Let us now turn to the practical implementation. With the “Air Tower Cooler” setting, theoretically up to 288 watts are possible, but in the end not quite that much was needed. I left all values @Stock and played with the AC/DC Load Line alone at first. I take here as the highest value 80/80, which I also had in the launch on the MSI MEG Z690 Unify (default). After that, it gradually goes up to 40/40 as the most economical option. The wattage numbers are slightly higher than with a cut to 241 watts, but that’s marginal. I just want to understand where the high power consumption and heat comes from.
The temperatures fall with the mOhm. After all, there is a temperature difference of 26 °C between both limits. With a normal AiO (be quiet! Pore loop 240 + LGA 1700 kit) the values go up another 10 degrees and the CPU almost scratches the 100 degree mark at 80/80 and 254 watts. However, at 70/70 you are already below thermal throttling in any case. That’s also a realization.
And now let’s take a look at the CB score, which I actually don’t like as a benchmark. To make it at least somewhat useful, I used an average of 3 iterations. We see that 70/70 is barely slower than 80/80 and I even had a run that was significantly faster but later disappeared in the average. This is exactly why I don’t like CB as a benchmark, because a single run can never give consistent results. But from 60/60 on you also notice the decreasing performance, because the real clock rates also drop and at 40/40 the result even almost halves. However, we also see that the slump is not entirely linear, but is initially less severe than expected.
The voltages read out also show the influence on the final power consumption and thus also the temperature development. Before you start manually undervolting by lowering Vcore, I would first try the 70/70 setting for the AC/DC loadline. If you have a good CPU, you shouldn’t have to suffer any performance losses, but you will be rewarded with a more frugal and cooler system.
On the next page you can read how this works with the VF curve, which is used here.
