Probably not. I had a laptop with similar symptom when I was compiling
stuff. I took it apart, cleaned it and thought that maybe these log
messages were normal under stress. The CPU eventually fried and only
then I took a real close look and the heatsink had a very tiny little
hole where the fluid escaped, but it was not at all apparent at first
sight. These liquid (or gel?) filled heatsinks are basically useless
if the liquid escapes or evaporates so it will usually only show when
you are using the CPU a lot.
