I think your RB temps are normal, if your using RB ver. 2.56 it uses AVX which will create more heat as it uses more current
AVX is an instruction set for some specific work loads, it does increase current and heat, not an issue for most users, just set an AVX offset of 2 or 3 just in case
As load increases and draws more current you will encounter vdroop, some vdroop is good, adjusting LLC level allows some control of this so you don't have to run vcore as high as you would without using LLC
Your pump speed and fan speeds are good as long as you are comfortable with noise levels, I don;t use headphones so I prefer a low speed, low noise fan but this is always user preference
My ambient's are similar to yours and cooling is very similar, I have my pump connected to the AIO header at full speed, rad fans connected to CPU header controlled by CPU temp
your idle temp won't drop by much unless you run the fans at high speed after delid but your load temps should improve dramatically allowing either high clocks, lower fan speeds or a combination of the two
I use adaptive vcore and balanced power plan myself for 24/7 usage, there a numerous threads about adaptive vcore in these forums
