San Ace 109H101 rattling with fan controller?

post #1 of 4
Thread Starter 
Hi I recently acquired 2 San Ace 109R1212H101 fans, they perform great but when I hook them up to my NZXT Sentry Mix fan controller they both make a rattling noise at all speeds. This is not the case when they are plugged into my case's inbuilt fan controller or off a molex plug. No other fan I own does this :s

What is the issue?

I had this issue on a Cooler Master PWM fan a while ago. The fan bearings went bad which caused the rattling noise for me. I hate to say this but those fans may be faulty. worriedsmiley.gif

I hope this helped! biggrin.gif

Thanks for posting. However, if they are faulty then why do they not make the rattling noise when plugged straight into the PSU or my case's inbuilt controller? The problem arises when they are connected to the NZXT fan controller.

Hm, this I do not know. Maybe you're overpowering the fan? I have never used a fan controller before so I wouldn't know.
