Question My 9800x3d 89c on multicore 2024 cinebench.....is this normal?

I have added 200mhz to the boost clock (5.4ghz) + i have the fan curve on arctic liquid II running in the arctic recommendation for the silent mode and i have an undervolt of -25. 89c seems a little high to me with a high end liquid cooler and a -25 undervolt + a high end mx6 paste.......is this normal? I have it on silent mode as i said but it should not matter as the fans are set to go to 100 percent at 85c

Just because you have liquid cooling hardware, doesn't guarantee you have it optimized. Is the pump at 100% all the time? Do your fan curves max out your radiator fans? Do you have sufficient intake air (or exhaust capacity)?
Have you tested with the side panel removed to ensure you have no airflow restrictions ?

Everything correct here right? The only thing im not sure of is if the case fans up top go up or down, currently have them pointing up as you can see. H500M case by the way

I can't tell fan direction from a picture, but I assume your fans on the radiator pull in cool air. Do you have single fans or push-pull ?
Again, have you tested with the side panel off ?
 
You will never be able to compare some absolute temp number with other people way to many variables. The largest being the room temperature you start with but case layout and fan selection also makes a large difference.

Does it really matter I guess is a better question. At 89c you are still below the thermal throttle limit of 95c. This means you should be getting maximum clock speeds with no dropping because of thermal limits.

Nothing is going to ever load the machine like cinebench does so for normal usage the temps will be far lower.

My 9800x3d does behave a little odd. I come from 11900k rocket lake, was using that for years, maybe all of this is normal for Ryzen? High clocks in google too, seems to always be at the max boost clock i have for it (5.4ghz). Stays at 5.3 / 5.4ghz when on google. I have 25 tabs open but the 11900k never ran at max clocks and the temps never got this hot while on google. 5.3ghz at 20 percent cpu usage

Is that how it should be? This is my first build
No. Generally the flow should be front to back. Intake in the front and exhaust in the top/back.
With a radiator in the front you want cool room air being pulled through the radiator. Then you need enough exhaust to get rid of that heat so the cabinet doesn't become an oven. This is why I recommended that you test with the side panel off. This will ensure that there is enough room air even if you have the fans poorly organized.

I tested with side off and it seems the same. Here are some pics of how i have it set up
