Anyway you cannot live in fear of using the stuff thats rightfully yours, just enjoy it to the max, if it burns and they dont change if F**K them just buy another brand I know its a lot of money but it's not like losing a leg or an eye, that's my attitude to this kind of stuff. If you have the money to buy the topest of 4090 cards, REV IT TO THE MAX, and stop being afraid otherwise you might as well don't buy anything, the worst case another 2000 bucks but you had a blast burnin it
