issue with fan and post failure problem (similar)
My setup includes: CPU – AMD Ryzen 7 7800X3D; Cooler – Cooler Master ML240L V2; RAM – Corsair Expo iCUE Vengeance DDR5 (32GB, 6000MHz); Power supply – Corsair Rm850X 80 Plus Gold; GPU – ASUS ROG Strix RTX 4090; Storage – ORICO M2 SSD 1TB, Samsung NVMe M.2 980 PRO; and a dual HDD with Western Digital Blue. I’ve used this configuration for about a year. After some time, issues arose: the motherboard displays red and yellow diagnostic LEDs, but it still boots. I ignored them initially, though after a few restarts it works fine. I investigated possible causes but didn’t resolve anything. One thing that stood out is that my motherboard has two CPU power connectors, yet I used just one. Recently, after upgrading the case and adding fans, another problem occurred. The fans I purchased are: an ARCTIC P14 Pro A-RGB, four ARCTIC P12 Pro A-RGB, a HYTE Y70 controller, and a TZMRIT fan hub. I tried adjusting fan speeds via MSI Center but couldn’t manage them. I accessed BIOS to control fans directly, but it didn’t work because the system boots straight to Windows without fast boot enabled. Recently, changing the case and adding fans led to frequent restarts before Windows loaded. If you can help fix the fan settings without entering BIOS or suggest a better controller, that would be great. I have seven fans total and want them all to run smoothly.**
To access the BIOS, press the power button, then use F1, F12, or the delete key quickly while pressing it. If the system has other issues, fans may start. Sometimes it prevents you from entering the OS.
It might not be the cause, but using two 8-pin cables would likely improve stability. Regarding the boot problem, I suspect a RAM-motherboard conflict. I experienced the same and after a clean boot, the next attempt would fail unless the system rewrote memory or updated BIOS. Beyond swapping parts, ensuring memory trains every time—though it adds a few seconds—is key. I overlooked that disabling MCR and fast boot helps. As for the fans running at full speed constantly, since installation is fresh, it may still be in DC mode in the BIOS. Adjust PWM settings via the smart fan menu. To resolve this, connect the high-power fan to a hub that supports PWM (like a hub with a sensor linked to sys_fan 1). For the BIOS, you can also reset smart settings on other fans or flash the firmware. Your X670E model should have a physical button for this—check the back. If you restart three to four times in Windows, it may enable the auto-repair feature and clear issues.
