our dell server is creating a loud sound continuesly also blinking red light too

Hello,

Please give us some hints. What is your server model? What is your BIOS and iDRAC firmware versions? It's very important to keep up to date BIOS and iDRAC to avoid noisy fan. But I'm not sure you addressed fan loud or something else. Which LED blinking red. blinking red light on your server could indicate a hardware failure or a critical system event. Please check system event log on iDRAC. here is the video to check SEL https://dell.to/3QskRMx. 

Hope that helps!

have you checked the IDRAC logs if not you need to check for the logs first this might be due to a fan failure in the system.
