So I recently opened my Acer Alg laptop for thermal repasting, like the cpu gpu paste and vram thermal pads But as soon as I unscrewed the thermals , they didn't like came off ,they feel like they are sticked as like through adhesive , the left side fan is coming off easily but as it is attacked to the vents and the right side fan is also not coming off with vents , so now how should I get the thermals and fans off the rig to repaste all that ?
