Copper heatsinks on GeForce RTX 3080 GDDR6X: temperature drops by 20%

Last month the youtuber DandyWorksthrough a craft modmanaged to reduce GDDR6X memory temperatures by a lot 46 C its oneAsus TUF GeForce RTX 3070 Ti replacing the thermal pads with gods pad in rame. A really interesting solution, but not within the reach of the less accustomed to modding. To the rescue of those who want to cool down the VRAM memory of the video card comesCoolMyGPUa company that offers prefabricated custom copper plates that allow, in a simpler way, to make the mod.

The modification proposed by the youtuber involved replacing the traditional thermal pads with specially machined pads, made entirely of copper. In the specific case, the result obtained was really relevant: the operating temperature of the memories dropped by as much as 46 C, going from 110 to 64 C. Replicating that job requires a certain dexterity and skill, especially if we consider the highly conductive characteristics of copper which, if not properly insulated, risk shorting the board.

Beginners who want to try their hand at such an undertaking, will find solace by learning of the existence of a company – CoolMyGPU precisely – that makes copper heat sinks specially designed for the series GeForceRTX 3000 by NVIDIA.

The proposals are varied, but involve specific models due to the differences in the PCBs of the many partners of NVIDIA. The cost is clearly higher than that incurred by DandyWorks, but to the advantage of practicality: in the case of the RTX 3060, 3060 Ti, 3070 and 3070 Ti models, the list price of the copper plate is approximately 35 dollarswhile climbing to57 dollars for RTX 3080, 3080 Ti, 3090 and 3090 Ti models. Within the product pages it is possible to consult the list of compatible VGAs.

The CoolMyGPU solution was immediately tested by DandyWorks, interested in finding any differences between its artisan mod and the prefabricated plates. The results obtained by CoolMyGPU are quite good, with thermal performance improving by about 20% under any circumstances, from gaming al cryptocurrency mining. The test was carried out on a GeForce RTX 3080, which saw the temperature of the VRAM drop by 25 C.

It should be emphasized, however, that in both cases the product warranty will inevitably be lost, which is why the advice to “immolate” a VGA only if you are an expert user and aware of the intervention you are about to carry out. This is because once the cooling system is removed from the GPU, in the event of any problem, the cost of repair or, in more serious cases, of replacement will be entirely at your expense.
