Hey all, as BTC price has been increasing, daily earning with Vii have been slightly increasing also.
Do you think it's still worth to push these cards to the highest limit possible; DaggerHashimoto @ 91 MH/s . Earnings go to around £1.90-£2 each GPU.
But the temp also increases to around 95-100 degrees.
I know it would be very bad in the long term and the lifespan won't be much long.

Not just this card. But no, why should you aim for best hashrate, not the most efficient? You'll get more returns after your electicity bill if you aim for efficency.

I believe that is a common misconception. If you've secured a low enough electricity pricing with your current power company, you can still make better profits (after the power bill) while happily burning away electricity. The whole point is about finding a balance of revenue vs. efficiency vs. electricity rates. With my rates I have no problem running my 7's all at or above 90MH/s in an open air rig.

At 90 mhz how hot are your cards, I'm running mine at 75 mhz because they get so hot.

78 C with box fans blowing on them in an open air rig (exactly the kind BBT uses). Just undervolt them and make sure they have adequate (external) cooling.

P.s. I think you misspelled Mh/s.
P.s. 2. It's normal for these cards to run hot. They'll throttle down once you reach high enough temps. I'm not sure but I think 83+ C will start throttling.
P.s. 3. If the card is inside a computer case, it's possible you may never be able to run it at it's full potential. You'll need extra cooling.

Good luck!
