Hey all! I got an EVGA 980 Ti FTW. Like many other 980 Ti's, it suffers from coil whine. I've already tried RMA, use other brands, change PSU, and burn in method. One method that recently peaked my interest is dealing with the coils themselves which I believe are the blocky things. Here's mine labeled with a red square.
Yes I realize they are not exposed so the common thought of putting glue on them wouldn't work.
However I've seen PowerColor do it and read a post (near the end) saying it'll help and even claimed cooling the chokes will help with the coil whine. Heck MSI's 980 Ti Gaming 6G has a layer of thermal pad between the choke and the heatsink. Reports of MSI's 980 Ti having coil whine seems to be lower as well. Coincidence? Unfortunately I can't find much information and those I listed are probably the only documentation of muffling attempts at these block type inductor/chokes.
SO, I got some questions on these chokes before I attempt anything with them. I hope someone here with experience with them would answer my questions.
1.) How durable are these chokes?
If I'll be messing with them I want to know how much force I can apply to them before they pop off or break. Such as squeezing material between the choke blocks, I don't want to damage anything.
2.) How much cooling do these choke need?
My plan is to wrap the chokes with adhesive thermal pads (at the same time install an Accelero Xtreme 3 cooler). Essentially making a shell over each block. If I do this, will the chokes overheat? I've read they are just coils and should withstand up to 105C. But I have no idea how much heat they put out and if giving it basically no airflow could suffocate them. I suppose I could try putting some heatsinks over the adhesive thermal pads, would that do the trick and keep them from exploding? Or is that not necessary? I don't want to use glue or silicon as I don't want this to be a permanent thing. I wish to be able to remove these thermal pads in the future.
3.) Would putting material on these blocks do anything at all?
I have no idea if mine are solid or hollow chokes. Assuming they're solid, putting any material around (silicon, glue, thermal pads) should act as vibration absorbent right? Or am I missing something here?
4.) Can better cooling silence these chokes?
That nforce4max from the forum I linked said better cooling does help silence these chokes (he replied to a 6970 thread and that card does use block chokes). Does anyone have any take on this? I really don't see how better cooling would help but I'm open to anything.
