Ketchup is the best alternative to thermal paste

Many have wondered what would happen if, instead of thermal paste, you used toothpaste or some other substance that can be found in almost every household. One of the readers of the ComputerBase portal decided to find the answer by testing various improvised “substitutes” for thermal paste, from ketchup to a piece of cheese.

Initially, the enthusiast wanted to test different thermal pads, but this also included non-standard solutions, including cheese, potatoes, toothpaste, baby cream and even ketchup. The graphics processor of the graphics card Radeon R7 240, which has a TDP level of only 30 W, served as the test platform – passive cooling is sufficient to dissipate this amount of heat. But the thermal interface is still important.

The Furmark stress test was used to generate the load and was run for 5 minutes for each thermal interface. In the case of thermal pads, only half of the tested samples coped with the task – on the rest, the GPU temperature reached 105 ° C, after which the throttling mechanism (frequency reduction) started. Copper tape failed, as did copper paste. Thermal paste performed well, as expected, and even cheap solutions didn’t allow for throttling.

Of the available household materials, ketchup proved to be the best – with it, the GPU temperature reached only 71 °C after 5 minutes in Furmark, which is roughly the same as cheap thermal paste. Even with toothpaste, there was no throttling, but here the temperature rose to 90°C. But baby cream, a thin slice of cheese, and a piece of potato couldn’t provide normal heat transfer.

Of course, ketchup or toothpaste should not be used in your computer either. At least this is not safe as they contain water and this increases the risk of a short circuit.
