okay so i should upgrade my motherboard? i dont plan on overclocking for now will i be fine for a little while with this motherboard if i dont overclock?
Yes, it is desirable to do this. This motherboard does not imply overclocking, so your processor frequency should not exceed the default value of 3600 MHz. Check in the CPU-Z utility
 
sorry if this is a stupid question im afraid my knowledge on this stuff is very limited but what is a vrm zone? my motherboard:

and i have three pretty good corsair fans in the front of this case i have:

i have pretty good airflow through my case so i do think ill be okay
Your motherboard does indeed allow a i9-9900K processor to run on it.
The question is how well.
When all cores are fully loaded the power draw of the processor can be considerable.
That power is managed by the Voltage Regulator Modules(VRM) on the motheboard.
If you look at the motherboard, you will see an area with 4 square components on the side, and two at the top. This is where the voltage regulation takes place.
Under load, it will get very hot; particularly with a 9900K.
Note also the 8 pin EPS power connector.
Compare that to the
MSI mag z390 mortar:

You will see more parts in the VRM zone as well as a substantial heat sink needed to cool them.
Your motherboard is MATX size. Nothing wrong with that, except limited choices.
Your case can hold a full ATX size motherboard.

As above, a good air cooler will direct cooling air through the cpu cooler and over the VRM area.
It will also direct airflow past a graphics card.
If you use an aio cooler with the radiator mounted at the top of the case, the airflow from the front will be diverted to the top leaving the motherboard and graphics card to be cooled less.

liquid cooling is really air cooling. The difference is where the radiator is located.
A noctua NH-D15s has two cooling towers with approximately the same radiator space as a 240 aio cooler.
The cpu cooling capability is comparable.
AIO coolers have other issues. One is that they do not last forever.
In time, air will enter the system making them unusable. Think 5 years.
And, while unusual, a liquid cooler will on occasion leak with disastrous consequences.

Here are some images.

Not for me if I can avoid it.

The original question was how to manage heat.
My suggestion is to keep your motherboard which is now working.
Return the H100 in favor of a noctua NH-D15s.
Your 9900K will do as well as it can with the parts you have.
And, that is considerable.

B365 chipset motherboard isn't ideal with a i9-9900K. In addition to the VRM issue, as Alex has stated, it doesn't support RAM speed over 2666 MHz. If the VRM can't deliver the power it needs or it gets too hot, you will not be able to reach the boost speeds of the i9-9900K.
 
It's easier to say that the Intel Core I9 9900k processor and the motherboard on the H and B chipset are not a balanced assembly.
True enough if one was buying new.
But, the OP needs to deal with what he has.
There will always be some sort of a limiting factor in a pc.
Usually either cpu or gpu.
If what he has does the job now, there is no need to change.
And, on the heat issue, the cpu will monitor it's own temperature.
If it detects a dangerous temperature, it will slow down or shut off to protect from damage.
That is around 100c.

Yes, but we deviated from the topic of the question. The guy asked which cooler to choose instead of Be quite! Pure Rock 2. My answer is Be quite! Dark Rock 4. TDP 200W. In fact it will take away the heat about 170W. At this moment

i think i understand now. upgrade the motherboard in the future but for now its okay. i have the h100i coming in the mail is it worth trying to see if it cools the cpu and vrm well? or should i just cancel and get this instead completely? https://www.newegg.com/noctua-nh-d15s-chromax-black/p/13C-0005-001M2

because i do have good airflow im pretty sure, and my 3070 has never gotten past 60 C before but maybe thatll change with the aio i dont know.

I would cancel and use the noctua.
But, that is just me for the reasons i posted.

You do what you wish.
okay ill do that then its cheaper and you said itll work well with what i have. you said that the noctua i linked will fit in my case?
