Hello! I need some help with a new build.

The complete list of components are:
Motherboard: ASUS ROG Croshair v Hero
PSU: EVGA P2 1000W
CPU: Ryzen 1700x
GPU: MSI GTX 1080
CASE: PHANTHEKS Envolv ATX
RAM: 16 GB G.Skill (4 modules * 4GB) Flare X 3200 MHz
CPU COOLER: Cooler Master Airmaker 8

I think buy the Cooler Master Airmaker 8, and i will like overclock the ryzen 1700x to 4.1 GHz, my problem its about change fan of the heatsink, the stock fan have a nice results on some reviews, but i dont know if it's necessary to change the two stock fan with specification of 140mm,1800rpm and 0.24 to 2.2 mmH2O static pressure for nuctua's industrial fan with two 120mm, 3000rpm and static pressure of 7,63 mm H₂O.

-If i buy this cooler, can i have better results on temps if i change the stock fan or you think it's better buy another heatsink (Nuctua D15, Be Quiet Dark Rock Pro 3 or Cryorig R1 Ultimate)?

I have the H5 ultimate and can oc my i7 7700k to 4.8 and stay way below the limit on temps, but does block one ram slot but I only need two and it don't block one of the first youre supposed to use. Dual channel better from what I have read anyway

Another problem, in my country the basics temps of room normally are around 27°C to 33°C, climate is tropical, i think i can't do a great overclock, only a little around 3.8 to 4.0 GHz. You are absolutely right, the PSU jus a little big for this OC, i think that 850W are just best option. Temperature management with air heatsink, hmmm for airflow i think put front of the case 3 fan of 120mm for introduce air, Cougar cfd 120 with 109cfm and 1300rpm and snother 4 fan extracting air, 3 on top an 1 on exhaust position ever Cougar fan with same specification. But the problem its on Air Heatsink of CPU, i don't know what i can do. I do not want to risk liquid cooling for a probably leaks.

I recommend NH-D15S. I have one and it's an excellent cooler. It's slightly cheaper than Cryorig R1 since it only comes with one fan, more compact, shorter, excellent DIMM slots compatibility (up to 65mm high RAM) and comparable to R1 performance. You can buy it directly from Noctua on Newegg, they have expedited shipping at low prices.

AFAIK, Ryzen Overclocking is being limited by its own power limit rather than either voltage or temp. The top end air cooler like NH-D15S or R1 can handle even minisun like the old FX-9590 so Ryzen is not a problem. They are comparable to high end 240mm AIO.

I'm gonna be real with you: You're probably not gonna hit 4.1. Its rare, and if you do you'll need very high voltage and its gonna generate a TON of heat.

I'm cooling a 1700X, clocked to 3950 at 1.375v with the mediocre Corsair H60 w/an aftermarket 120mm fan. Under load with Prime 95, in typical Prime 95 fashion, temps are pretty high. They leveled off at 85.6c (real core temp (Tdie), not the +20 reading (Tctl) you've no doubt heard about). Under stress test in Realbench she sits under 76, so good result here.

I found that to jump just from 3.95 to 4.0 I had to jump my voltage to around 1.43 and that actually made my temps take off above 90c pretty quickly under load, so I opted for 3.95 long term. A better cooler (or a better CPU) will probably help here but its a substantial hike in temps when you start getting voltage up closer to 1.45. The ambient in my build room is also 21-22c on average.

You are absolutely right, temps on my room are around 25-29°C, hmm the right option is not to do OC, and only use turbo and xfr stock of cpu... I wanted to do OC for a stupid reason , but thinking about it is something i do not need, because the power of the processor is more than enough for programming and 3D rendering... I think to buy the bequiet dark rock pro 3 or search another heatsink, thanks for your answer.
