After watching the most recent Tek Syndicate video, "How To Fix A Dead Graphics Card", I wondered if heating up and reflowing the solder would actually work? I understand that the video is a joke but heating the graphics card up in the oven does kinda make sense? Anyway, I'm purely curious to whether it would actually work or not? I apologise in advanced if this makes me sound like a fucktard.
I would assume that the plastic in the fan would start to melt before the solder.
Yes it does work, that's how surface mount soldering is done, the parts are put on using an adhesive solder paste on the pads to be soldered and cooked in an oven to melt the solder and bind the components to the PCB.
In order to reflow you need to set your oven to about ~160°C/180°C (recommend buying a cheap toaster oven so you don't contaminate your food oven) and place the board in WITHOUT the shroud, heatsink assembly, or anything that is not the PCB. Cook for 15 minutes and presto, your reflow should be complete
I see... I thought it seemed plausible but then at the same time it seemed like one of those dumb internet hoax things ahaha! Thanks for explaining it!

This works! I've resurrected laptop motherboards this way. I also use a heat gun for more precise control when avoiding plastic parts on the board.
Yep. It works. Though, from experience, usually only temporarily.
