One of the largest concerns of a large number of users about NVIDIA new generation graphics is directly linked to their energy consumption, which requires a fairly large diet, which obviously increases power, but in same time temperatures too. To avoid a problem related to the overheating of the chips that make up a graphics card, various thermal conduction systems are used between the GPU and the thermal dissipator, one of the most used being the liquid metal, although in a way RTX 5090 the difference in relation to a pasta thermal It's not that big.
Materials that allow to drive thermal energy are extremely important in all computer systems, the fact that the heat generated by a chip can be transmitted to a component dedicated only to the elimination of a large part of it is absolutely necessary in semiconductors. And as no semiconductor capable of eliminating thermal needs has yet been discovered, several techniques have been developed which use materials with good conductivity to pass this heat from one side to the other, even if some are more useful than others. , we also see that there are times when the difference is not so great.
How does the replacement of liquid metal with thermal dough affect the temperatures of an RTX 5090?
It has been almost a day that restrictions on publications related to notice of the RTX5090From Hardzone, we also have one that details all the aspects that may interest you. But there are those who wanted to do something completely different beyond showing how they work in terms of performance, and Techpowerup has taken the risk of opening it to see exactly what it looks inside, in dismantling it to show all the ins and outs of this model. .
The NVIDIA flagship card would use a thermal interface material (TIM) in liquid metal between the GPU chip (GB202) and the unified steam bedroom plate of the Flow Through double cooling solution. It is increasingly common that high -performance components use this type of material as thermal driver because they are much better than traditional thermal pasta to allow heat transfer from one component to another.
But apparently, doing this control was not enough for them, as in addition to opening the card completely, they also replaced the liquid metal with another thermal solution, using in this case the MX6 dough of Arctic, to check the temperature difference between both. material and another.
In this case, you can see on the graph that the temperature difference is approximately 2 degrees, it may not seem much since in the end we are talking about oscillating between 77 and 79 degrees, but c ' is important enough for us to see that the liquid metal is much better than the thermal dough, even if the liquid metal was of better quality, the difference could easily be 4 to 5 degrees more or less.
