ryzenRyzen problems
I recently installed an AMD Ryzen 5 3600x with an MSI B450 Tomahawk motherboard. Right after turning it on, I observed the fans increasing briefly before settling, which seemed acceptable. Once inside Windows, however, I noticed a strange fan speed pattern—fans spike temporarily and then return to normal, repeating as long as the system is idle. Additionally, the Ryzen Master temperature fluctuates between 37°C and 44–50°C during idle periods, only changing for a short time before returning to 37°C. I reviewed the motherboard BIOS and confirmed it was functioning correctly at around 30°C. The issue appears exclusive to Windows booting, while it remains stable in BIOS mode. I’m using the AMD Ryzen power profile without overclocking or extra voltage settings, and A-XMP is enabled for RAM. Any advice would be greatly appreciated.
I have temporarily fixed the problem by changing the fan curve in BIOS to maintain a steady 30% speed when temperatures drop below 60 °C, which stopped the random increases. However, in Windows all tools continue showing incorrect and inconsistent readings. Is this related to Windows, because in BIOS it works normally?
It's strange that the CPU temperatures appear to rise sharply to around 60 °C for a brief moment, then quickly fall back to about 40 °C. I believe this pattern triggers the fans to speed up temporarily to manage the high temperature before slowing again. It's confusing and a bit concerning.
I reduced the disturbance by adjusting the fan curve in bios to remain steady below 65 °C (the maximum I've observed in reports). At roughly 30% speed, it works well for tasks that raise temperatures above 60°C, after which the fans increase appropriately while staying consistent until then. It hasn't completely solved the issue—I still hear them rev every few seconds, though they're quieter now.
