Well, this is a fine pickle.I have an old ATI all in wonder 8500 videocard whose gpu cooling fan has recently rolled over and died, so I thought I'll just replace the fan and be off in happy land. Unlike modern cards, this card has a heatsink and fan glued onto the gpu.
So, as I've done in the past, I wrapped the whole card in an antistatic bag, then put it in a freezer bag, and placed it in the freezer for an hour. This is to make the gleu brittle. Then, I put a credit card down on the pcb board to protect it, took a screwdriver and placed it beneath the fan and gave it a little twist....pop, off it comes, just like it always had when I've done this before.
OK, before I put the new fan on, I need to clean the old glue to from the GPU.
Don't want to risk anything with the GPU, so I am experiementing with the heatsink and the thermal glue that remains there
Tried heating it up with a blowdryer and scraping it off. Nothing
Took a little Dad's Drip Strip, which is similar to Goof off, which takes just about anything off and has worked on other cards I have done this with. Hmmm, nothing..
Tried acetone. Nothing
Tried paint thinner. Nothing
Tried lacquer thinner. Nothing
Tried lighter fluid. Nothing
Tried a citric cleaner (this is normally a no-no, since it leaves oil behind, which will decrease the heat transfer later but I was getting desperate). Nothing
What the heck is this crap? Anyone ever had to remove this stuff from an ati card from around 2002? What did you succeed with
