Hi,

I have some questions to make
First of all my rig Is the following:

5900x
Asus ws x570
32gb 3600Mhz 16
2080ti
850w evga G3
2tb SSD nvme 4.0
Noctua NDH15

I have installed recently the 5900x and when I First installed It the GPU led on the mobo was on and It Will not post, After I unplugged the computer and restarted It all went fine. Why this happened?

So next step I Ve done some prime 95 to check temp and stability, runned for two hours all was fine, CPU max temp was 80C, but I noticed that the clock was only 4GHz or 3.5GHz on all cores, why that? Shouldn't be 4.6GHz ish?

I enabled PBO, but didn't check the clocks on the cores, but the temp fine as fare as 95C was this normal?

I like this case a lot, but I Need Ill rebuild the PC in another case, a pain in the butt to re do the cable management but eh.

What are good cases out there ? 100/160€ budget?

Wait!, first of all, now that we have an idle temp, and no side panel temp, is a good time to tell you that 80°C its not a horrible temp for a Ryzen 9 5900X under air cooling. Of course is not a good idea to run at 80° C 8 hours a day, every day.
But every now and then 80°C spikes or even a few horus of working shouldn't hurt a lot. And according to AMD, its a normal behavior for Rzyen.

Also before changing the case, Are we sure the front fans are working as intake, and the back and top fans are working as exhaust ?

Well ima be off for now, its getting late!

I'm still rocking a modified HAF 912.
Hidden inside my desk.
Cases are purely based on style preference. Same as women.
What I like and think is sexy may not be your cup of tea.
Have a look around. find a few you like the looks of.
Check a few reviews or post links here for them and we can have an Idea of what you like and make suggestions from there.

Good fans are not cheap, but they do make a huge difference in temps and noise.
Replaced my desk intake fans a few months back with some Corsair ML 140s.
Big difference.
So if you really like you case 4 good fans could make it possible. But they cost as much as a mid range case which will most likely need a few extra fans added as well.
Conundrums !!!!!

On mine the first 10 -15 tests or so the temps are low. then the tests change and temps get higher.
Test change again and temps get lower.
Not sure but mine behaves like that. Some tests run the CPU hotter than others.
Of course my testing is considered "EXTREME" by most standards.

An idle temp (meaning the CPU isn't do anything, no games, no testing) of 68C is too hot. It indicates as issue (heatsink, crazy overclock, horrible airflow). Idle should be much lower.

What i meant is my idle is much lower. No sure of exact temp is , my computers never Idle.
The first 10-15 iterations of prime 95 push my cpu to 72c or so.
the next series of test push it to 82c. Later on it can drop back down and go back up.
My stress tests are measured in days. it takes about a week to push everything hard enough for me to feel confident with it.
Then it folds for the rest of its useful life.
More demanding than many "Stress Tests".

Sorry, but I am trying to determine the OP's idle speed. Not yours.

I have 80€ of noctua fans inside xD
Also of It spikes at 80C for 2 seconda no cooler, nor a custom loop can dissipate that amount of Energy that fast, I think its Just ryzen.
But After I game a Little bit It Just set at 65 during gaming on rust

This good. It was hard to follow with all of the input throughout the thread. I really don't see a lot to be concerned with regarding your system temperatures. They seem acceptable.

Yea, freaking out for strange behaviours.

Now with side panel off Is 68/70C with prime95
While gaming 65ish

The only things are that temp spikes that cant be removed, but its Just ryzen

The second slot is 16x physical but 8x electrical.
So in theory it could limit the card but testing shows no performance difference with todays cards when gaming.

I cant put It in the First pcie slot, maybe when Ill buy a new case Ill mount It with a riser.

Also, standing at the same chart I am running also 2ssd nvme, One 4.0 and the other 3.0

The First One have no problem, full in spec
The second One (3.0) goes half the Speed, should be only by the fact that Is plugged in a 2x nvme slot?

Yes your 2nd M.2 only has 2 pcie lanes instead of the normal 4 lanes..
If you need more or faster drives you can plug a m.2 pcie adapter into the second PCIE slot when you move the video card up to the first slot.

Ok, so my main problem now Is the case
I was checking the CM h500p mesh and seems a very good case with good airflow, also the meshify 2 seems a very good case, wich One would you pick?
Also main problem Is that the only way I could mount the GPU in the First slot Is using a riser cable to mount the card vertically, so I would like some clearance between the panel and the card, or if thereis a method to mount the card horizontally using a riser cable to the first slot
