Finding the finest thermal paste might be challenging, but some individuals have a greater sense of adventure than others. An enthusiast (via Computerbase) recently expanded the scope of his search for GPU thermal paste to include several intriguing items, including thermal paste, thermal pads, cheese, ketchup, toothpaste, diaper rash medication, and even potatoes.
The user’s first goal was to test several thermal pad types, but they expanded their testing to include additional materials, which resulted in an intriguing and enjoyable investigation into GPU cooling that included some materials that are not safe for long-term usage. Temperature data from a five-minute run of Furmark were taken using the test system’s Radeon R7 240, which has a 30W TDP. ,Image: Computerbase
22 distinct thermal paste selection that had been tested were included in the spreadsheet that the user shared with others. There are several common thermal pads on the list, including Thermal Grizzly Minus 8 thermal pads, Arctic TP2 0.5mm, 1mm, 1.5mm, Arctic TP3 1mm, 1.5mm, EC360 Blue 0.5mm, EC360 Gold 1mm, and 0.5mm EKWB thermal pads.
After clearing away those somewhat secure options, the user moved on to the strange materials not intended for thermal conductivity in a GPU application, such as double-sided aluminum copper tape, cheese, potato, ketchup, copper paste, and Penaten Creme for diaper rashes. The enthusiast also used a wide variety of toothpaste, some of which you may not be familiar with, such as Amasan T12, Silber Wl.paste, Kupferpaste, and an unbranded, unnamed toothpaste.
The GPU overheated, reaching its maximum temperature of 105C, and many things, including the sliced cheese and potato slices, triggered the GPU’s thermal throttling mechanism. Throttling was experienced with the EC360 Blue 0.5mm thermal pad, 0.5mm EKWB pad, Arctic TP2 1mm pad, Arctic TP2 1.5mm pad, and Thermal Grizzly Minus 8 1.5mm pad copper tape, among other thermal pads that performed poorly. The system crashed as a result of the double-sided aluminum sticky pad, which was the main culprit of them all.
The Arctic MX-4 and Corsair TM30 were the two competitors for the standard thermal paste. Unsurprisingly, with temperature results of 49°C and 54°C, respectively, both managed to keep the R7 250 at the lowest temperatures out of the group. Even if these results are as unrealistic as they come, we still don’t advise utilizing anything less than adequate thermal interface material on GPUs.
