The GPU has a Dual-Fan cooling system that maintains very low temperatures while performing heavy tasks. But, the noise performance is not that good. The cards’ noise was audible from a distance. I think it would be okay for some people because many PC users use headphones while gaming. The feature I think that is missing is the Idle Fan-Stop feature, which means the fan will not turn off during light use like browsing, light gaming, watching videos, etc. The power consumption of the card is also efficient. The card uses almost 135W power during Peak Gaming GTX 1650 Super.
