My card has some coil whine, but only when I'm pushing it really hard; It can be hard/impossible to hear with an air cooler. I started fiddling around again to find suitable clocks for gaming and decided on +100mV offset and I'm stable at 1200/1500 with no apparent coil whine.

Interesting. Thin Copper with TIM may be more effective than a pad. (unless electrical conductivity is an issue? Pads are dielectric.) I guess you'd anneal (soften by heating) the copper first .... if trying it.
No round up that I'm aware of, but waiting to hear from Gunderman456 about what kind of a difference the Fujipoly Extreme 11 W/mk make compared to EK stock. I observed 23% lower temps switching from XSPC stock to Fujipoly Ultra Extreme.

Another question, planning on doing a water cooled build, Should I get a EK R9 290x Acetal + copper or nickel? Planning on using distilled water with PT nuke. I heard about changing the thermal pad when applying the water block, What kind of thermal pads should I get and what thickness is needed? What is a good thermal paste I should use, Right now I have AC5 and swiftech tim mate...?
I have used EK Acetal Nickel blocks for HD4890, HD7870, and GTX 670 with no issues at all. The benefit of the nickel is obviously the bling factor and it cleans very easily. Bare copper will end up getting stained from TIM like a CPU heatsink.See my link above; Fujipoly Ultra Extreme make BIG difference for me.
EK use 2 different thickness pads, 0.5mm for RAM and 1mm for VRMs. RAM doesn't get very hot so save your $ and use the supplied EK pads for that. I upgraded the thermal pads for RAM to the Fujipoly Extreme and observed no gains from the additional money I spent.
Just buy the $20 Fujipoly Ultra Extreme 15mmx100mm piece and upgrade just the VRM pads.
EK recommends EK TIM Ectotherm, Arctic Cooling MX-2 ™, MX-4 ™ or GELID GC-Extreme. I've had very good luck with Xigmatek PTI-G4512. Others like Noctua NT-H1.

Benchmark/Stress test are going to load everything more heavily than a game and cause higher temps. If you have no issues while gaming I wouldn't be very concerned, especially if your VRMs are maxing at 80C, you should be just fine.
