Question What airflow would be best for my case?

[portalbreaker]

Hello.

I am very unsure how I should ventilate my PC. I have heard so many different opinions. I also heard this specific CPU gets very hot and so the AIO should pull inn air.
Room has normal temp of 22 celcius or 71 fahrenheit. No carpets, minimum opertunity for dust buildup.
The PC is gonna be primarely gaming.

Motherboard: MSI B650 Gaming Plus WIFI Motherboard
CPU: AMD Ryzen 7 7700X
GPU: ASUS RTX 3070
RAM: G.Skill Flare X5 DDR5 6000mhz 32GB (16GB x 2)
AIO cooler: ID-Cooling FX280 PRO SE
PSU: ASUS TUF GAMING 1200G - ATX 3.0
Case: Fractal Design Meshify C Temp G
Casefans: be quiet! Silent Wings (both 140mm and 120mm)

Red = EXHAUST| Blue = INTAKE (6 pictures)

Thoughts?

On the radiator, switch to exhaust.

In the front, out the top/back.

Why C and not B?

Ah...did not see the A B C D E F.

B.

C D F brings the possibility of an air bubble at the very top of the loop

Don't apologize for the diagrams! Probably the best illustrations I have seen here. FWIW you always want to exhaust air from the rad, otherwise you are warming intake air that will now be used in an attempt to cool a big fat, high wattage GPU. B is the most straightforward and common set up. It also places the AIO pump at the bottom of the system which, as in anything hydronic, the safest place for it.

I would probably find a different case that one only fits a 315mm video card.
Ran out of room in the one I had so I had to replace it.

Those are GREAT visuals.

a front mesh case ,with 2-3 intake fans.. and and aio on top 240,280,360 with fan on exhaust . and 1 back case fan on exhaust.

Why C and not B?

B exhausts hot air from the gpu and system through the radiator, decreasing its effectiveness. C draws in cool air from outside the case to maximize the radiator's cooling.

That is not a 100% settled discussion.
Good points either way.

Mostly, you want the air to move through the case. Not just blow around inside.


In all of my systems that had a top mounted rad, it was exhaust out the top. With no ill effects.

A: No. The gpu cooler isn't a blower type. If it were, you could at least cool the backside of the gpu. This set up doesn't work well with most axial fan cooled models.
B: Yes. The widely accepted jack of all trades.
C: Yes*. Be mindful of the position of the joint where the hoses and the radiator meet. If it is the highest point of the loop, it will make some noise after 2-3 years, due to the fluid level having decreased. If the AIO is refillable, you can fix that.

D: No. Same as Example A.
E: No. Fans too close to one another operating in opposing directions creates an airflow loop. The 2 AIO fans will recirculate air.
F: No. Same as Example E.


The gpu fans in the diagrams should be blue instead of red, but oh well...

The GPU is often not only the highest wattage component, but also the most likely component to see maximum continuous use at TDP. In configuration B only the CPU (bursty load, often not at full utilization) gets -some- preheated air, in configuration C all intake air is preheated. The difference is probably negligible in practice but B is the most efficient set up, with the addition of having the pump in the AIO positioned better. In short, Heat travels faster the greater the TD. B gives the greatest TD to the most components, with preference to the largest heat generator (the GPU).
