What is the best driver for ethereum? Im using 18.6.1

In terms of hashrate there is no big difference. We found that 18.5.1 are the best as far as stability goes but YMMV.

i use Adrenalin 2019 Edition 18.12.2 and rx580 8gb but in this new 4.X ver i can't use -tt and -tmax and everything about fan control is not working
in ver 3.5 i set this and worked perfectly
-tt 47
-tmax 52
-fanmin 10
-fanmax 55

but now i use the same commend but when gpu go to 59 degree fan start on 24% and after it's cooling they be shutdown and again this Repeat 59start .........

This is most probably driver related. Downgrade to 18.5.1 or similar drivers. There are hardware control bugs in the latest AMD drivers. We will try to think of some workaround but the for now the best solution is to stay away from the latest drivers.

Noticed the same thing with the latest version and some RX580 under Linux.

Had -tt set to 68 and one GPU kept creeping up way past 80 degrees and the fan was idling at 23%.

-tt is not sported under Linux yet.

Sadly 4.1c does not support 19.1.1, as it gives the Unknown OpenCL version error and suffers a hashrate loss because of it.
-clkernel 3 mode does not even work with it. ( clSetKernelArg (-49) )

I have 19.1.1 installed and latest version of miner works normal. RX 580 8 Gb Windows 10.

Code:

That`s strange... Well, I guess I can go back to 18.12.3 until we get a fix.

In your log we can see that you have two versions of the drivers mixed up. The 19.1.1 are recognized properly but there are others too (probably "leftovers" from the previous driver version). You should use DDU to completely remove the drivers and then install 18.5.1 or other drivers besides 18.12.x and 19.1.x, which seems to cause problems.

I see totally minuscule reported hasharete improvement with "3" kernels, wonder if there would be any real hashrate improvement.

The real hashrate improvement will be the same in the long run. However make sure to check your power consumption as it may increase in some cases, negating the benefit of the slightly higher hashrate.
