I didn’t learn this technique from here, but I have been keeping my Nvidia GTX 660 Ti alive for the past year using this same trick. It was due to be replaced with a HD 7970, but this has kept the GTX alive and well. Thanks for taking the time to write a iFixit article about it! Also, never ever put the GPU in the oven with it’s chip facing down. It will fall out of it’s socket if you do and once it goes out you’re pretty much out of luck forever.
