Hi guys, first time poster here. So I recently put together a system for the first time. Everything was running great. I just added three case fans to my pc and now it makes a beeping noise. I have the NZXT Phantom 410 case with the built in fan controller. Here is the kicker. It only makes the beeping noise on the 2nd (middle) speed. On low and high speed it runs fine, no beeping, no problems. But when I set it to the middle speed, it makes a continuous beep. I can't tell where its coming from but it must be connected to the fans. All fans are spinning and all are connect to the fan controller via the 3 pin plugs, ie none are connected to the motherboard.
Oh, and I also swapped out my old graphics card for the gtx670 while I was adding the fans but I cannot see the problem being with the gpu.
Please help me

This seems to be the exact problem I am having. Seems to be related to a faulty fan controller. Looks like I'll be contacting NZXT customer service. I heard they are not the best. Any truth?
In the meantime before I get my replacement, maybe I can plug my new fans into the motherboard and that will eliminate the noise? Because before I installed the new fans it was working OK on medium. Could there be a conflict between the NZXT fan controller and my Cooler Master SickleFlow fans?
