I am moving from pcpartpicker, this is way better ! especially for finding parts.
So new user and new build.

Ok, after some fans curve tweaking i can give you a rough result.. there's still room for improving and if anyone is interested "like me" in what combination of hardware is capable of .. here it is (only cpu part for now) :

Base data
Ambient temperature, 20.5 C°
CPU clock, 5.2 Ghz (Fun fact the cpu is daily stable even at 5.4 with 1.41 V and cooling is not a problem.. but fans noise yes some..)
CPU Vcore, 1,31V
Ring 4800 Mhz
DDR4, 4266 Mhz, 17-17-36 at 1.47 volt

Test
1 hour OCCT test

Results
Coolant average temp 28° C
Cpu average temp 68° C
Vrm average temp 65° C
Pch average temp 36° C
Motherboard average temp 32° C
Pump average rpm 2700 (5000 max)
Front intake fans average 900 rpm
Radiators fans average 1200 rpm

I made another airflow curve for the build, this runs totally silence and i can just hear the pump.
Coolant average temp 30° C
Cpu average temp 71° C
Vrm average temp 68° C
Pch average temp 38° C
Motherboard average temp 35° C
Pump average rpm 3000 (5000 max)
Front intake fans average 700 rpm
Radiators fans average 900 rpm


It would have been easy to lower the CPU average temp. by may be 4/5 C° using the pump near or at max speed, i just wanted to test for now air flow capabilities.

Changes already planned, just need time to mount it, n° 1 Noctua Chromax 92 mm in the back to help out a little that area wich is not very well covered since the two front fans are quite some obstructed by the reservoir.. i am pretty sure it'll help quite some vrm's and the top radiator.
Also i will probably add an Aqua computer "Otto" fan controller for a better and finer control on the fans.
For anyone thinking i am exagerated.. yes it's true i am ! but a big fan of cooling etc.... so always looking for the top result.

"I will work on the gpu side in the next days, roughly i can tell you that locked at 2100 Mhz and with +1350 mhz on the memory i never exceded 37-38° C (gaming) and 42° C Furmark."

GPU result with above silence curve :
2100 mhz locked and + 1350 mhz memory
3 hours Star citizen gameplay
