How should I configure my AIO layout?

[Yousef65]

I plan to watercool my gpu, how  good will the airflow be if I have a 120mm aio intaking from the back and a 240mm aio intaking from the front with a 140mm fan exhausting at the top? 
 

 

My current setup is a 120mm fan in the top and back exhausting with a 240mm aio intaking at the front.

 

My main goal is to significantly drop temperatures of my gpu, it stays in the high 60s under load which I know isn’t bad but it becomes too hot for me in my room.

 

Case is a thermaltake SPCC matx case with a 3080 stuffed into it.

The room temperature will not change, as the same amount of watts are being used, therefore the same amount of heat will be dumped into the room

I'd replace this with a tower cooler. 120mm isn't enough to really cool.

Turn this into an exhaust

This should be fine

You're unlikely to drop temps any further than this

You will in fact be increasing the temperature of your room by giving the GPU more thermal head room to pull more power and put out more heat.

Hi buddy,

 

You mention AIO's but they tend to be factory fitted to GPUs rather than additions. I think NZXT do an AIO cooler for GPUs but its not very good as it doesn't have any active cooling for anything other than the GPU core. VRMs and memory will need fans. Maybe there's other options but not sure about that.

 

What CPU do you have? Is it cooled by an AIO?

How you configure it isn't going to change heat production. That is a result of power wastage, so the best way to lower the heat output is to undervolt your CPU and GPU. If you can vent the air outside that will help.

I see, I was hoping with a lower system temperature it wouldn’t emit as much heat into the room keeping it cooler for longer. Thanks

I didn’t look at it like that, when you put it like that for me I do realize the error of my thinking there. Do you think it would be worth repasting and repadding my gpu, even if just to drop it 5c?

I was going to just mod an aio block onto the gpu, maybe even make a cheap copper plate that can be cooled by the block for the rest of the memory.

 

I have a 5700x cooled by a 240mm aio, it stays very cool. Around 60c under load; do you think I could swap my aio for a 240mm radiator that could potentially cool my cpu and gpu?

I’ll look up some undervolting guides and do that soon, I’m not really sure how I could vent my exhaust outside, I have 2 exhaust fans. One at the back and one at the top, my best guess right now would be some duct hosing. 

Thanks for the advice.

The temperature will change, but it'll increase. If I pull X amount of power, I'm essentially producing that as heat. So if the GPU pulls 250W, that's 250W as heat. The higher the temperature of the component, the more of that heat energy is contained within the component. If that's our baseline, retaining the same power profile, but REDUCING temperatures on the respective component means that we increased cooling capacity, either by means of changing the TIM, increasing fan speed, etc, which would result in a temperature increase within the room, since that automatically means we've increased our ability to remove heat.

 

TLDR: Increasing ability to remove heat means a higher room temperature with the same power profile.

I see, that makes a lot of sense when I think about it; it would be exhausting more heat from the system.

 

I did some slight undervolting to my cpu and gpu, and I’m now seeing much lower temperatures. My gpu memory temps were 89-95c and gpu temp in general 65-70c, and after undervolting they’re now 76-80c memory temp and 53-59c gpu temp.

 

My cpu went from 55c to 47c under loads. Would I benefit from larger exhaust fans, or even a larger aio?

 

Thanks for the information

Wouldn't that increase thermal headroom and therefore temp?

Would you benefit? No. The temperature in your room will maintain or increase. Will the CPU benefit? Possibly but not terribly likely.

repadding

I never really recommend this. Pads are spendy and fiddly and unless there is a serious problem I tell people to stay away from it. 
Further, anything you do to imprrove performance is going to almost certainly increase the heat being put into the room. This is just a very basic reality of physics. 
Honestly my recommendation would be to get a halfway decent box fan, put it in the doorway pulling air into the room, and be done with it. If you have a window, there are some pretty good window fans with airflow control (in, out, and exchange modes) and that is how I keep my gaming room (two rigs with top tier CPU and GPUs) cool...er. I will admit sometimes the room gets to 92F in the summer even with all my mitigations. Really need to get a guy out here to put in a minisplit
