Thanks for reply.
I installed the radiator so that the tubes are towards front of the case so they don't go to rear fan.
Here is crappy picture of my case, the scratched window ruins the look π. I have Lighting Node Pro for ledstrips and they are usually set to react to temperature. Green when cool and then yellow and finally red when temps rise. Might need to adjust those settings now π.
Oh yeah, the cpu is i5 10600K @4,8Ghz on all cores. Max load temperature was before 92C with noctua nh-u12s chromax.black. Idle temps were something like 45C.
Now with the H100x max load temperature is 75C and idle is about 30C. I'm happy with the result βΊοΈ
