New Study Shows Ketchup Is Better GPU Thermal Compound Than Toothpaste

‘AssassinWarlord’, a member of the ComputerBase community, has updated a report with the addition of highly unusual products. GPU cooling is not always required to depend on pricey materials designed specifically for this purpose. In the event of a shortage of such products, GPU enthusiasts may be compelled to explore alternatives. In the most extreme situation, thermal products might need to be substituted with items from the freezer, such as ketchup or cheese slices.

On the Radeon R7 240 GPU, a ComputerBase member tested a variety of commonly used goods, from hand cream to potatoes, as heat-conducting materials. The graphics card has a power consumption of 30 watts, which indicates that it is not a particularly powerful GPU, but the TDP is easily compatible with passive cooling.

Tests have demonstrated that ketchup is an acceptable substitute for thermal compounds, reaching 71°C after 5 minutes in Furmark. Toothpaste is worse, scorching the GPU to a maximum of 90 degrees Celsius. Baby creams, potatoes, and cheese slices have all quickly reached 105 degrees Celsius, which is far from optimal for such a small GPU.

This very scientific method of thermal testing gives solutions to previously unanswered concerns. How effective would common food and bath items be as heat conductors?

It should go without saying that you shouldn’t utilise these items in that way. As demonstrated by the study, many of them may not even function with a 30W GPU. In addition, items containing water lead to the possibility of permanent GPU damage.
