Hi there,
I've had my pc apart about 5 times over the weekend trying to seat my H100i cooler. Finally got a good seating and low temps.
Annoyingly, now, only when in games I get a buzz from the speakers. It's fps related - if I look at the ground/sky the buzz gets higher pitched as fps increases, similarly, if I go to a lower fps area, the buzz slows down.
Switching to my usb wireless headset, there is no buzz.
I assume there is an interference issue between the GPU and motherboard on-board audio. I'm using the rear I/O connector direct to the on-board audio realtek module. connected to a set of creative speakers with an expensive audio cable with shielding.
Points to note: I put some washers on the H100i backplate which meant it touched the base of the motherboard tray - put a piece of A4 in between to see if electrically isolating made any difference - nope.
Thought maybe the GPU was actually coming into contact with the audio I/O block so put a thermal pad between the two - nope.
The motherboard mounting screws have worn 'some' of the little solder dots of the top face of the motherboard (I assume it needs to earth?!) though I assume the motherboard itself earths primarily through the ground of the 24 pin power connector?
I assume it doesn't matter if the I/O backplate touches the rear connectors, in fact, I assume this is the design.
Can't think what else to try, other than try it without the GPU (RTX 2080) installed, but I pretty much know the issue is interference between the GPU and board.
Any locations on the board I can ground with a flying lead to give the best chance of grounding?
