The power draw from that CPU cooler will have no effect. In essence you are trading out 1 fan, from your current cooler, for 2 fans. Each fan will draw like 4W of power and will not make any difference. With a 550W PSU you have the minimum wattage needed for your build to have some overhead. You will be just fine.GPU:

Are you asking what its power draw is or what it can handle for TDP?How much wattage does the Noctua NH-U12A take?
Your power supply is so bad, that you're concerned about CPU COOLER FANS?!Im not sure if i have a big enough power supply, and i wonder how big the jump of power use is from the stock amd ryzen 7 2700 cooler to the Noctua NH-U12A

Ryzen 2700: Around 140w at stock - closer to 210w if overclocked: https://www.techpowerup.com/review/amd-ryzen-7-2700/17.htmlHow much headroom do you think i exactly have?
Those numbers that techpowerup has is Whole System Power with a 1080Ti. During their gaming loop with Witcher 3 the 2700 is at 351W. This not a case where you are adding 140W + 270W + X = system power as Techpowerup already has the full draw calculated with their benchmarks.Ryzen 2700: Around 140w at stock - closer to 210w if overclocked: https://www.techpowerup.com/review/amd-ryzen-7-2700/17.html
RTX 2080 Dual EVO: Find out the max power limit of your gpu. Download and run Gpu-Z: https://www.techpowerup.com/gpuz/
Click on the Advanced tab, then the drop-down box, and on Nvidia Bios. Note the max power limit from there.
I couldn't find the bios for your exact gpu, but I'll be using the power limit from the following gpu for my example: Asus RTX 2080 Dual OC - Non Evo (270w)
25% of headroom for everything else in the system...
140 + 270 = 410. 410 +(410 x 25%) = 512.5w
210 + 270 = 480. 480 +(480 x 25%) = 600w
Between 512.5 - 600w. But those are worst case scenario numbers. You're not going to draw that much normally - those numbers are from stress tests.
No worries, I don't know how many times I have misread something. Happens to everyone.@jeremyj_83
Well, crap... I totally missed that.
Down vote my answer, would you? I really slipped up there.
