Toothpaste is also an excellent substitute for thermal paste. Its structure decays after a few days, especially if the operating temperatures are high.

What can I use if I don't have thermal paste?

The best solutions turned out to be hair wax and toothpaste, which exhibited a relatively low temperature without completely drying out and cracking. If you're impatient or under a tight deadline and need to squeeze in a few hours of extra work, consider toothpaste or hair wax when nothing else is available.

Can I use Vaseline as thermal paste?

Another solution to use as thermal paste can be obtained by mixing very fine aluminum powder with vaseline oil. The mixture must be blended for at least 10 minutes, in order to avoid the presence of little air bubbles.
