I started using Closeup tooth paste as a thermal paste just now, and the temps have plummeted from 47 down to 33 degrees celcius.

I still have to observe it a little more and then I'll tell you the results.

Have you guys tried something like this before?

Mayonnaise is a decent TIM because it's half oil, at least for two days:

Toothpaste isn't too good when fresh (better than only one commercial paste above), and it's water-based so deteriorates by 12 hours. The vegetable oils oxidize rapidly into not-as-effective and hard-to-remove varnish (not to mention the eggs in mayo!). Obviously the chocolate burns into carbon right away.

So the moral is if you need some emergency substitute paste, to use some type of mineral oil based grease such as wheel bearing grease, anti-seize, Vaseline or even the tested lipstick.

Have you not read the multiple tests of junk like this?
Give it a day or two until it funks up.

Your temp went down because 'new', not because toothpaste is 'better'.

I can't vouch for Close-Up as an effective thermal paste but I do know that
Crest has been shown to be an effective decay-preventive dentifrice of significant
value when used in a conscientiously applied program of oral hygiene and regular professional care.

Crest can also be used as spackling for small holes and is wonderful for cleaning and brightening diamonds
and gemstones in gold jewelry.

No, do not use that. As it says on the page...

Permanent adhesive

That particular product is a two-part epoxy intended for permanently attaching heatsinks to components that lack other means to hold them in place, and should not be used for CPUs. Put that on your CPU, and you'll likely never be able to remove your heatsink again.
