Thanks for all your replies everyone, I'm gonna throw 1 more cooler into the mix with the other ones I've mentioned and see what you think. The Arctic Freezer 50? I think it looks very smart. How would performance be compared to the Scythe one I mentioned earlier? A post above says the Scytge would bring temps way down which is exactly what im after.
While weight of Freezer 50 look impressive, three fans and all that plastic crud make quite a lots of it:
Single Arctic P12 fan itself weights 140 grams.
So with all the extra crud it's safe to assume half+ kilogram of the weight is other than actual heatsink.
And suddenly we have less heatsink weight than in best single towers.
(though obviously airflow over fins is going to be very good)
Also with that huge size DIMM clearance is going suck.
With shape of AMD's heatspreaders being toward convex would recommend flat based heatsink for best cooling per money.
Igor's lab has done accurate heatspreader shape measurements using very high end equipment:

So Intel optimized convex base heatsink has risk of "rocking" on top of CPU with only small area of good contact.
Because of manufacturing process direct touch heatpipe coolers have flat base making better fit.
Possibly because of that in one Youtube video Arctic Freezer 34 achieved nearly as good results with 5600X as quite big Scythe Fuma 2.
Though if you're willing to spend some effort and time in grinding/lapping base of the heatsink flat, best contact can also be achieved with Intel optimized coolers.
From in stock cooler Alpenfohn Brocken Eco Advanced would certainly be good for frugal 5600X.

(high temps are caused by stock cooler being sized for playing MS Word)
Brocken 3 would be then example of quite high end cooler... If your case can fit it.
