Review (4/5): Good blade for PS3 RSX IHS removal
Gonna be honest I have nothing to scrape. I bought these for the blades because they are thin enough to wedge in between the PS3’s GPU and IHS. You stick a blade in one corner in between the VRAM chip and the IHS and then tap the blade with a small screwdriver or hammer. This gently separates the old crusted thermal adhesive and should help remove the IHS with minimal effort.
