I’m a big fan of the Synology range of NAS devices. I have owned quite a few and recently had an issue with one of mine.<\/p>\n\n\n\n
A fairly recent purchase was one of the DS923+ models<\/a> however after about 6 months I have found the fans to start becoming noisy. Even though I run them with low power WD RED SSD’s so there is little or no heat AND have them using ‘quiet mode’ it was still noticable.<\/p>\n\n\n\n I can only guess that Synology have started using cheap components as this has never been an issue for me.<\/p>\n\n\n\n A quick search uncovered this thread https:\/\/nascompares.com\/guide\/synology-ds923-nas-noctua-fans-and-velcro-tutorial\/<\/a> which seemed to recomend the Noctuna NF-A9 FLX fans. I puchased some, fitted and quickly realised they are totally unsuitable<\/strong>, so dont beleive all you read \ud83d\ude42<\/p>\n\n\n\n https:\/\/nascompares.com\/wp-content\/uploads\/2024\/04\/Synology-FAN-MOD-VELCRO-MOD-DS923-DS423-DS920-DS420-DS918-DS418PLAY-DS420PLAY-33-Medium.jpg<\/a><\/p>\n\n\n\n Basically the power ratings are incorrect for what the Synology fan controller expects. The Synology ones are 0.12A, whereas the NF-A9 ones are 0.07A. If they are connected to the Synology, it thinks the fans have failed regardles of speed setting. <\/p>\n\n\n\n There was some discussion of using the pull-up resistors provided in the sets. This did not work for me and I didnt want to lash up my own lead with a 100ohm resistor inline. https:\/\/noctua.at\/en\/products\/fan\/nf-a9-flx<\/a><\/p>\n\n\n\n Also the NF-A9 ones have rubber mounts which do not allow them to be fitted correctly to the Synology. It makes the mounting bend due to them slightly being oversized. I ended up sending them back.<\/p>\n\n\n\n However, a bit more research and I found the perfect fit. The Nocuta NF-B9 redux 1600’s (see https:\/\/www.amazon.co.uk\/dp\/B0014I9K30<\/a>) are a perfect like for like fit.<\/p>\n\n\n\n

The cables are slightly long however a small cable tie sorted that.
