The Ryzen temperature readings may not be correct out of the box.
The Ryzen temperature readings may not be correct out of the box.
Upgraded with a Ryzen 1700 8C/16T and specs, Ryzen Master at 3.2ghz, 1.1875 reads around 63-67°C during The Division and multitasking with some browser tabs, a VoIP call, and streaming. Performance may fluctuate depending on external combat intensity versus relaxing inside a safe zone.
After diving deep into the Google rabbit hole following an unusual issue where the CPU didn’t downclock while idle after an OS update via BIOS, I noticed many others—like my Abc250 Pro4 with ASRock MMO and some other models—were able to achieve this by using Ryzen Master instead of the BIOS. Even when the BIOS was quiet and silent, the system wouldn’t downclock. However, with Ryzen Master, it would downclock smoothly during idle when updated.
I reported seeing up to 1.35v at 3.8ghz reaching around 81°C max, usually around 75°C during gaming with the stock cooler. Online I found a Reddit thread pointing out that AMD’s temperature readings aren’t always accurate, sometimes showing a 20°C higher than actual.
Is it accurate that there’s a -20°C difference? For example, if it’s 65°C during gaming, my true temperature might be around 45°C? It’s strange how this has persisted over the years. I recall reading back then that even on older CPUs like the Bulldozer or Piledriver, temperatures weren’t reported correctly.
Regarding using the stock Wraith Spire cooler, it seems reasonable to assume it would perform well given the readings. Still, it would be interesting to see the true temperature displayed by the stock cooler. Thanks for any advice—I’m still getting used to this new build, which is quite different from what I was used to before.

The main temperature reporting sensor for the AMD Ryzen™ processor is known as “T Control,” short for tCTL. This sensor comes from the junction (Tj) temperature, which connects the die to the heatspreader, but it can be adjusted in certain models so that all AM4-based CPUs share the same maximum tCTL value. This method helps maintain a uniform fan policy across all AMD Ryzen™ devices. Typically, it registers about 20 degrees higher at tCTL.
I’ve discovered that HWInfo64 works well and accurately reads tDIE on this platform.
Regarding overclocking, the Ryzen master isn’t the most reliable method. It’s better to rely on the BIOS settings, as they offer more control if problems arise and your configuration doesn’t meet expectations.

Regarding overclocking, the Ryzen master isn’t the most reliable source. It’s better to rely on the BIOS settings. If problems arise and your settings aren’t working as expected, BIOS corruption might occur. While a BIOS flash can fix some issues, others have had to reinstall the operating system entirely.
At 3.8GHz with 1.35V, the core reaches 61°C at the sensor tDIE – an ideal balance.
