Dell R720XD Lower Idrac7 Fan Speeds

Table of Contents

Preface

My rack server was destroying my eardrums with the fan speeds being too high. I plan to replace the fans with Noctua's, but in the meantime this fix works great. It's not silent, but much quieter.

Commands

Run these commands inside of IDrac SSH

racadm set system.thermalsettings.FanSpeedOffset 255

That's it! Still a little noisy but tolerable.
