I would suggest the OP is listening with a stethoscope and does not have what 99% of the percent of the population would call coil whine....or you know.......has tinitus.![]()
You've either got terrible luck, or something else is causing that whine....
I'll add to my list to offset yours...![]()
Club3d Radeon 9800 XT - No
Powercolour Radeon x850 XTPE - No
MSI Radeon HD3870 - No
Sapphire Radeon HD6950 - Yes
The sapphire HD6950 toxic did have quite severe coil whine. I solved that problem using clear nail varnish over the coils, now pretty much silent with slight noise on the credits screen at the end of unigine benchmarks. I also had a ground loop from the sound card to my amp which picked up bucket loads of noise from the gpu, like scrolling etc which caused chirping noises through my hifi. Isolation transformers cured that issue.
Other parts that make noise.
