Coil Whine - After adding water block?

Hi, I have an EVGA 1080GTX which has ran fine for a short period that I tried it out gaming with the standard FE fan on. However, when I installed my waterblock as soon as I open a game full screen it gets seriously loud coil whine. Has anyone got any idea why this may be? Was the fan masking this noise? Have I broke it? Have I not put it together correctly? Is my PSU not good enough?

I did install my new CPU at the same time and overclock it, I had the CPU in my signature originally.

I have:
Skylake 6700k @ 4.5ghz
1080GTX FE
3xSSD
D5 pump
2x16gb ram
5xfans
RM750i

Cheers
 
I'll try with vsync on thanks. Some maps I get around the same FPS as I was previously, but it happens even at the menu screen where FPS is always just capped even before hand.

Before I bought the PSU I looked and 750 was more than enough from what I could see for my requirements so hoping it is not that.
 
I put the pads on the backplate so I believe so, but I will confirm it coveres everything.

How do I know what pressure to put on the screws? Is it just loosen off, test, loosen off test?
 
I would be very surprised if the stock cooler hidden this noise. The stock cooler wasn't all that loud, but this coil whine is seriously loud. If I was a DB meter, I would rate it at about 60db.. It is VERY loud.

Surely my PSU should be able to cope with the spec I have and it can't be that?
 
Been busy and not had a chance to test anything, I have a spare PSU that I upgraded from, still not a bad PSU... Wondering could I plug that PSU into my graphics card and then bridge it as if I was going to test a watercooling loop and turn it on at the same time as I turn on my PC so that it has it's own power supply?
 
Ok so a little update, after sorting some personal things out I have been able to sit down and have a play with this...

I've tried vsync on and off, no difference.
I tried bridging my old PSU to power the GPU only - Same thing, it's a decent enough 700W so I don't think it is PSU OR lack of power.
If I lower the refresh rate to 23.9 or whatever it is in BF1, it's almost if not silent.. As I creep up to 144 it gets louder. Depending on the screen and what's happening the sound changes, when going through menu's etc.
Loosened the screws on backplate no change.

I've tried on other games, like CS:S etc and it whines there too.

I don't want to empty the loop out ideally, but if I have to I will.. Is there anything else I can try?
