Also about flow rate, dunno why but I had better water temps when I had a slower flow than I have now.

The first time I reassembled my loop i switched by mistake the waterblock inlets and outlets and I also mount the internal blade wrongly, this gave me a really bad flow, I just tell you I spent 1 week waiting for air gaps to fill before discovering the mistake.
During this time even if the temperature of the cpu was worse, the water and the gpu temps were better....really I think I would go mad and bang my head to the wall till I start understanding something T_T

That's what I thought bud, I think at this point the only option is to make few experiments...unfortunally without a sponsor to give you nice things, try the experiments would be to expensive to do.
I will try ask few youtubers and hope some of them would make some proper confrontations...fingers crossed.

I would say: massive reservoir like a spilling bathtub.
Your CPU got hotter (wrong mount, it kept the heat) -> less heat was transferred to the water -> better water temps.

I was basically saying you need gallons of cooling fluid for flow rate to even come into play.

As for why you may have had better temps with a lower flow rate. More restrictive(read the components created turblent liquid flow through them, making more liquid come in contact with the conduction surfaces, the fins of the radiators or the flow channels of the blocks).

Watercooling is a very complex subject with a mix of speciality fields of study, mainly thermodynamics, fluid dynamics(mechanics) and material sciences. I doubt a single person alive has a mastery of all the fields involved and the desire to use them to just cool their computer a few percent more efficiently.

thanks a lot finally I understand one of my "problems", I thought it was for that reason but I needed someone else to tell me that for having some sort of proof smile.gif.

Thanks I feel less stupid now XD, btw I think at this point I will follow some university courses, here in italy if you don't do the final exams you can follow lessons for free tongue.gif I hate to do something without knowing why is better doing one thing instead of another.

Ok guys in case someone else need this info the EKWB support answered

«A monoblock will have a bit better flow rates and thermal dissipation compared to a CPU water block + MOSFET water block. But this will be in a range <0,5°C».

I think this solve the problem smile.gif

Exactly as i told you smile.gif Im using tge x99 monoblock and extremely happy with results.

Eehehehe, I did trust you and I thought so but still I felt the need of an answer from an official source that worked with both solutions, since there were a couple of users that did not agree with it.

That's a massive reservoir.

And to OP go two separate blocks. Monoblock is like a GPU block. Has no value in a future build. VRM block may not work on your next motherboard, but the CPU block will work just fine. Temps won't vary enough to make a difference. Honestly, the difference would be the short term cost being a bit more since you will need 2 more fittings, long term it will save you about 50 bucks, so just go with whatever you think looks the best.
