The PowerColor Hellhound RX 6600 XT positions itself between the custom RX 5700 and 5700 XT cards in terms of performance, being a considerably smaller card and at the same time consuming like half of the power from the wall. This also traduces in the need of less elaborated cooling systems to keep the temperatures in check, so the card does not weight a ton. The dual-fan solution looks cool when in operation and remains silent even at high loads. In a well-ventilated case, the temperature of the GPU should not reach 60 degrees Celsius (even when watching 4K videos), which means that in “office use” mode, the fans will mostly stay off thanks to Zero-RPM technology.
