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 ?
Replaced the Delta for a Huaying as soon as I could, ifixit kept being out of stock, but I managed to snatch one earlier last year, it was scary, and removing the backplate felt like i was going to break everything, but the insides are well organised, it was quite an easy repair / replacement
I couldn’t live with the hiss of the Delta, it was driving me insane
