Once the power virus is applied, power draw quickly jumps to around 340W, with temperatures gradually rising alongside it. It takes roughly three minutes to reach a steady state, where both the GPU die and memory stabilise at around 60°C for the remainder of the test. Fan speeds follow a slower curve, steadily ramping up over the 20-minute run.

Initially, the fans spike before settling at around 550 RPM, then gradually climb to roughly 1150 RPM—about 66% of their maximum speed. Once the load is removed, the fans shut off almost immediately, and within 30 seconds, the heatsink is left to dissipate the remaining heat passively.

That said, even after five minutes back at idle, temperatures don’t immediately return to their starting point and require a bit more time to fully settle. Still, acoustics are excellent. Even under load, the fans are barely noticeable, with most of what you hear being general airflow through the case rather than the fans themselves.
