Opinion on temperatures I9 10900K with XII Extreme and Custom Loop

[theotorm]

Hi everyone. I wanted to show you the temperatures of my I9 10900K in stock with my custom hard tube CPU loop.
The components are:
I9 10900K
MAXIMUS XII Extreme
Gskill Trident Z 3600mhz (no Xmp)
EK Quantum Velocity waterblock
Thermal paste MX4
EK Quantum Kinetic D5 TBE300 Pump with 100% (7573 rpm) velocity and flux 281 L/h
EK XE480 radiator
Corsair LL120 Radiator Fans

I tried 1 hour of Cinebench R23 with the fans at 100% and this is the result:



how does it look to you? Liquid Temperature max 26 is OK?
I did the same 1 hour test with 40% fans and the hottest core was 70 degrees.
Consider that the voltages are on cars.
I await your expert opinion.
Thanks a lot.
Francis
