I watched videos from northwestrepair yt channel and he always said that you have to replace the thermal pads with exactly the same width ones to avoid strain on the gpu. That makes me dont want to replace thermal pads

Thats a good advice, for that to work you just need to remove the solder, reball the memory ic and solder back if there are no broken/ripped pads. If there are any ripped pad then still can be done but you need an expert at microsoldering to rebuild the tracks

It wasn’t a silly question after reading the OP answer xD
