I get 890KHash on a 290X, Elpida, @938/1500. I read linux can improve hashrate quite a bit. Beyond that?

If you're implying that Hynix modules are faster clock for clock, that makes no sense. The whole Hynix/Elpida scare was just grandfathered in from Tahiti because the Hynix IC's on average actually clocked much better. It's been proven with Hawaii that either one can be poor or golden. My card has Elpida's and can hit stable clocks much
higher than most 290X's. The usual ceiling regardless of Hynix or Elpida has been around 1500MHz, while mine does 1700 without issue.
I've seen nobody in the mining scene who was able to achieve over 890 kh/s with an elpida 290x whereas the hynix model achieves over 1000 kh/s. Is Elpida running with the same clocks like Hynix? -> Yes :O But is it as fast as the Hynix modules with these clocks? Noo!
Fact is: 938/1500 gives you 980 on an elpida and 1025/1500 gives you 1000 kh/s and could be clocked even higher. Elpida will give you 700 kh/s with 1025/1500.
It might not be Elpidas fault, the reason for the hashspeeds could be, that the '-00' models are 'golden' as you say and the '-01' are poor. But why is AMD selling poor -01 290x as real 290x?

Ofc. the Tri-X fans blow the **** out of the GPU, but what about the produced heat? It goes wherever it wants to.
The retail cooling system supports the chassis airflow from front (where the fan is) and pushs the heat out of the back. There is no way, that a non retail cooler will survive in a TYAN setup like this:
