The CPU cooler isn’t fitting properly.
The CPU cooler isn’t fitting properly.
Of course it won't - you need to separate the two & reinstall the CPU correctly... if you still can, that is.
Usually you remove the CPU from the cooler when it's stuck. First place the CPU into the socket, then position the cooler on top since the retention arm can't go through the cooler.
That's a better idea, but it doesn't seem like a standard way to mount a CPU or cooler.
It also indicates they removed it using the same method... In other words, it's possible to do that.
