Giriş

The fan on the PSU that comes with the kit is extremely loud. This guide will go through the steps on replacing the Sunon fan that comes in the PSU with a 12v Noctua NF-A6x25.

This is not a necessary or critical mod. It simply makes the PSU quieter.

I wasn’t paid to write these guides. Ben asked me to do it as a favor to him. Considering all that he’s done for our community I felt it was the least I could do. To be honest even though it took about 2 months to build and document, I had a lot of fun doing it. It forced me to write guides in a manner that was easy for everyone to understand and cleanup my Github so I could share any files that were used that aren’t part of the original download. You’re not obligated but if you would like, feel free to donate.
