Did you use thermal paste when replacing the heatsink ?
*******
This document is to demonstrate someone applying paste to their
processor. Just to give you some idea how it works. It improves
thermal conductivity into the heatsink/heatpipe assembly.
Enthusiasts use paste, because they're always taking their
computer apart, and this stuff is relatively easy to clean
off and easy to re-apply.

Some heatsink assemblies come with thermal tape, which is good for
one application. And tape has about 1/10th the performance of paste.
The advantage of tape, is it never needs maintenance, whereas the
same cannot be said for thermal paste. You may need to disassembly
and reapply paste after a several year period. (I.e. If three years
from now, it's shutting down again, you may need to clean and reapply
some paste.) I haven't changed the paste on mine since installing it
a couple years ago, and thermal performance is still good. With tape,
it wouldn't conduct nearly as well, but the tape can't "ooze out"
of the gap.
If your heatsink assembly did come with thermal tape on it, the tape
can have a protective layer on the outside, which you remove.
I really hate that concept, because on a few occasions, I peeled
off the wrong layer, and ruined the tape. So if your heatsink
assembly came with tape, make sure you're prepared the thing
properly before bolting it down. You may have left the
protective plastic on top of the tape. If you did it right, the
active surface would be sticky or gooey, rather than being "smooth"
like plastic. The plastic cover, is to prevent the material underneath
from picking up dust and dirt before usage.

Some heatsinks, like on desktop processors, come with screen printed
material. The heatsink is suspended in a plastic shell, so the gooey
material won't touch anything until you're ready to use it. So that's
how they avoid using a protective cover in that case, by suspending the
heatsink so it won't touch anything.
In this example of a desktop cooler, you can see a gray material that's
been printed or deposited, on the aluminum. It's ready to press down
onto the CPU, with no additional preparation steps.
