Would these bottom fans help exhaust the GPU heat?

Hi guys!

 

Before anything, here's my config:

-5800x

-liquid freezer ii 360

-lian li lancool 216

-3070

 

So my idea was to keep the 2 front fans as an intake, set the top-mounted AIO fans as intake too, keep the rear fan as an exhaust (in case both this fan and the AIO cooler can fit) and, of course, the fan of the PSU as an exhaust (see the picture below for reference).

So here's the situation: I managed to find 2 additionnal fans, and I thought about adding them at the bottom of the case, as an exhaust, to evacuate the heat directly from the GPU.

Do you think it's a good idea to proceed this way? Would it be better not to place bottom fans at all?

 

Thanks for your answers!

PSU leave as it is. Put all going in and the one on the back as it is.

Will the air coming from the bottom fans interfere with the GPU fans and cause some malfunctions? Like overspinning or just making the gpu fans stop?

Nope. I wouldnt, keep it as is.

 

Id rather have the gap for air to flow from intake to the rear holes of the case. Also, your PSU fan diagram is wrong, it intakes from the dust filter and then exhaust to the back.

First turn your aio fans around as exhaust fans and turn the bottom fans as intake to give the gpu more air. And keep your psu as is

I feel like everyone has their own vision of what's the best fan configuration. Makes it kinda hard to choose one and who to believe :')

As @SorryClaire said, it won't make much of a difference if you put the fans there or not. But if you have them as exhaust (the fans on the bottom) then you'll be taking air away from the gpu intake. If you already have the fans then put them on the bottom as intake. If not then just keep your config as is but turn the aio fans around as push exhaust

Thanks everyone! So here's the updated picture that takes in account everything you folks told me. Do you think the temps will be good with this setup? 😄

 

@SorryClaire I know you said you wouldn't put those bottom fans, but as shown below, do you think these fans would be useful, even if the improvement would be really minor?

I would just do without them, they aren't going to improve things. Just adds more sound to the case and I wouldn't be surprised if it made thermals worse (the rear one anyway). The one at the rear has no room to pull fresh air, so it's literally just grabbing whatever it can from a PSU that's generating its own heat.

 

I would just keep them as spares.

SImple as this, Psu is the psu leave it original. Now the Top rad you want fresh air so they will put air in, front fans will put air in, Fans down will feed the gpu with fresh air and they will make the air go up and into that read fan that will take all air out , you will have positive presure so dont worry. I have been doing builds for very long and I can say the more air going in the better.

Thanks! Unfortunately, after noticing the small length of the fans cables that I want to install at the bottom of the case, I won't install them. But I'll keep your suggestion:

- AIO and front fans= intake

- rear fan= exhaust
