Does burning-in a GPU by stressing it with coil-whine producing load reduce coil-whine?

It seems the entire R9 Fiji line, to which my GPU belongs, has this horrible coil-whine problem. My RMA is worse than my original purchase.

In regards to user-action that can be taken to reduce coil-whine, Amdmatt, from AMD Communities, states:

Find a game or application that produces the most whine and leave it running for 12-24 hours. This may soften the whine over time.

Is this true, and if so what is the reasoning behind how this reduces coil whine?

Update: It's not true for me that burning in as described above will help in any way whatsoever.

In general, coil whine can be caused by a cheap power supply unit - low grade components - or the graphics card itself or both.

Since, as you've already mentioned, this is a known issue for the production line of your graphics card you could do the following:

( - check, just in case, if your psu makes the gpu produce the coil whine)

• get used to it

• do the burn-in or play games with heavy gpu usage

• rma it

Regarding the burn-in, from my personal experience, there won't be much of a difference. My old gtx580, after years of heavy gaming, still produces coil whine.

If you choose the rma option, you are up against the lottery (as you've seen). You could get a new one with the same, less, or even more amount of coil whine...
