70-75°C - 24/7??
and +15% plimit
I shed a tear when I read that ;( you're raping your cards...wearing them out hard...
I learned my lesson the hard way when one of my hawaiis died in the summer of 2016 while mining for 4 straight days around 70-75°C
thankfully only 1 card died... :/
Since then I'm taking card temps very seriously and precautions making sure my cards work in an adequate environment maybe even more than really needed just in case.
Don't ever run cards above at least 70°C core if you want them to live long and without any potential issues.
I usually run my fijis and hawaiis always around 63°C max.
right now in winter they are below 60°C at all times and that's with fans running at around 60-65% power
so yeah im obviously downclocking, -10% powlimit atm
you have no reason to be dissatisfied with the performance of your vegas especially in regard that you're running them 12 in a single rig
One of the rigs I have is a 6 card rig consisting of 4 fijis(nitro furys all) and 2 hawaiis, best performing and worst performing fijis differentiate about 4-5% in hashrates...it's pure silicon lottery man... there's nothing wrong with your cards hashing, if you apply 4-5% difference between your cards you get the same results you're complaining about.
on the other note, I noticed it's normal to have a little bit worse hashrate across all cards when running larger number of gpus in a pc than usual, although I can't confirm for sure by how much or at all... just my opinion.
so to answer your questions and few free tips:
1. Run your cards below 70°C since your clearly intend to have them working for 2+ years I suggest @ 63°C max. your cards will thank you in profits later as much as they live the longer the better
2. I don't own any vegas unfortunately but the general rule every serious miner applies is downclock/downvolt/tweak until you have stable temps, don't be driven by hashrates,
card temps are FIRST PRIORITY! then according to temps try to get as much hashes from your cards as possible!
Mining is a long-term game, remember that!
3. Probably, wouldn't know for sure, as far as I know less tweaks in wattman means more stable miner, set gpu settings in bat/config files.
Happy mining!

Thanx a ton for the advice bro, I was able to maintain my temps between 60-65 by cooling the ambience in ac. So basically are temps upto 65 degrees safe for the long run or yet you recommend to lower the temps by sacrificing the hashes (undervolting+underclocking) because i was able to achieve stable hashes of 2030+ with 65 degrees max under ac keeping the same old settings of +15% power.
However i am willing to bear the electricity charges for those tempting hashrates
