Suggestions for better cooling performance? (Ryzen 9 3900x overclocked 4.3-4 GHZ)

[eeeee1]

I hate not getting my money's worth when I buy stuff and since this was my first build, mistakes were made. (Ryzen 9 and a 2060??? What was I thinking?)

So I have a Corsair H100i Platinum RGB. When I was first putting this rig together, I went to BestBuy to see what they had. It happened that they had this one and after a quick google search, seemed like a ok cooler.

So now back to present day, after fixing some mistakes I made during initial set up, (accidentally plugging the aio fans onto the case fan headers, pump connector on pump header (I find it odd but ok))

When browsing the internet using Chrome, (usually 6-12 tabs open and maybe a LTT video on 4k or Spotify open playing music) my temps are around 42-5x degrees Celsius.  If I do something like open a new website or another application, 

my temps can spike by 4-10 degrees Celsius. What is really odd is that during idle, I sometimes keep my browser and Spotify open, my temps can vary drastically. (like my PC hit 70 degrees today. no games or cinebench or whatever)

 

Should this be expected sorta or is did I really dun goof my first build that much. And if so for both, is there anything else I can do to improve my temps even by a single digit? (adjusting overclock or fan curves, etc) 

 

Feel free to ask for more info (fan curves, whatever)

 

Here are the rest of some relevant (I hope) specs:

AMD Ryzen 9 3900x (a picture of my overclock):

MSI MPG X570 Gaming Edge Wifi

G.Skill Trident Z RGB 32 GB cl14 3200Mhz

Zotac RTX 2060 (a picture of my overclock):

Corsair H100i RGB Platinum

NZXT H510 (a rough picture of my airflow): (still using stock fans)

Try removing your cooler and see if there's some parts that don't have thermal paste on them.

It could be mounting pressure too - the weird spikes could be only some cores getting the full cover and the others not.

My guess.

best thing i can come up with is that the voltage for your cpu is too high

I can't lower them any more or else cinebench (my stress tester) crashes. (idk if cinebench is a very good stress tester but would like to hear)

well how about this, compare your oc vs with your cpu on auto with pbo enabled (you may have to restart your pc to turn on auto and pbo)

when its on auto the voltage adjusts itself in realtime to prevent said shutdowns, and doing this will help tell you if the added heat to the cpu is worth the performance gain you may or may not get.

Pump speed, mounting pressure, and Tim spread are going to be your first checks 

 

Spike like this do happen on ryzen CPUs.

 

Your aio cold plate is designed to be primarily used with single center die cpu mostly intel. Which usually slightly convex to ensure solid pressure in the center. You'll want to make sure the screws are tightened all the way. 

Or you can lap the CPU and the cold plate to make both of them flat. 

 

And maybe I missed it but case do you have?

I have a NZXT H510 (yes yes i know it kinda sucks but at the time i thought it was pretty neat). sorry for the "Mark as Solution".+
