Hi folks,

I recently bought Zalman ZM-MFC3 Fan Controller and two Corsair AF120 Performance Edition fans. My CPU fan and other chassis fans work alright connected to the controller; The problem is, when I plug the AF120s to the fan controller they just repeatedly stop and restart, and the controller shows 0000 as the RPM value of those fans.

Now, the user's manual says "Fans with a specified minimum RPM may repeatedly stop and restart, but this is not a defect of the ZM-MFC3. Please set the RPM above the specified minimum RPM of the fan". Well, I even maxed out the RPM but no luck, no matter what I do the RPM value stays at 0000. Anyone tried these fans with a fan controller before? Is it possible that they lack the RPM output function?

PS: All connections are properly done.

Thanks in advance!

Those fans are a constant RPM fan, meaning they are designed to run at one voltage. This could cause some issues when hooking them into a controller since you aren't always running them at the power they were meant for. I know my fixed RPM Xigamtek Fan has issues when hooked to my NZXT Sentry 2

IT could be the controller is defected or that the fan is defected. Best bet would be to find another fan, or buy a real cheap one and test it on the controller. If it has the same issues then the controller is likely defect.
