Real achievable clock rates and overclocking
The clock rates and readout is simple this time. While the card’s GPU clock is at 2910 MHz when cold, it then levels off three boost steps lower at 2745 and later at 2700 to 2715 MHz more or less alternating after full warm-up. This can definitely be left alone. Without raising the power limit, which isn’t possible, the card also ran stably at around 2.9 GHz. More was not possible, though.
GPU temperatures in the case
The differences aren’t as big as feared if you use a proper case. If you close the panel, the GPU temperature (edge) increases by 2-3 Kelvin, the GDC hotspot increases by up to 4 Kelvin. Nevertheless, the values of around 66 °C (Edge) or up to 82 °C (Hotspot) and 73 to 74 °C for the VRAM are nothing to be afraid of. With OC, the values increase to 68 °C and 84 °C (hotspot), which still fits, but also shows that the cooler already reaches its limits.
Infrared measurements (heat flow analysis)
Let’s start with the gaming loop and we see that the voltage converters only get warm, but not really hot. The 6 phases are all positioned on one side and we remember the teardown and the VRM heatsink. Hotspot equalization and better heat distribution are not witchcraft, here it fits quite well.
In the stress test, the temperatures in the voltage regulators continue to rise, but what we just wrote also applies here. It is already quite hot, but still in the green zone. The cooling is still completely sufficient at this point. The GPU temperature remains the same (power limit!), just as the left part of the PCB gets cooler, because the fans now also turn higher and the airflow is clearly more noticeable.
