Hot glue on coil whine

[Jakubrrrr]

I have a 1660 super and tried to undervolt, the coil whine did decrease but not a lot, would putting hot glue on the coil harm the components? Is it something that is easy to do or hard? I want to know if that would solve the issue, if not then would someone send a more in depth video on how to undervolt to get rid of coil whine.

Are you sure its coming from your GPU? because out of all my graphics cards, my 1660S is the only card that doesnt whine. I am not saying every card is the same but this is a relatively low power card, it shouldnt scream like a banshee. As far hot glue goes, please dont. You will just cause more and more problems especially since you will be covering components with hot glue and reduce their cooling.

Coil whine usually comes from internal vibration, at least in components common to current computers, and is notoriously difficult to track down to a specific component. Even if you got the right component, hot glue would do nothing but get hot glue all over your GPU.

I believe the right way to do it is thermally conductive, electrically insulating epoxy.

 

Hot glue would be useless as it would simply melt when the card is under load plus it becomes conductive over time with heat exposure.

Yes it’s from the gpu, would something like changing the psu help the issue as I read it sometimes could help but I’m not sure.

This would be my issue with using hot glue aswell , You will basically be insulating the coils and stopping the heat from escaping.

That can be true that a PSU issue can be weird with power delivery and the GPU behaves weirdly: Thermally, functionally, electrically, etc.

 

750W PSU caused stutters on loading scenes in SOTC and coil whine in spite of only using 500W. Replaced PSU and no more issues.

 

No way to rule it out for sure unless PSU is at least temporarily swapped out.
