Temperature curve of the GPU

A direct comparison between gaming and torture load clearly shows how different the GPU temperatures are. In gaming mode, the thermal load in the practical scenario is at a moderate level, so that the temperature curve levels off at just under 60 degrees Celsius after an initial rise. The differences between gaming and OC BIOS are marginal, the line only fluctuates slightly because the real gaming load brings with it a certain dynamic.

In Torture Mode, on the other hand, the constant synthetic load feels like a constant test of endurance. Here, the GPU reaches a stable final value, which is still comparatively low at around 62 to 63 degrees Celsius in Gaming BIOS and just under 62 degrees Celsius in OC BIOS. It is noticeable that the curves in the Torture test are much more even than in the gaming scenario, as there are no load peaks or load relief.

All in all, the comparison shows that the cooling of the Galax RTX 5070 Ti Hall of Fame offers sufficient reserves even under extreme conditions. In everyday gaming, the temperatures are in the mid-fifties to upper fifties, while under full load in the Torture test, the 60-degree mark is only slightly exceeded. This proves that the card’s cooling design and fan control work reliably even with a permanent power target and that there are no thermal bottlenecks to worry about.

Memory temperatures

A comparison of the memory temperatures between gaming and torture load shows a clear picture of the thermal design of the Galax RTX 5070 Ti Hall of Fame. In the gaming loop, the GDDR7 modules reach temperatures between 63 and 66 degrees Celsius quite quickly, regardless of whether gaming or OC mode is active. Both BIOS variants are almost identical, which indicates that the memory chips are hardly loaded differently by the GPU’s power target in realistic gaming scenarios. It is only noticeable that the values in the gaming test stabilize on a slightly higher plateau, which is due to the more variable load with more intensive bandwidth peaks. The memory reacts more strongly here to the sometimes irregular accesses of modern game engines, which cause continuously high memory activity.

In the Torture test, on the other hand, the temperatures settle lower, in the range of 57 to 59 degrees Celsius. This is where the synthetic load comes into play, which is more evenly distributed and generates fewer extreme values during memory accesses. As a result, the thermal load is somewhat lower and the cooling system can dissipate the temperature level more easily. Even in this scenario, the differences between gaming and OC mode remain marginal, which proves that the adjustment of the boost offset almost exclusively affects the GPU, while the memory operates unchanged at 30 Gbps.

The comparison thus shows that the memory cooling of the Galax RTX 5070 Ti HoF does its job very well. Even under demanding gaming scenarios, the GDDR7 memory remains well below the critical 70-degree mark, and the level is even more comfortable in the synthetic endurance stress test. This is a clear advantage for long-term operation and ageing resistance of the modules, especially as the modules would react more sensitively at higher data rates.

Thermography

The thermographic images taken with the Optris PI640 allow a very detailed view of the thermal load on the RTX 5070 Ti HoF. The camera works with a resolution of 640 × 480 pixels and a measuring range of -20 °C to 250 °C. The accuracy is typically a maximum of ±2 °C or ±2 % of the measured value, so that the temperature distribution on the components can be reliably displayed. As the emissivity of electronic components is taken into account, deviations in the range of a few degrees can occur, but these are insignificant for the evaluation of relative temperature differences, especially as identical conditions prevail during direct comparison.

In idle mode at a room temperature of 20 °C, the values are at a very low level. The GPU socket stabilizes at around 35 °C, the memory chips are at 35 to 36 °C, while the VRM areas remain just below 40 °C. The 12V2x6 connection also shows no abnormalities at around 32 °C. This means that the card is practically inconspicuous thermally in idle mode, which indicates an efficient base cooling design.

In the gaming loop with the gaming BIOS activated, the temperatures rise significantly, but remain within a safe range. The GPU is in the range of just under 60 °C, the hotspot measurement shows around 63 °C, and the memory chips are around 57 to 58 °C. The VRM voltage converter areas (VDDC) reach around 61 °C. It is noticeable that the heat distribution remains homogeneous, with no extreme hotspots outside of the GPU vicinity. The 12V2x6 connector also heats up to around 50 °C, which is within reasonable limits, but would be the most critical point under prolonged load, as cable transitions are more thermally sensitive than silicon.

