So my problem is I wanted to clean out the dust from a computer. I unscrewed the fan, took off the brackets holding down the heatsink, pulled on it and out came both the cpu and the heatsink. The stuff on the cpu isn't thermal compound, looks like some type of adhesive, so I can't put the cpu in with the lever in the up position. Anyone have any experience with this or am I missing something. Any advice would help at the moment as this isn't my pc. I don't usually use adhesive and from my understanding, the heatsink isn't going to come off no matter what. It might have been broken before I looked at it because of a flood, but I still want to get the cpu in there and try it out.
