Do I need more fans?

[CiprianB]

Hi,

 

I have a Corsair 7000d with an Arctic 420 AIO for the CPU. The cooling configuration is the following:

- AIO 3x140 mm fans exhaust on top of case

- 2x140 intake in front of the case

- 1x140 exhaust on the back of the case

 

Is this okay? It seems I have more exhaust (4x) than intake (2x) 

Also, how does the GPU's 3 fans paly a role into this?

Should I get some more fans?

 

PS. Here's the full config:

- CPU: 7950x

- GPU: 4070 Ti

- AIO: Arctic Freezer II 420

- MB: x670e-f

- PSU: hx1000i

- Case: 7000d

- RAM: 2x32 DDR5-6000

- SSD: sn850x 2TB

 

 

Kind regards,

I'd move the AIO to the front, and the other 3 stock fans as exhaust. If you have more exhaust than intake, you'll just pull in air and dust in through cracks (or where it can move the most free, like PCIe slots) and the CPU will not get hot air from the graphics card. The GPU won't change much in clock speeds and temperatures, since the radiator is so thin.

 

Have a look at this video and see top rad + open card and front rad + open card temperatures. (video starts comparing top radiator + open card and front radiator + open card) All temperatures at 12:08

Speaking from performance stand point, it should be fine, tho your case would have negative pressure, as in more air are being pulled instead of pushed. Which might affect the dustiness of your case, fine dust would get in easier than if it has more intakes.

Or just move the AIO to the front and configure as intake, then 3 exhausts.

It's already pretty well ventilated, but negative pressure is bad for dust

Add a front intake fan to balance that

You can also play with fan speeds to have front fans running faster, back fan slower

The case hase the possibility to add further 1x140 intake in front and 3x120 near the front, on the side. 
Shall I do that? Or shall I do that and move the AIO in front as well?

Or just move the AIO in front, as suggested and have 3 intake - 3 exhaust?

 

Kind regards,
