Aquasuite has nothing to do with getting speed out off a CPU, the Aquasuite controls Aqua-Computer-Devices only.
If you want help, you have to tell use what Devices you have and what your goals are.
how i get maximum speed with use of aquasuite 2016-5.3?
to get more less temps for i7 4790K @4.9GHZ
Get a better cooler or lower the clocks as those clocks shouldn't be used 24/7 since you're most likely degrading your chips longevity. I would only clock that high for benchmarks and bring it down to a normal 4.4-4.5-4.6, which ever gives you the best temps and lower voltage overall.
What Aquacomputer devices are you using Aquasuite with?
Start here this should answer a lot of your questions I did not make this and its for the Aquaero 5. Most if not all of this still applies to newer aquacompurter components.
