I'm using the Noctua TIM, NH-D15 inside of a Corsair Air 740. I have the two stock intakes, two bottom intakes I added, stock rear exhaust. The two fans on the NH-D15 are intake and middle - I figured with the stock exhaust this would be the most optimal fan configuration. There is also a low power GPU installed currently, GT 610. Eventually I will put my RX 480 8GB in.
I tried that as well to run more VCCIN but didn't helped me with lower vCore or lower voltages
You can try to increase Ring or Cache voltage which can help with bringing the CPU vCore down, in some cases on my older RMA 5960x this helped me bring vCore bit down, but I would personally don't go beyond 1.15-1.20v on cache voltage
If lifespan is yours concern then I would stay under 1.35v on vCore but there are lots of conflicting information on max voltages too which didn't helping a lot here
Noctua TIM NT-H1 is pretty good and using that TIM only on GPUs and on CPU I use Kryonaut which is working fine for me
NH-D15 is my favourite cooler and I would keep it, if fans are yours concern or colour of them, please have look on Thermalright TY-143 or TY-147A which I used them on my NH-D15 and personally I loved both of them there
Hope this helps
