Water Pump Header (X370)

Keep in mind that AMD has always had a goofy way of reporting temperatures. On my board (x370 Gaming Pro) there are two main temps I look at under HWINFO version 5.47-3125: Tctl and Tidle. The Tctl value is the reading that AMD outlined as reading 20 degrees Celsius higher than the actual temp on 1700x and 1800x for some goofy fan profile difference they implemented on those CPUs. So take that and subtract 20, you'll be close to what it really is.

That's the Ryzen "temperature offset" of 20° C AMD has programmed in for use with their stock CPU coolers. That really seems to be for future use with the four core processors, that have a lower TDP than the eight core models. I'm not 100% sure what temperature is shown in the UEFI, HW Monitor screen, but my best guess is Tctl.

I see the same thing in HWiNFO64, and I love the way it is programmed to show both! The ASRock utility for X370 Ryzen boards (A-Tuning, etc) will show the Tctl temperature you see in HWiNFO64, it matches it perfectly.
