PC making weird vibrating noise when something is plugged into the front audio panel. - Page 2

post #11 of 15
Thread Starter 
So what could it be? Any ideas on how to fix it? Its weird because if I press on the top of the case above the disk drive the vibrating noise quiets down or stops.

It isn't your PSU, as most of the components in your PSU that are capable of vibrating would vibrate at much higher frequencies.

Just for the record.

the fact that the noise comes in waves tells me it's a harmonic noise. basically a combination of factors that is causing the case to vibrate at that harmonic frequency. having something plugged in simply puts enough stress on the frame to make the noise more noticeable.

there are a number of ways to fix harmonic noise like this and mileage varies as to how effective each method can be. as you said putting pressure on top of the case reduce the noise, so you can just set a phone book on top of your case to alter its mass/stress. changing the speed of the fans can also disrupt that harmonic vibration, sometimes it can be as simple as getting a thin strip of rubber between your HDD and HDD bracket to dampen the vibration from your HDD.

the unfortunate truth is we wont be able to troubleshoot this type of issue. you have to be at the machine to be able to isolate what the cause can be and sometimes you just have to play around with different solutions till you find one that works. problems like this are much more prevalent in cheaper cases that are made from thinner steel. it also happens quite often in aluminum cases with multiple fans installed as well, so it's not a new problem. you just have to try and isolate the noise and try different fixes. sometimes it can be as simple as a silicon gasket between your case and the fans in the case.

Ugh, the 200R is a budget case so I guess the steel is thin. I might upgrade to a higher end case like a C70 later in the future.

i'm not saying heavier cases do not suffer from this type of problems. it's just less likely since it takes a certain amount of energy to vibrate certain amount of mass. so if the case is heavier, it takes more energy for it to vibrate so it's less of a problem with heavier chassis. it's another reason aluminum chassis is also prone to this issue since aluminum is fairly light, so it tends to "hum" easily especially when multiple fans of the same speed are involved.

my old lian li used to hum like crazy at certain RPM's biggrin.gif I guess it's part of the reason why i'm not using that case anymore. even tho it's still a pretty nice aluminum case. smile.gif unfortunately, you will simply need to fiddle around with the case to see what solutions you can come up with. one of the "tools" i used to use to troubleshoot this is those 3m double sided foam tape. they do a decent job in isolating the vibration of a fan from the chassis and they are cheap to get.
