The temperatures of the fast video memory on Ampere graphics cards can be tamed with copper pads.
The temperatures of the GDDR6X memory can be tamed with simple copper pads.
With each graphics card generation, the clock rate of the video memory used increases. At the same time, this causes the VRAM to heat up. In the case of the GDDR6X memory used on current Nvidia Ampere GPUs, the temperatures rise to over 100 degrees Celsius. The modder Dandy Works therefore started an attempt: he wanted to cool the heated GDDR6X chips with copper pads. The result is convincing: instead of 110 degrees Celsius, the VRAM chips can be cooled down to 64 degrees Celsius.
Temperatures of over 100 degrees Celsius are not a real problem for the GDDR6X memory, they are within the specifications. Nevertheless, such a strong reduction in temperature is desirable, since this means that temperature-sensitive components in the vicinity of the chips are less stressed and, at the same time, the fans also have to work less quickly and loudly. Dandy Works used an Asus Geforce RTX 3070 Ti TU for his experiments. Normally thermal pads are installed on the VRAM chips. The cost of the conversion is manageable, a pack of 40 copper pads is available on Amazon for $13. However, it is important to consider the thickness of the pads. In addition, the conductive pads must be electrically isolated with a tape.
Test under extreme conditions
Anyone who is fundamentally confident in the conversion will find many tips in the video by Dandy Works. It should be noted, however, that the heat reduction from 110 to 64 degrees Celsius was measured when mining a cryptocurrency with 100 percent fan speed. Correspondingly different values could occur in everyday use or when playing games.
RAM for graphics cards is becoming significantly more expensive
