling costs unless you undervolt.

That is nonsense.  Gross revenue is currently ~4x electrical cost.  Even with 30% overhead for cooling it is >2x.  Undervolting doesn't improve profits.  Undervolting is useful in large farms where you simply can't handle the heat.  I updated post above to show that.
Yeah, not quite sure why some of these ppl seem more concerned with efficiency than profitability.  *scratch*   But, then, I guess you also have people loading up with 7970's that will decrease in value like nobody's business, so..

Couple months ago, I never undervolted.   Now I do so during the day only, because of heat issues (considering different solutions as to where I wouldn't have to do this).  Then, I'm speaking from a perspective of anyone that gets electricity for, oh, I don't know, probably 15-20c or so or less.  I pay ~8-9c per kwh.

Dacentec Dedicated Servers (Lenoir, NC, USA) from $25/mo & Time4VPS Storage VPS' (Vilnius, Lithuania) from €18/qtr & Hetzner's serverbidding, from ~€20/mo -- had bitcoin nodes & p2pool (dacentec, hetzner) for several years on these.  Only two are affiliate links too, kek! -------  Feel free to join my G2A Goldmine Pyramid Scheme Team, or possibly even buy a Steam game from there.  Maybe.
