Weird AIO cooling

[grandmasterchaou]

I recently built a new pc with a Corsair 360 aio h150i elite capellix on a Ryzen 5950x. I’m using Ryzen master (Auto preset)  to give it a slight overclock up to 5.1GHz (usually sits at 3.6-4.8GHz). Usually at idle it sits at 40-44 degrees Celsius under load (borderlands 3 for example max settings dx12 etc…) sits around 67-70 degrees with load times in between maps or travel spiking to 75-80 degrees. On occasions my cooler will drop between 5-10 degrees during load or idle  randomly upon start up and i dont understand why? I’ll check to make sure all my overclocks are still applied and they are, however I find it strange and can’t find any explanation as to why I’ll randomly get better cooling at times especially a massive cooling drop this much. (The room where the pc is is always the same ambient temperature no fluctuations)

A quick check - is your AIO leveling off at 67-70 degree at something below it's full performance and then goes into the full airplane take off mode at those map/scene changes?

 

If so sounds to me (and I am not an expert) like the CPU is being hit with sudden decompression etc loads during scene/map change, with AIO not being responsive enough thermally. If this is the case you may try to just adjust the AIO fan curves to be more agressive, pushing the AIO to 100 percent at the normal loads.
