I have a dead R9 390 Nitro and want to see If I can revive it and start using it again. I am not really concerned about how long it lasts. I do not have a heat gun but I have a soldering iron. Is it possible to touch the places where the solder needs to be melted with the soldering iron or will that damage the card? I also have a toaster that has had heating limits removed so it can reach a fairly high ambient temperature in the toaster. Is this a feasible option as opposed to the oven method?
