FX-9590 and Corsair H100i V2 help

[Trev6450w]

I am new to the whole water cooling scene, and I was wondering if my pc was doing the right thing. When I stress my cpu hard, my cpu (FX-9590) gets to a high of 55 degrees Celsius, but normally it sits at 20-30 when idle. I wanted to reduce noise by creating my custom fan curve because the balanced profile is extremely loud and quiet profile is only quiet for a while and it surges with the fans running hard.

I am not really sure, but my H100i V2 temps sit at ~40 degrees Celsius under stress and like ~33 at idle. I also noticed that in Corsair Link, the max is 42.5 for the h100i v2. I am pleased that my pc is quiet now and has a relatively good temperatures but I just want to reassure things are all right.

Those temps are quite good considering the CPU but I would double check the temps with AMD Overdrive. Here is also a guide by damric which explains thermal margin (AMD Overdrive).
