My turn to need help.

LFFPicard

Right all,

I have an odd one here, I think I know what it is but unsure. The last few days I have heard a noise coming from the PC, now thinking it just needed a clean I pulled the desk out a bit got down and gave the PC a good blow with some air duster.
Took the side off, aired out the inside etc etc, now I noticed the noise was coming from the back end of the PC. I _THINK_ it is coming from the Rad/Fan on the Coolit ECO, I have made a recording Here you will hear right near the end a almost gargle sound.

I have checked temps and idling at the below temps so it is not effecting the machine. I did notice last night my video card drivers failed and recovered a couple of times, but only while I was browsing after a 3hour Fallout 4 session so that was a bit odd but I will strip the drivers out and install them again anyway.
Any ideas?
