Stop everything! Ketchup apparently makes good thermal paste for our graphics cards

Particularly exhaustive, a user of ComputerBase tested different substances to cool a Graphic card.

In addition to the classic thermal pastes, he literally played with food (and others) by testing the cooling capacities of ketchup, toothpaste, ointment or even a slice of potato.

This test was carried out on a Radeon R7 250 displaying a TDP of 30 W. The temperature readings were taken on FurMark after a stress test of 5 minutes. The results are therefore intended to be particularly specific and do not aim to demonstrate the long-term effectiveness of the various solutions tested.

However, experience offers interesting lines of thought, although their application is definitely not recommended. The user of ComputerBase shared a graphic displaying many classic thermal pastes as well as other unorthodox substances in the matter.

Among the cooling solutions for standard graphics cards, there are therefore well-known brands in the field. Arctic, Corsair and EC360 are indeed responding and posting very good results overall. In contrast, we find other far less ordinary substances such as toothpaste, ketchup and a slice of cheese. Because why not?

Another kind of thermal paste

While Arctic MX4 and Corsair TM30 thermal pastes show the best results, with 49 and 54°C respectively, some substances do almost as well as traditional products. Amasan T12 or Silber WI toothpastes stand out with honors, with temperatures of 63 and 65°C. Ketchup also seems to be a good student, with 71°C.

These uncommon substances even do better than some of the products in this chart that cause the graphics card to thermally throttle when reaching the maximum temperature of 105°C. Same observation for a slice of cheese, a slice of potato, anti-irritation ointment caused by diapers and copper paste.

The idea of ​​not wasting food or any other daily product thus finds new meaning. However, it should be emphasized that these experiments have been carried out as a hobby by the user and are not intended to be taken for granted.
