5 fans 7v seems to be the best. Did you have consistant workload over all the tests?

What were the extra fans you were using?

I have a define r4 with 3 noctua fans in the first config you show (front 1x NF-A14 PPC 3000 PWM + 1x NF14 PWM, rear 1x NF14 PWM)

My point exactly. I can easily lower the CPU temps more if i just touch the fan curve of the CPU without changing the noise at all... For the tests, the fan curve for the CPU is this:

All of this to be able to see some quantifiable difference in the temperatures.
