The PSU has been making noise of more than a year. The fan is supposed to be the issue. I have lost two HDDs due to the vibrations the fan brings in. Puchased a new SSD and setting up the workstation. I’m enjoying the speed 3rd Gen SSDs bring. I think anything more than this will be an overkill. The PSU fan too needs to be fixed, its annoying. The two ping 120 mm fan are rare in the online market. Have found a tiny firm accepting to ship me with a delivery time of a week. I hope this will end the misery.
