Lian Li O11 Dynamic Evo vs Corsair 5000D Airflow- RTX 4090 OC, Ryzen 7900x

[MainManStrider]

Hi All,

I am looking for some insight as to how to better cool my furnace.

Currently, I have a Gigabyte 4090 OC and a Ryzen 7900x combo. This is currently in a Corsair 5000D Airflow. I am looking for some insight as to better cooling.

I have 10 Corsair SP120 fans and an H150i (360mm) AIO. My PC is running at around 70 degrees on each GPU core and 80-90 degrees CPU when playing games.

This is producing a huge amount of heat and making my office incredibly uncomfortable. I was at Canada Computers today and they suggested potentially changing cases to something that can intake from the bottom of the case and the O11 Dynamic seems to do that with the same quantity of fans. I was hoping to get input from the community on which case is better or how to help my rig cool down. I have considered water cooling but dont want to sink a thousand dollars into my PC. I know my PC sounds expensive which it was but I got it heavily on sale (4090 was priced wrong).

Thanks,

You do realize that changing the case would not improve your room temp right? If anything, it would only improve the temp of the components and inside the case.

The key factor here is the heat producing component, not the case.

So, just undervolt or undervolt and set a lower power limit, this will reduce power consumption, therefore less heat.

sounds like its the room temp is the problem. the o11 might make the gpu ever so slightly cooler but cpu temps might be higher. 

 

water cooling would just make the room hotter thow an option to say put the rad els where to dump the heat.

First of all SP120s are weak.

 

Second, we need the specs of your system.

 

Third, please share a

diagram showing where all your fans and AIO are located, and the direction of airflow for each. 

 

What is the room temp when it's off? Do you use A/C? With OCing, you may need it. 

 

Are you undervolting? That can drop your temp. 

 

Finally, depending on your computer, there may be better cases, such as all-mesh. Lian Li is good sometimes but pricey. 

 

Waiting for your answers.

Are you sure that's necessarily true? If the OP can cool it better, the temps won't get as high as right now, wouldn't they?

the better the cooling the hotter the room will get as there not as much stored in the aluminum block. called heat soke i think? its when an object cant hold the heat. has to do with mass.

 

other then lowering voltage that would make it cooler but how much and that will just give more time and will most likey still heat up to uncumfy temps.

The benefit I most like about my Lian Li 011 Dynamic Razer Edition case... yes I know it predates the EVO cases... is the headroom above the motherboard for placing radiators or AIOs. That was a deciding factor for me in selecting the case 3-4 years ago. My previous case, a Corsair Carbide 400R, could fit up to a Corsair Hydro H115i ... if I jammed everything in and cursed to the high heavens. I couldn't access the AUX CPU power cable at the top of the motherboard, without partial disassembly of the computer.

I find most cases with provision for Radiators or AIOs have this problem of insufficient headroom above the motherboard. One thing my case could have is a little more room ... about a half inch... below the motherboard to the floor of the case. It would allow room for more bottom fans when you have cables connected to the bottom I/O of a motherboard. In the way is my front panel I/O and USB3 / USB2 & HD Audio connectors. Otherwise, I am happy with the case.

You do realize the better the cooling the PC has, the more heat are being dissipated by the case fans right? It's simple logic.

When the CPU/GPU are being cooled, where do you think the heat is going? Magically cooled down?

The case takes in cool air, and exhausts hot air, the better the cooling the more cool air taken and hot air exhausted by the case. Basically converting cool air into hot air, a space heater with more function.

I respect your contributions here, Duke, but to be condescending by suggesting that I'm engaging in magical thinking or similar rubbish is offensive.
