3080 ti coil whine.

[Sgt Tackleberry]

Hi all,

Just over a week ago brought a 3080ti brand new. When it arrived I test it out and made sure it was all good before stripping it to put on a EK waterblock on, unfortunately my backplate didn’t arrived in time but I still got on with it as I didn’t mind draining my loop to put that in when it did arrive.

The card has been running really well for 6 day now with the new waterblock on. The backplate arrived yesterday so got down to draining my loop, took the GPU out got the backplate install with its thermal pads too. Filled the loop back up leaked tested and all good.

Fired up furmark to stress the card to see if the card was making good contact with the block as I had to remove screws for the backplate to be installed. Within a few seconds of this my card started to make that horrible coil whine noise! With the different sound pitches. Loaded up a few different games and depending on the load depends on the noise it makes!!.

So what I would like to know have done something wrong why I was installing my backplate?. I’ve never had this happen to me before, I’ve been custom watercooling now over 10 years and never ran into any issues as I’m always careful!.

Any information/help would be great.

Thank you

Have you overclocked it?

It could just be that better cooling means the card can boost higher and stress/work the components more and so you get more/louder whine than under air.

Whine normally goes hand in hand with higher fps also.

No I haven’t overclocked it.

I like that theory. Yeah if I reduce my fps limit down it gets quieter but I game at 4k 144hz so downing the doesn’t feel as smooth!.

Just a quick one, anyone know what this is i've circled?, as i remember knocking it when i was putting on the backplate.

That looks like an insulating sticky pad, to make sure any metal backplate doesn't touch those power connector joints and cause a short/pop/bang/fire.
Hopefully your water cooler backplate has been adequately designed/installed to remove that risk.

ah that make sense. the backplate is EK, so i'm hoping they have made a good design lol,

Been looking around on the net and it seems to be a very common problem after installing a backplate.
that the thermal pads might not be making the right contact via to much/little when screwing it back together.
