Now that my Steam Deck LCD has been relieved of his duties as a daily driver desktop PC, I finally went ahead and replaced the Delta fan with a Huaying one. It turned out to be relatively easy to do ; and lo and behold, it is indeed quieter.

Recent adopters may or may not know there was a medium-sized kerfuffle about disparities in noise profiles of early Steam Deck units. It was proved and narrowed down to a difference between 2 fan models (see Gamers Nexus detailed analysis).

Obviously the one I got was a “bad” one, emitting a high pitched noise when running at full speed. I did not find it unbearable but it was still not ideal, particularly when using the SD in quiet environments.

Took me 2 years to get to the point where I figured it was an acceptable risk to attempt the replacement. How many of you did the same and kicked the Delta out of your unit ?