The OC loop with increased boost offset, but identical power target, shows a very similar picture. The GPU temperatures are around 59 °C, the hotspot slightly lower at 62 °C. The memory chips remain slightly cooler at around 55 to 56 °C, and the VRM zones are also slightly below 60 °C. The 12V2x6 connection also remains practically the same at just under 50 °C. The decisive difference is the more even temperature distribution for the GPU and VRM, which is related to the somewhat more constant power consumption in the OC BIOS. The stability of the values indicates that the load is distributed more dynamically without putting additional strain on individual components.

The interim conclusion is therefore: The cooling of the Galax RTX 5070 Ti HoF is thermally very well designed both in idle and under gaming and OC load. GPU and memory remain well within the green range with values around 60 °C, even in OC mode. The VRMs are in the normal operating window at around 60 °C and therefore still offer reserves. Only the 12V2x6 connection reaches values of just under 50 °C, which should be kept in mind during long-term operation. Overall, the thermography shows that the cooling works homogeneously, the components are loaded evenly and there are no critical hotspots even in OC mode. But what happens during the stress test and permanent continuous load?

In the stress test, the thermography of the Galax RTX 5070 Ti Hall of Fame shows very well how the temperatures develop under a uniform continuous load and remain almost congruent in the comparison between gaming and OC mode. It is noticeable that the 12V2x6 connection shows a stable but still completely uncritical temperature rise of around 51 °C, which speaks for a clean contact. The memory chips are at 56.5 °C in gaming mode and 55.9 °C in OC mode, which is practically the same. The other measuring points, such as the VRM rail (around 62 °C) and the VDDC traces at just over 61 °C, also show only marginal differences.

The GPU socket is at a very similar level at 60.6 °C in gaming mode (top image) and 61.7 °C in OC mode (bottom image), while the hotspot area records the highest load in both modes at 64 to 65 °C. This means that the card remains in an absolutely uncritical thermal range even under maximum synthetic load. Compared to the gaming loop, the temperatures are slightly higher and more evenly distributed, but the differences between gaming and OC mode remain minimal. This shows that the card’s cooling system is also able to dissipate the additional load of the higher clock offset in OC mode without any problems.

As an interim conclusion, it can be said that the Hall of Fame only reaches moderate temperatures that are far from critical thresholds in all relevant areas, despite a massive continuous load. The cooling works in a balanced manner and the thermal differences between gaming and OC mode are so small that they should have practically no influence on long-term stability.

Special features of the board in terms of heat flow and hotspots compared to the MSI RTX 5070 Ti Vanguard

This clearly shows how differently the two designs work. The Galax RTX 5070 Ti HoF distributes its waste heat very evenly across the entire board. The thermography above showed that the GPU socket region is around 60 to 61 °C in OC mode, the VRM areas around 62 °C and the memory chips between 55 and 57 °C. The hotspot is only just above 64 °C. This means that the entire card remains within a narrow temperature range, without any extreme hotspots. The reason for this lies in the board design: Galax relies on significantly more voltage converter circuits, which are distributed more evenly across the entire board. This reduces the load per phase and distributes the waste heat better. The currents also run over wider and multiple redundant traces, which reduces the power loss in the tracks and allows the GPU a higher power budget.

The MSI Vanguard in the identical Torture loop (picture below) is completely different. The temperatures there are much more uneven. While the GPU socket is just under 67 °C, the hotspot rises to almost 83 °C. It is even more pronounced with the VRMs, which reach over 72 °C, and the PWM memory controller, which climbs to over 77 °C. This shows that although MSI has also implemented a strong power supply, it is less finely distributed. Fewer, but more heavily loaded phases generate more waste heat at individual points. The layout concentrates the power loss and creates typical hotspots that stand out like islands in the thermography.

Another aspect is the fans. Galax allows the fans of its HoF series to rotate somewhat more aggressively. Although this subjectively generates more noise, it leads to a more constant dissipation of waste heat from the heat sinks. In combination with the homogeneously distributed board design, this results in an evenly tempered board that not only works cooler, but is also more gentle on materials. The bottom line is clear: the HoF benefits from its extremely complex PCB design and the high number of voltage converter circuits. This prevents local overheating and ensures even temperature distribution. The Vanguard, on the other hand, shows typical weaknesses of a more compact layout, where certain areas are subject to significantly higher loads. This not only affects the cooling performance, but also the durability of the components concerned in the long term.
