Power Supply or GPU Problem?

[Hitman84]

I just started to notice a sound coming from my system after installing a 3TB HDD and a 512gb SSD. At first I thought it was HDD activity and the drive was bad. The sound happens I'm noticing whenever more power is needed, especially in games.
As far as I can tell the sound is NOT coming from my HDD tray or SSD and is in the general direction of my Video Card and Power Supply. Every time fans kick up a little bit the sound happens, I THINK the graphics card fans..
After a reboot it seems to be happening less

Here's a video I took quickly of the sound, most of what you hear is fan noise but you hear it pop in for a second or two.

I'm honestly not sure WHAT the problem is but I'm leaning towards the PSU or Video card

My system componenents consist of

ASUS Maximus VI Formula
Intel 4770k
Asus Direct Cu2 780
2 SSDs
3 HDDs
NZXT Kraken X60
4 Fans
Internal EXtra USB Hub
2 Optical Drives
Seasonic G Series 750 Modular PSU

As for the ticking noise, fan is hitting a shroud somewhere .... put finger on center of spinning fan (not on blades) and stop it.... if noise stops ya found it..... can also use a paper towel tube to listen to confined areas.

BTW, have same MoBo, CPU, GFX card (x 2), 2 SSDs, 2 SSHDs .... custom water cooled tho.

Often the fans that come with computer components are made with plastic bearings - and as dust gets into the fans, it breaks down the bearings, creating loud noises - especially noticeable at high RPM. If you stop the gpu fan with a finger - you will be able to determine if it is the GPU fan - you may have to go through all the fans to determine which one.

When you find which one, you can replace the fan or replace the component.

thanks guys. it didn't occur to me it could be a fan. was able to mess with the two fans in my system controlled by fanexpert and singled it out. when I cranked the speed you could hear the sound for a split second. seems like a very small rpm variable was causing it and as the fan dipped in and out of that section it happenned.
