Check and see if the pump is actually running on that AIO. If it is old it could have a bunch of air in the line which can also make the pump just not do anything.
I am 99.9% sure that if the pump was not running at all the CPU temp will rocket at 100+C in a few seconds.
I've tested this involuntarily when I first connected wrong my LF-II 420. Took about 20-30sec to go to 102C in BIOS.
Also the LF-III series is about 1 year old so its not old.
It could be running low speed though.
I got this 5950x today for a good price but the temps are pretty high. I don't know about the voltage. Any help will be helpful..

Something is not right.
Running at 112W 90C is not normal with this AIO even at 30C room. Actually the ~112W PPT is ~105W in reality as the PowerReportingDeviation sensor reports 106% (112 divided by 1.06 = 105.6)
The LF-III 360 is a very capable AIO and temperature shouldn't be near 80C under 150W PPT.
Done some testing about 20min ago with my 5900X with 200W PPT limit and 165A EDC limit.
This is LF-II 420 which is about the same with LF-III 360
Room temp is 22.5~23C, no case involved
I've highlighted some sensors
OCCT
197W, 1.2V, 4.55GHz constrained by the 165A limit (78C avg)
CPU-Z (stress test)
178W, 1.32V, 4.7GHz constrained again by the 165A limit (71C avg)
---------------------------------------------
Have you checked at what speed the AIO is running and also how did you connect it to the board?
Didi you use the all in one cable or the individual option?
At 100% PWM fans should run at 1750~1800rpm and pump at ~2800rpm
Personally I use the all in one connection plugged to CPU_OPT fan header as its the only option for LF-II series.
