The 12V rail’s OCP triggering points are correctly set, but this is not the case for the minor rails where the corresponding OCP triggering points are set sky-high. To make matters worse, the difference between normal and hot temperatures is minimal, and at 3.3V, instead of OCP dropping, we noticed an increase!
The Over Power Protection is properly set, but this is not the case for “PWR_OK inactive to DC loss delay,” which is 0ms, while it should exceed 1ms. Moreover, I expect any modern high-end PSU to have fan failure protection.

I read that ball bearing fans become significantly louder over their lifespan, so they’re deceptive in terms of noise. Is that true? Also, I read that if they’re dropped they can be ruined, so they’re more delicate than FDB fans. It seems like a no-brainer to exclusively use FDB fans in high-end PSUs. Ball bearing fans appear to be able to produce more static pressure than other fan types but since FDB fans apparently can be used in low-noise PSUs, it seems that that advantage isn’t enough to outweight the drawbacks.
With not high quality DBB fans yes this can be the case.
