Loud Lynx

Hello,

I've not even had my Lynx for a full 2 weeks, but I have had an extremely frustrating buzzing/vibrating/humming noise coming from it. I spent about an hour on the phone with tech support, and while the guy was great, we were unable to solve the issue. He said he would speak to his colleagues to see if they have any ideas, but I am frustrated enough to make this post as it is hard to enjoy my PC while it's making irritating noises constantly.

I was so positive when I opened the ticket that it was one of the front 3 fans, as that's where the noise is heard the loudest. When I use the Digital Storm remote to turn the fan speed up and down, the noise varies in annoyance level and the sound. Sometimes it's a buzz, and other times it sounds like a fan hitting something. HOWEVER, even after stopping all the fans in the system (aside from the PSU fan), the buzzing noise remains.

Here's what we tried:
-Turning off all the fans individually (aside from PSU)
-Turning off the exhaust fan and the 3 front fans together
-Cutting a loose zip tie near the fans
-Ensuring that all other wires are away from fans

None of this altered the noise coming from the PC.

The annoying noise is only gone if I have the fan speeds at the highest setting regardless of whether or not the fans are spinning, but of course that creates a different noise issue since the fans are on full blast.

My wife got almost the exact same build delivered a couple of weeks prior (with the only difference being the GPU), and hers is ultra-quiet. When I first turned on my PC I immediately noticed the noise, in stark contrast to when we first turned hers on and heard nothing.

Please shoot any ideas my way!

One more fan to consider is the fan inside the power supply, and also the fan on the video card. I'm not sure how you could test those fans though. Maybe you could watch them using a bright flashlight, and see if you can detect any change in those fan speeds when your are doing your sound tests.

I appreciate your input. I turned the PC on its side and listened closely to the PSU fan to see if that was the culprit and I didn't hear anything. The only time it is not buzzing is when the 3 front chassis fans and the exhaust fan are all turned off.

This is a strange problem... I had a similar problem as what bprat22 described in my previous DS system. After many years of quiet use, my system developed a noisy buzzing rattling problem...would start right after start up and sometime go away. I localized it down to the top fan...but the fan was quiet if I pulled it out and ran it outside of the case. I found one of the screws / offsets failed and it would not let the fan sit tightly in the case...if the RPMs hit a certain amount then the buzzing / rattling noise would happen.

I think you may have something loose in the case that is keying off the vibration of fans connected to the case / chassis in some way. Try removing the fans one by one and see if you can localize the issue.

Good luck!
