White gunk will hurt cooling, not help (white interferes with radiational cooling).
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.

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 this
is some kind of substance which aids with cooling so that chip at least
runs very hot.
