Though it has been confirmed that the Delta varient of the Steam Deck contains the whining fan noise, and though iFixit is trying to secure replacement fans, there’s a relatively easy fix that you can do right at the comfort of your own home, and chances are you’ll already have it available: electrical tape. A Redditor made a post about it. They recorded before and after the fix. All they did was take the back plate off the Steam Deck (just eight screws) and put some electrical tape behind the Valve logo.
