Real achievable clock rates and overclocking
The clock rates and the readout are simple this time. While the GPU clock of the card is at 2910 MHz in cold state, it then levels off three boost steps lower at 2760 and later at 2685 to 2700 MHz more or less alternating after complete warming. You can definitely leave that alone. Without raising the power limit, which is not possible, the card still ran stably at around 2.9 GHz. However, more was not possible.
GPU temperatures in the case
The differences are not as big as feared if you use a decent case. If you close the panel, the GPU temperature (Edge) increases by 2 Kelvin, the GDC hotspot increases by up to 4 Kelvin. Nevertheless, the values of around 65 °C (Edge) and up to 78 °C (Hotspot) and 80 °C for the VRAM are nothing to be afraid of. With OC, the values rise to an ample 66 °C and 79 °C (hotspot), respectively, which still fits perfectly, but also shows that the cooler reaches its sensible limits here.
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 8 phases are 8 phases and we remember the teardown and the VRM heatsink. Hotspot equalization and better heat distribution are not witchcraft, but cost extra.
In the stress test, the temperatures in the voltage regulators continue to rise, but what we just wrote also applies here. The cooling is still completely sufficient at this point. The GPU temperature stays the same (power limit!), just like the left part of the PCB gets cooler, because the fans now also spin higher and the drafts are much more noticeable.
