Odd fan noise

Hey guys, I just got a Sapphire R9 290 Tri-x, Asus Z97-A and an i7-4790k and upgraded my rig. I did a fresh windows install and also bought a bigger PSU, it's a Corsair CX750M. I know the PSU isn't the greatest in the world but I got a good deal on it and from what I've read it's a pretty good PSU. My BIOS and drivers are up to date, and I haven't OC'd anything yet, as I'm still waiting on a Noctua NH-D14 I ordered from NCIXUS about 2 weeks ago (ETA another week, should've ordered from superbiiz). So right now I'm stuck with the stock fan.

Here's my problem, every 25 minutes or so I hear a noise that I'm 90% sure is coming from the CPU fan that sounds almost like it's turned off for a split second, or like a fan blade barely touched a wire. I took the side panel off and waited and actually caught it when it made the noise, visually nothing changed, it didn't look like the fan speed changed at all and it for sure didn't turn off.

The only lead I have right now is that AI suite seems to be a little wonky, it freezes my system if I run CoreTemp while AI suite is running, and AI suite itself crashes if it's running at the same time as Open Hardware Monitor. Once when I heard the noise AI suite crashed, it just stopped running right when the noise happened but only that one time. Even with AI suite closed the noise still occurs (although I'm not sure that just closing the program ends the fan control?). Could AI suite be causing this issue? All my temps are fine, and the system is stable otherwise. Obviously I'll know more once I get the Noctua cooler, if it makes the same noise then it's not the fan. Any advice would be appreciated guys, this noise is making me nervous.

Thanks,
TheFinder
 
As much as I like AI Suite, it can definitely have issues. What has worked for a lot of people (and me) when the program acted unstable, is to just uninstall it using the AI Suite Remover, and then reinstall. May not have anything to do with the fan, but it's worth eliminating as a possibility (and for its own sake).

Before you reinstall it though, run the computer without AI Suite and see if it makes the same noise.
