AIO fan speed doesn't make any temp difference

Hi all - I've got a 240mm AIO on my system and I've been playing about with fan speeds etc to see what happens.

It seems that changing the fan speed on the radiator makes very little difference to the CPU temps - is that normal/par for the course? If I turn if right down to under 500rpm then the temp will rise, but putting the speeds from 500rpm - 2000rpm seems to have very little, if no difference. The pump speed is set to 100% as per the instructions (about 3100 rpm)
Edit to add fan speed also makes no difference to idle speeds either

I'm not worried about temps - using Cinebench R23 over 10 mins with a moderate fan speed gives cpu temps of 67c. I just thought fan speed would change cpu temps - guess not?

Cooler is a Silverstone PF240 and the CPU is a Ryzen 5 3600

Cheers

Thanks for the replies. Guess I'm used to air coolers where the speed makes a big difference, coupled with a lot of spare cooling headroom!

As has been said, I've got a nicely running system that is very quiet, so happy days!
