Hello. I've recently built the pc in my sig and I'm having what could be an issue? Not sure. I'm hearing a popping sound not too frequently in side my computer. Maybe 1-2 times per day. I read up on this problem online and so far I've seen it can be motherboard conductor capacitors thingies being burnt, those small cylinder-shaped metal pieces on the mobo, and they AREN'T burnt or anything since I opened the case and checked.
I also read it could be about HDD failure but my 2 HDDs are running flawlessly. My SSD is fine as well if it matters.
edit: I also want to add that my case on the back (NZXT Phantom Black Case) has many cables. A 24 pin, 8 pin, etc.. I was cable managing and just stuffed the cables on the back of the case. I closed it and of course the case didn't close easy but it did close completely. The upper left corner of the case just comes off slightly. Some of these cables are against a grill for air flow on the back side of the case so maybe these cables being constricted down may cause the sound? I'm just thinking of anything at this point. Here's a picture of the cables and the fan grill.

Update: Happened a good 2-3 times today, it's getting more frequent, not too much though but it worries me it might be something far more serious.
Like I said before there is load on the back of the case with the cables, see how the fat 24 pin PSU -> Motherboard connector is in a twist, could that be causing the pop noise if it's pushing the back of the case? Here's a picture:
Now it popped in one place and seemed to quickly pop in another place near the top of my fan, sounded weird. Then I'm using really big headsets that have noise cancel so the sounds may be difficult to locate where in the case they came from.
Is it more of a popping "whoomp" like you just turned a speaker on/off, or more of a pop/click sound? If you hear the second one, and it happens repeatedly, as often as not it's just something loose inside the case that's dangling down near a fan and gets hit by it every so often, or bangs against something else. You may want to check that there are no loose ends, no pun intended.
I do have to add though that my cpu cooler (Coolermaster v6 gt) has a 4 pin cable going DOWN the case so that an LED on it powers up and it meets a power supply 4 pin connecter. It rests at the end of my graphics card's PCB. Maybe it could be that? So many possibilities that the sound can be coming from.
What sounds would give signs that it would be a more serious issue like HDD failure etc..?
I have the same case, power supply and gpu as you do and I am experiencing similar sounds. Every so often (mainly when playing games) the pc makes what can best be described as a "popping" or settling sound. It does sound like it may be coming from the case itself an not any of the componets maybe... Have you ever figured out what was making the noise? Does anybody else out there own a phantom and have similar issues? I am just betting its the weak metal in the side doors flexing with changes in temperature or fan vibrations...Anyone?
I have never seen this in a computer case, but I have seen sheet metal "pop" when temperature changes, when the sun comes out for example, its very common. I suppose could happen in a computer case as the system heats and cools.
