Temporary heat-sink compound (Thermal Grease/Thermal compound/Thermal Paste)
This thermal grease is made up of toothpaste, preferably mint (I used Colgate toothpaste) and petroleum jelly. The ratio should be around 3/4 toothpaste and 1/4 petroleum jelly. This compound is only a temporary thermal compound where it is not as effective as transferring heat from chip to heat-sink like thermal pastes with synthetic silver compounds. You can use this Diy paste until you get your proper paste, or just use this paste only on low power devices. I would warn NOT TO USE THIS CPU OR SENSITIVE DEVICES, AS THIS MAY RUIN THE DEVICE. I've only used this on power Mosfets, transistors and high power 1-3 watt leds, and it works fine.
Above, in the picture, is what the compound would look like, it doesn't look pleasant, but its going to be covered by the device or IC.
When finding a heat-dink compound for CPU's or sensitive devices, use high quality compound like
Arctic Silver 5 or other compounds, don't use this Diy compound.
I AM NOT LIABLE, IF YOU DAMAGE YOUR SENSITIVE DEVICE WITH THIS DIY THERMAL COMPOUND. DO IT AT YOUR OWN COSTS/RISKS.
