I've recently built a new system in a CM 690 ii Advanced, but im having a particular annoying noise while the PC is on, its no constant but comes and goes... A dry sound similar to a snore or the sound of when you finish a coke can and suck out the bottom with a straw. It sound like somepart doing friction with another part... a pretty common sound. Any idea/suggestion?
Open the case try to stop each fan with you finger..... press above the motor.. and listen ....is the sound come from fan.... I just build 4 system with this case last week .... and I don't see any issue..... what power supply you use...will the sound from the power supply
See if some of the wires are touching one the fans, that can be nasty, and it should not be the GPU, i have the same one and it makes a high pitched sound when with fully loaded fans, by what you described I would say HDD, it would be nice if you told us all the specs.
Cheapest way to localize sound issues in a PC:
1. Get a tube of some sort (I use the center of a paper towel roll)
2. Open the side of the case
3. Put one end of the tube to your ear and direct the other end to your different noise makers inside the case.
It may sound a bit funky but it really helps isolate noises and figure out which component is your noise bandit.
For case fans: hold them with a finger and listen what happens. For a gpu: vary the fan speed with the Catalyst software and see if the noise goes away on different speeds. For a cpu cooler: disable minimum fan speed check in your BIOS and hold the fan with your finger for a second; you could also vary the speed of it if your BIOS supports it. Harddisk: unplug it.
Some noises are hard to spot because sometimes you can only hear them with the case closed, or from a certain distance/angle from the case. In that case it's a better idea to disconnect all case fans and see what that does. If the noise stays you can start varying cpu/gpu ventilation speed. If that also fails it's probably your PSU.
My bet: it's the stock cpu cooler or your graphics card.
