Hello, is your System Profile Settings on Performance?     [URL]  
PowerEdge Server R620 Rack Server Recently we are facing a strange issue on our R620 server. Normally powering on the server, it picks up machine sound and noise until in start up mode and then slows down and operate normally like it should. However since yesterday, we see that when the server is powering on, the machine sound and noise is picking up and throttle at highest thereby creating immense noise and thrust.. it feels like the server is operating at full power capacity or some boosting up at highest capacity utilizing the full power. This does not look like any hardware issue though i think some hardware configuration/BIOS/Power Config issue might prevail I've reset the server using Lifecycle Controller in Hardward Configuration for Factory default reset. Changed BIOS settings and system profile, disabled Turbo Boosting but nothing is changing. How should this be fixed?
When powering on PowerEdge R620 server, sound boosts up extremely high. How to 
Fix?
