Firstly, you should clean and replace the thermal paste with Arctic Silver.
I did the oven reflow and performed this vent mod so it sucks in the coolest possible outside air directly to the processors, and always leave her upright.
Been working like a true champ now for a month.
If you didn't go out and BUY new thermal paste, and cleaned that schite off the processors with alcohol and use the perfect amount, you are not going to have a working system for long lol.
I got my motherboard up to precisely 400F/200C in my oven on the top shelf for 10 minutes flat. That was enough to reflow the solder. I wrapped it up in aluminum foil(shiny side facing out), and cut 2 perfectly square holes for the processors to get all of the heat from the oven.
I followed this guide here and I swear by it.
Edit: Just wait here a Goddamned cotton pickin' minute! Did you just say you used a curling iron to reflow!? How on earth did you manage that!? You laid a curling iron onto of the processors didn't you? Jesus H Christ son, what did you expect? You are reflowing by thermal conduction!
Oh teh lolz!
