Just to clarify, I made a mix using 75% toothpaste and 25% vaseline, and put it inside a syringe.
I then put a dot of it on the CPU after cleaning off the old paste using rubbing alcohol, with a lint-free rag.
After that, I used both the rag and the heatsink bottom to spread it out evenly.
I see no issues, and this is just until I can get actual thermal paste.
Locking because everyone is going to yell at me like I'm a loving MIT guy who is 25 years old.
