Can using toothpaste on a CPU for a week be safe?
It will function well (using no paste works too, though I wouldn't suggest it for intense gaming sessions). The main concern is how simple or difficult it is to remove after applying proper paste, and whether any parts might be harmed if it gets on them.
Toothpaste is often highlighted instead of peanut butter or Nutella because it doesn’t break down easily, staying stable over time. You only need to reapply it when it begins to dry out. Keep in mind it’s abrasive, so it’s better to wipe it away rather than scrub it, as this could cause tiny scratches on the heat sink and CPU spreader. Turning gears for a short time with toothpaste is a typical method to smooth out minor imperfections before using it properly.
You're preparing to use a PC for a week without needing to apply paste, likely due to a specific testing or maintenance scenario.
Unless your family is being held and the necessary files are on the PC, just wait a week or go shopping for them.
