Methodology: temperature tests
The biggest hardware changes compared to non-Super cards concern the GeForce RTX 4070 Ti Super. What’s different is the GPU, the amount of GDDR6X memory or the width of the memory bus. We have the RTX 4070 Ti Super in one of the cheapest non-reference designs, the Ventus 3X, for analysis and it will be about “reputation repair” as well. MSI has tarnished it a bit in this line of graphics cards in the past, but now it’s a very attractive solution.
Methodology: temperature tests
We’re also bringing you temperature tests. You are at HWCooling after all. However, in order to make it sensible at all to monitor temperatures on critical components not only of the graphics card, but anything in the computer, it is important to simulate a real computer case environment with healthy air circulation. The overall behavior of the graphics card as such then follows from this. In many cases, an open bench-table is inappropriate and results can be distorted. Therefore, during all, not only heat tests, but also measurement of consumption or course of graphics core frequencies, we use a wind tunnel with equilibrium flow.
Two Noctua NF-S12A fans are at the inlet and the same number is on the exhaust. When testing various system cooling configurations, this proved to be the most effective solution. The fans are always set to 5 V and the speed corresponds to approx. 550 rpm. The stability of the inlet air is properly controlled during the tests, the temperature being between 21 and 21.3 °C at a humidity of ±40 %.
We read the temperature from the internal sensors via GPU-Z. This small, single-purpose application also allows you to record samples from sensors in a table. From the table, it is then easy to create line graphs with waveforms or the average value into bar graphs. We will not use the thermal camera very much here, as most graphics cards have a backplate, which makes it impossible to measure the PCB heating. The key for the heating graphs will be the temperature reading by internal sensors, according to which, after all, the GPU frequency control also takes place. It will always be the heating of the graphics core, and if the sensors are also on VRAM and VRM, we will extract these values into the article as well.

- Conclusion
Even number of blades are usually avoided in PC fans due to it negatively affecting noise, but MSI has decided to use 10 blades here… but in pairs of 5. Perhaps that’s why they opted to connect blades in pairs instead of making a full ring, so that there’s an odd number of repeating units. Really interesting design.
