For fun I have designed a new PC cooling, when I could start from scratch down to completely new component layout for the mainboard.
Todays cooling system lacks on two different Airflow direction, one from front to back and one from bottom to top which influence each other. cool air that’s pushed in, can directly pulled out from another fan. Large cards like the gpu, act like a blockade for air that wants to get from the bottom to the top
Here is the design: There is only one air direction that works with the thermodynamics; from bottom to top. GPU, CPU Cooler and all PCIe cards are installed vertically in the air-flow direction. the CPU cooler also draws in at the bottom and blows out at the top.
At the bottom on both sides are the air intakes and behind one big pocket fine dust filter. Ventilation silencer (a kind of sound absorption box) can be fitted at the top of the case after the pull out fans (not shown in the picture). What you think of this?
You can do barries optionally but as less resistance is inside, the quieter the air noise and the whole case is flooded, thermodynamics does the job when components are hotter there also more air gets moved. RAM must be also positioned vertically on the mainboard, not as in my Image shown. So the complete mainboard has to be redesigned. There is one big problem; connectors of PCie cards are then on top, or cables can be used to bring it to the rear.
We have this already, more and more cases have bottom fans, but there is the gpu as big barrier, and behind the GPU you have lack of cooling and CPU Cooler + Rear Fan pushes into other direction. This two direction airflow is the problem of existing cooling.
Yes, that’s a problem with the motherboard in your diagram, the RAM being oriented 90 degrees to the airflow and being above the CPU. Could you rotate the board to put the RAM at the bottom? You’d need to use a taller case, and have some means of making the “rear” panel connections from below.
My dream cooling solution has more to do with an automated system that pulls air from outside if it’s colder outside, and pumps air outside if it’s hotter outside. This would include valves that open and close.
As people who know more about computer cases than I do say: “Once you have fans blowing air around, gravity makes no difference.”
I don’t think the open motherboard has to be part of it. That is similar to the setup I will have if the desk ever gets complete.
It’s a fairly insulated room with a mini-split, but it will have two high power computers and a number of others like laptops for other things.
Cooling compressor that produces cold water was also used, but you can’t see this often today. Some crazy people have their entire mainboard with graphics card in an aquarium filled with oil
