The location of your cooling screw is also starting to wear, mine was worn by the spring screw and I replaced it with the manufacturer under warranty. I recommend using a special thermal plastic washer under the spring screw. I got a screw from the manufacturer. Complete screw set for the X170 model and separate CPU and GPU cooling spring screws. I think it's still available. Write to the manufacturer! The German Clevo XMG/Schenker was closer to me and I bought it from them. Good luck!
