First time PC build help!!!

Level 7
Hello, i have successfully built my first pc. I have a few questions but first here is what im running:
Rog Strix z490-e
ASUS GeForce RTX 2070 Super Overclocked 8G EVO GDDR6 Dual-Fan Edition
Intel core i7-10700k
ARCTIC Liquid Freezer II 280
Corsair CP-9020195-NA RM Series RM750 80 Plus Gold Fully Modular ATX Power Supply
Corsair Vengeance RGB Pro 16GB (2x8GB) DDR4 3600 (PC4-28800) C18 AMD Optimized Memory
FRACTAL DESIGN Meshify C TG Dark Tint Tempered Glass Window ATX Mid Tower Case

So first question is, is it too little power if im going to oc?

Second, how do i connect more fans since theres only room for 2 chasis fans on the motherboard(i want to be able to have the motherboard control them) the AIO cooler is quite bulky and i have it on the front. Its like 2-3 cm away from my gpu. I didnt want hot air blowing into my gpu so i have the air blowing out from the front. I also have the back as exhaust. My only intake at the moment is from the top. I have only 1 fan there. I want to add 2 more fans. Giving me 1 on the bottom blowing in, 2 at the top blowing in and exhaust out the front and back. Is this a big no no? Or am i okay with this airflow system?

Also the little fan that came with the motherboard doesnt spin ever. I connected it where it goes and everything but it never spins.

When overclocking, how do i know it is overclocked? Im having a really hard time seeing exactly whats what. I also dont know what my graphics card being" oc" means exactly, im not very good at this so like a step by step on how to see would be helpful. I used the 5 way optimazation and ai overclocking to do all this for me. But i just dont understand half of this.

Any advice on anything from the build even if its not exactly what i asked would be amazing please and thank you!

Hi, That's a lot of questions in a small bundle. Power should be adequate. If you want to add more fans, you'll need some kind of fan hub and check to see if each header on your board will deliver enough power for additional fans. If not you might want to add a usb 2 fan hub to a spare header on your board.

I presume that you have kept an eye on temperatures with your current fan set up? You need to observe what's happening temperature wise and configure your fans around that.

I have a small case and I have a 280mm Rad on the top with two 140mm fans blowing out the top, two 120's on the floor of the case sucking in, and two 120's on the front sucking in. I have mine configured to run the top two at 500 rpm and the other four at 650 ish, they then all ramp up to custom curves in pairs determined by my zone selection in terms of temperature in different areas of my build. This allows me to stress test, to work out the best configuration which will balance noise with the need to keep the temperatures in a good place.

How will you know when it's overclocked? Either the app you use in windows to overclock or the setting in your Bios you choose will bring that fact to your attention.

The little fan, does it show in any of your data within your monitoring? Read the manual that came with the board and see what wisdom if any it has on the subject.
Or maybe be more specific about the intended location of the fan and its purpose.

Again, overclocking your graphics card will be something that you personally action, you'll see when you have changed a parameter, and if it crashes you'll know that's not the best setting 😉
