Greetings,
I have bought a Z620 workstation 1 month ago on air cooled system. I changed the original CPUs with 2x Xeon E5-2690 processors.
I found this scratchy noise wherever I change to "High performance" power plan.
Also in Passmark test --> 2D MARK - I could hear every action happening on screen by the intensity of noisy scratch. There were like 1000 images appearing fast, I could hear each of them.
Also in Passmark test --> DISK MARK - this loud and continous noise while Read and Write sequential test was disturbing.
Do you know anything on this specific problem ?
