I take it you're assuming it is silicone thermal
grease. That's
plausible.
But silicone grease only helps cooling if you stick it
(in a *thin* layer)
between the device and a suitable heat sink.
The heat sink actually does the cooling.
Ah yes. Actually there is a heat sink on the top part of the case that
sits on this chip when the case is closed. I didn't notice that.

If you
were lucky, it might overheat and set fire to your house. Then
you could claim the insurance money.
I noticed the video chip was covered with a white gunk in a couple of the
units I opened in order to reconstitute my working one. I understand is some kind of substance which aids with cooling
so that chip at least
runs very hot.
White gunk will hurt cooling, not help (white interferes with radiational
cooling).
