It has spring brackets holding it down, but if you push on the side IT can move about 1 cm. You can also lift it about 1 cm.. Is there suppose to be thermal paste underneath it? should i take the HS off and apply some..
I would touch it; if it's cool, leave it alone. People can be stupid sometimes wanting to fiddle with their motherboards; these are sensitive to electrostatic discharge. Once it's in place; LEAVE IT ALONE.
