case fan only decoration?

[Phobos]

I've wanted to clock a CPU from 3900 MHz to 4200 MHz for a job. (AMD Ryzen 2600)
And regardless of whether I install 5 chassis fan or 0, the CPU temperature always rises above 95 C.
Is it not possible to clock up a CPU without water cooling?
Why is there a case fan in the game?

I just tried an AMD 1800x clock from 4000 MHz to 4200 MHz but also rises above 95 C.
I have 5 coolers with 73 CFM and the CPU cooler has 100 CFM

The fans do have an impact on beeing able to OC and on the temp of components.

So your CPU fan will indeed impact on how much you can OC.

To answer your own questioning, you should go in free build mode and simply try that.

Take a simple 1300x WITHOUT OC it.
A simple case without any fans
Install 1x a 50CFM CPU cooler, and run OCCT on infinite.
Write down temps after ~45secs (will be enough for that experiment, more advanced OC needs to run that longer)

Repeat with an 80CFM CPU cooler and once more with a 100CFM CPU cooler.

Now just in that very last experiment, add 3x Cryorig QF140 perf case fans.
Compare your temps running OCCT.

You'll see that not only the CPU fan matters, but the case fans do.

Now on that experiment, please consider the "small" temp variations...
So if you crank up way too high your OC, no matter what your "traditional" cooling system will be, it will overheat.
OC is getting to know a safe base OC you'll apply to a certain CPU, and from that, you go up in small increments (up or down, depending of more room to OC or throtteling)

Now there are much better OC'ers in that game than me, so I'll let them add more on the topic, but my understanding is that some CPU's are much more sensitive to OC (and it seems realistic to real life from what I have seen those better players comments)
I think the 1800x is one of those not so easy to OC.

So maybe experiment a bit more on some Intels (K)

Now also depending on cooling solutions, and CPU, +300MHz is already a big gap.

Also please understand that in this game, there is a "silicon" lottery, which means not all same CPU will be able to OC equally. Some will be able to get higher some lower.

Now as stupid as it sounds... You have used thermal paste right ?

I try simplify my answer as there is a lot to know, when OCing CPUs and such.

When you OC the CPU you raise it a little bit, restart and go into bios again and see how the temps are, keep doing this until, you are in the low 50's and it should not throttle, but you can put case fans in the case to lower the max temp and you might have the possibility to go a little higher, than the mid 50's in bios temp wise depending on how many case fans and how much CFM you have in total.

For OC it is good rule to use high CFM case fans and CPU Cooler.

I did not forget thernal paste =)
Thank you for your detailed explanation
is the case or mainboard important? no or?

is more important the multiplier or the base clock?

Case only matters in that some of them allow for more case fans or radiators. The more cooling you have then obviously the higher you can OC without thermal throttling.

Motherboard only matters in that some can OC and some can’t. That’s based on their chipset.

As for base clock vs multiplier, it doesn’t matter for the CPU because both affect the speed albeit in differing ways. Play around with it and you’ll see what I mean. Base clock however also affects your RAM speed. So the thing to do is to figure out how fast you can get your RAM to go first and use the base clock and the RAM OC to get that. Then use the multiplier to push the CPU faster. And of course crank the voltage up to actually power the thing at your new clock speed. Play around in free build to figure out how it all works together and you’ll be able to do it in no time. And you can fry all the components you want in free build and learn how that works too.

Also Intel CPUs generally handle overclocking much better than AMD. You won’t be able to push AMDs very much in my experience.

Just to add to this simply: Case fans do effect OC but it matters which fans you install. Just adding random case fans won't do anything. You need to add as many high CFM fans as you can. Cryorig are the highest in-game. You want your total overall (Additive) CFM to be as high as possible. Fans have a CFM rating in the store, look at them.

OK thanks. how is it with the graphics cards? are there certain brands that can be better overclocked.
is the case temperature also important there?
What do I have to look out for

well of course custom water looped video cards are going to OC better than the air cooled ones.. just run the video cards up to I think 95c and see if they crash or not.

Some do OC better than others but like Aquafawks said they all will crash around 95C. I’d strongly encourage you to mess around with it all in free build. And never be afraid of OCing graphics cards because you cannot break them. They’ll only crash the system but they’ll be fine.

Last question =)
what's more about the 3d mark score? graphics card clock or video card memory increase? or both?

The CPU in the system only accounts for 18% of the overall 3dmark score. The video card(s) account for the other 82% of the score. So it's more important to overclock the video card than anything else. But do remember to at the very least load XMP For the ram in the customer's bios.
