Aliexpress GPU Backplate Coolers

AliExpress GPU Backplate Coolers Tested, Mostly Useless

Posted on

Der8auer tested two very unusual cooling solutions from Aliexpress aimed at reducing the surface temperature on the backplate of the Best Graphics Cards. However, upon testing with a Gigabyte RX 6900 XT, he found both coolers underwhelming in their execution and provided no tangible improvements to graphics card temperatures.

Backplate cooling is nothing new, but the cooling devices Der8auer showed off are very unusual, being very big and bulky devices with active cooling. This is incredibly overkill for most graphics cards since the backplate (generally) does not house any high-wattage components that would require beefy coolers. The only exception would be the RTX 3090 (non-Ti), which features half of its GDDR6X memory ICs on the rear of the card. But even in this case, passive cooling from a backplate is generally good enough unless you’re looking into memory overclocking.

The first cooling unit Der8auer tested was made entirely out of copper, comprised of two fans installed inside a copper heatsink — made out of 5 large copper sheets stacked on top of each other. The installation mechanism involved zip ties and tape to “securely” mount the cooling device to the GPU backplate.

The next device is even more strange, with a very unusual L-shaped design featuring three very long heatpipes connected to a distribution plate on one end and a heatsink on the other. Der8auer reports that instructions did not come with this model, but apparently, the device uses the same zip tie mounting mechanism as the former device since there are no screw holes or any sophisticated cooling mounts located on the device whatsoever.

In testing, Der8auer found that both cooling solutions did not live up to expectations, only dropping backplate temperatures on a Gigabyte RX 6900 XT by 5C and 8C, respectively. Even worse, both solutions did not drop GPU temperatures at all, providing no tangible benefits to GPU longevity or performance.
