Thanks for the advice. Ran BF1 again and highest core is 72c rest in the 60's so not too bad. Will have a think about it. Be nice to get my 4770K to 4.6ghz.
Cpu runs hotter than gpu and I generally tend to put cpu before gpu in a loop to maximise cpu cooling. 70deg for 1.2vcore is pretty high imo.
You've also got pump/res after rad and before gpu. Pumps create heat so your layout isn't as efficient as it could be.
Think about changing it to pump/res-rad-cpu-gpu-pump/res.
Adding more rad surface area will help but as you don't have any temp issues with current setup I'd say you'd be wasting your money.
If you're looking to oc further though and add more volts then it would be beneficial.
