[SOLVED] Platform Control Hub temperature range

[Malcolm1947]

I recently assembled a new system and discovered a temperature readout in the BIOS that I'm not familiar with. Can someone please tell me whether these numbers are reasonable. System details and BIOS data follow:
 Mobo: X570 AORUS MASTER AMD AM4 X570/rev 1.0, 4 DDR4 2-CH/PCI-Ex16/ATX USB3.1/2.5 GbE LAN/M.2 socket 3 TYPE-C/7.1-CH HD Audio, SN194900003238, BIOS Version F11 (updated 02/05/2020)
 CPU: AMD Ryzen 9 3900X / Corsair H150i PRO
 Memory: Corsair Vengeance LPX DDR4 2X2X8GB (4X8:32GB) 3200MHz
 GPU: Gigabyte Radeon RX 5700/REV 1.0, GV-R57Gaming OC-8GD, PCIe 4.0 x16/8GB GDDR6/256 bit
 PSU: Corsair AX1000
 Storage: V-NAND SSD SAMSUNG 970 EVO NVMe M.2, 1TB
 Case: Corsair Obsidian 750D

BIOS readout:
CPU Frequency: 3818.54MHz
CPU Temp: 33.0 C
CPU Voltage: 0.984v
PCH: 59.0 C
Memory Frequency: 2143.74MHz
System Temp: 39.0 C
Memory Voltage: 1.212v
VRM MOS: 41.0 C

PCH is essentially the pcie routing chipset junction. All the pcie goes through it and gets routed to the cpu in an orderly and timely manner. Sorta like having half a dozen roads meet at one set of traffic lights to organize all the traffic that goes to the store. Consequently, it's an extremely busy chipset most times, so can easily hit into the 90's, as can the Sata chipset or any other stressed similar component on the mobo.

Back before the ram memory controller was moved to the cpu, the PCH was known as the Northbridge chipset.

Respectfully, your explanation doesn't answer the questions, "Are these numbers reasonable?"

I don't think those temps are out of range. I don't have that motherboard, but if you google x570 pch temp limits you will see temps around 60c.

Thanks, Kanewolf. I previously Googled x570 pch limits and went down rabbit holes that didn't help. Following your suggestion, I was more successful the second time around. Seems the PCH temp of 60c is 'normal' idle for the X570 AORUS Master.
