The test system on page 2 is a Ryzen 9 9900X with an Arctic Liquid Freezer II 420. The CPU drew about 145 W by the chart. The review says the VRM peaked at just under 51 C on the reviewer's sensor (thermocouples) and 57 C on the ASUS internal sensor. The thermocouple reading is stored as 51. The exact value under 51 is not printed.
