Shouldn't be worried about that until 150C+ for the low melting point alloys. There's a reason gpu's are baked at 350ish and not 200, a nice slow melt to the soldier without killing everything else as well.

I wouldn't go past 90C just to be safe though, it should start melting around 160-170f (less than 80C)

Vrms are rated at around 125c operational temp so im sure youre fine at 80-90c

pretty sure the gpu was made in MUCH higher temperatures to where the average heat gun won't be burning anything if your objective is to simply take off thermal glue. BTW blowdryer works.

Guys you don't understand. The process is like reflowing vram chips cause i tell you it is super sticky and if i apply pressure the solder between the vram and pcb will make micro cracks. I've resurrected so many dead video cards with this way. after 100 C all pcb gets affected and a risk of solder cracks ok ? Now it's a 400 $ card and i'm trying to find a safer solution damn.

Have you tried paper knife? Try cutting the glue with it till they are apart.

Try putting very small drops of some kind of solvent at the base of the ramsink. Acetone is probably best.
