1) No.
2) No. And I spoke to one of Watercool about this. They have no intention to create one for the X299 Dark. I doubt if any of the others would either given X299 is mid life and X399 / TR provides way better value than Basin Falls. Also because the X299 Dark already has good VRM cooling whereas the others with mono blocks don't
3) No. Would not.
 
My advice is use the existing VRM air cooler, get a CPU waterblock only and be happy. You will get better CPU cooling anyway without dumping the VRM heat into that loop anyway and the VRMs can live with being a bit toasty, more so than the CPU die.
 
 

Thanks for the reply.
About the block for the Asrock, why do you think it wont fit the Evga Dark? Did you try it? Have you seen both pcbs/vrm? they are pretty much the same on pictures at least, I haven't gotten my hands on neither tough.

Thanks for the tip with Nate!
 
I contacted Nate from E22. Lets wait the answer...
 
I hate it that the big brands are so focused to the crappy asus and others stuff. We only want a VRM block for this amazing board! And for me its not only the temperature, its the fact that i have a fan on the board...

Guys avoid Monoblocks. 
They advance is only 2 fittings less and look.
 
I bought Monoblock because I found cheaper and complete with Rampage E10 but I would be seriously disappointed to pay full price for him because cost 2.5 premium CPU Blocks.
Simply he have at least 5C worse temperatures than premium CPU Block as Heatkiller IV PRO.
One of reason I'm happy to switch on another platform is to buy nice CPU Block and save 110 euro compare to Monoblock.
I know exactly what model I want, Pure Black with Koolance Inlet filter on inlet port to keep him clean.
 
I completely understand X299 is series with biggest need for VRM liquid cooling but at least EVGA X299 Dark have enough good cooling and you can use only CPU Block. I advice CPU block without POM, Acetal, Acrylic. Only metal/copper. 
Watercool.de have 4 such models. Heatkiller IV PRO Black Copper, Copper Nickel, Pure Copper, Copper Anthracite. 
These are highest quality best performing CPU waterblocks.
 
Among VRM coolers on Watercool.de site maybe you can find dimension for EVGA X299 Dark.
Yes Monoblocks look nice, mine nicest of all. But If someone choose other motherboard not X299 Dark because no Monoblock...
I can't even say how that's big mistake. CPU Block with good flow and nicely build inside with simple parts is best choice.
 

I think I have an EVGA Dark monoblock that I got from EKWB and never used, I'd have to double-check.
The reason I didn't use it is that I'd have to strip a bunch of the "dark" custom cooling parts from the mobo.

guys don't go for mono block its waste of money and DARK already having best thermal design look at buildzoid

review they are impressed by the R&D design kudos to EVGA and KINGPIN AKA Vincent Lucido
