Squeeking sound coming from desktop

[howdoyouturnthison]

It sounds like a messed up fan or something but I've tested all of the fans (except the PSU) and the squeek still persists. All of my components are pretty new (I've owned them for about 4 months) so it's strange to me that this is happening. I haven't been able to spot any patterns in the squeeking sound. The loudness is random, the times when it starts and stops are random, it started happening randomly. Anybody have any ideas? I appreciate any help as it is getting on my nerves and giving me a headache. Thanks.

Here's the obnoxious sound in its full glory.

Is it possible for you to test the fans on a another system one at a time, and if you see problems just replace the fan.

I've tested the fans already (other than the PSU) by stopping them with my finger, and seeing if the sound kept happening. The sound happened regardless, which let me eliminate the case fans, heatsink fan, and gpu fan as the problems.
