AMD temperature/noise ratio
On these perf/noise ratio graphs, we remind you that it’s best to be positioned as far to the bottom left of the graph as possible. For reading purposes, the leftmost point symbolizes 12V ventilation, the central one 8V ventilation and the rightmost 5V.
At 65W, we note that DeepCool’s AK620 Digital is not positioned to the left, but to the right, towards the least efficient heatsinks. In these conditions, it behaves like a single-tower fan, like NZXT’s T120 RGB. What’s more, its two fans don’t do it much good in the sense that, at full speed, it’s noisier than its American rival.
At 95W, the gap between DeepCool’s model and NZXT’s widens. Admittedly, the Chinese heatsink saves the day at low revs, but this is not the case at higher speeds. What’s more, there’s a small margin for manoeuvre when it’s running at full speed – in these conditions, we can only advise you to reduce its speed!
At 150W, the AK620 Digital failed to keep our Ryzen 9 7900X at decent temperatures at low revs. What’s more, it continues to struggle against its competitors. On this CPU, it’s better to have one trick than two!
