Wacko, you seem to be an experienced GPU miner so I want to ask you a question. You mentioned that it possible to destroy a card by running it with PL 120. I have free electricity so all my cards are cranked up to the maximum regarding the PL. they work at the cool environment, so the average temp is 65-70 with max overclocking.  Never exceed 80. They work for about half a year now without issues. So the question is - danger of max PL is in high temps only or that process himself (raising the PL) can somehow damage a card?
