Just slice it off, if you take too much off it just takes a few more days to re-grow.

If you can't see the screen, it needs to come off.

Ok so you just stick it on

[kotlec]

1.Use special glue like "arctic silver"
2. or bolt it down using bolts.Use heat transfer silicon paste.
3. or use special double sided heat transfer sticky pad (or what ever its name)
