Hello, I built a pc 1month ago and i had only a decent case with 6fans but with a lot of tuning and experimenting I managed
to make it work increadibly well. On CineBench R23 i would get 92C max temperature with the score of 40.50k pts and also
I'm using contact frame. Later on I decided to change the case and go for Lian Li o11 dynamic evo with 10fans 6 intake and 4
exhaust and idle cpu core temps spikes to 71C for a second, cpu package spikes to 67C and stays at 52C If i start CineBench R23 test it would thermal throttle and crash

i kept the undervolt the exact same as in my previous case -0.075 but also tried different numbers which didn't help even if i lock P1 P2 to 125w 253w it would thermal throttle which is weird because previously with the exact same cooler i had unlimited power with undervolt -0.075 and it would pull 282w and max temps would get to 92C with amazing score on cinebench meanwhile now its pulling 300-320w when it's thermal throttling at 253w.. I did repaste thermal paste to kryonout thermal grizzly multiple times, reinstalled brackets, contact frame and nothing seemed to be out of place, I did uninstall the cooler and gave it a shake it few times i thought maybe there's a airbluble trapped but also didn't help also mounted radiator on the on the side as on my previous case it used to be on front but also didn't help.

Fans are going at 100% and pump is also at 100% 2830RPM. I've tried playing Hogwarts legacy at ultra settings + ultra raytracing and cpu would stay at 62-65C but spikes would go to 85C sometimes meanwhile in my previous case it wouldn't spike at all. I do hear pump working there's no gurgling sound or anything water is flowing and you can hear it. Also I changed ram from 5600mhz 4x16 to 6400mhz 2x32 and I see people running them at 1.45v but i can't set them to 1.45v in the bios it only lets me go for 1.435 or 1.425 cant recall.

Forgot to mention that in the bios there's a setting for multicore enchancment i did set it to enable which sets power take to unlimited but even if i set it to disable enforce all limits which caps the power at 253w its thermal throttling which drives me crazy as i had it working increadibly well and now i can't make it work even with lower wattage take. The only thing that actually changed is nzxt z73 fans they're no longer original fans and I use Lian Li Uni Fan SL-INF 120 so it matches my case fans. Right now i ordered a new water cooler EK Nucleus AIO CR360 Lux D-RGB which is also 360mm but i've heard many good reviews about it and maybe maybe it will solve this increadibly annoying issue that i have as for right now i have no clue what to
 
This:

"I'm using contact frame. Later on I decided to change the case and go for Lian Li o11 dynamic evo with 10fans 6 intake and 4".

If possible, as a visual starting point, take a couple of photographs showing case and fans. Edit the photograph to indicate fan airflow directions and air flow rates.

My thought is that the fan arrangement, air flow rates, and airflow directions may actually slowing down the overall airflows necessary to keep case and components cool.

that’s how the case fans are looking. Fans are usually spinning at 1900rpm which is the maximum. The top ones are exhaust and also a single fan on top left is exhaust on the bottom and sides are intake.

I always wonder about configurations where there are more intake fans than exhaust fans.

Especially with airflows going crosswise, etc.. And that big GPU sort of in the middle of it all.

Airflow(s) possibly being restricted or otherwise impeded as a result.

Plus even with fans at max rpm that does not necessarily mean that air is being moved at max.

= = = =

My thought being that the current configuration overall has become counter-productive.....

Will defer to others regarding the current case and fans setup. Or other suggestions as applicable.

I did a researach for a best fan config for my case " lian li o11 dynamic evo " and that's the best fan config according to the test but i haven't tried a different fan config.

at 20:08 so i want to believe that's the best fan config and almost everyone is using it as well.
 
What is "best" is seldom quantified in a measurable manner.

Not that you did anything wrong.

It may simply be that the video "best" is not the best for the build in question.

Someone may take note of some difference between your case/fans and the video.

Or another relevant factor with respect to your case and fans. Perhaps the overall build.

Many variables. Some of which (per your OP) do not appear in the photograph or the video.

Do consider other configurations etc.. Continue researching.

In the meantime, hopefully, there will be other ideas and suggestions posted herein.

I just recieved another cooler and it did solve the issue.
 
Is the pump the highest point in the loop?

The key thing to remember when selecting the best orientation for your loop is that the PUMP SHOULD NEVER BE THE HIGHEST POINT IN THE LOOP.

Holy internal tornado Batman!

Well, I guess that's what you have to do with a CPU that pulls an average of 166W. It sure looks pretty, there's no question about that. You did a good job with the look! 😉👍
