[SOLVED] How should i have the airflow?

[rochismo]

Hello, i have recently purchased the MSI RTX 3080 Ti Suprim X and i am seeing something i haven't really seen before with my AIO.

Currently i have the Lian-Li O11D-XL with a fan on the rear as exhaust, three fans at the bottom as intake, three fans on the side as exhaust and three fans on top along with the AIO as exhaust.

All of the fans are Corsair QL120 fans except for the AIO which are the Corsair ML120.

The thing is, previously i had an RX 5700 XT Sapphire Pulse and the AIO liquid coolant seemed fine while gaming and having the GPU sitting at 80ºC and it only got up to 37.40-38.90ºC. But the thing is that with my new GPU after 10 min of playing the coolant temp got to almost 50ºC.

What could be the culprit there? Is there any danger of having it higher like that for long periods of time? Should i purchase some fans to make a push pull setup?

Currently putting the AIO on the side is not an option for me because i do not want to get into the hell of cable management again (at least not any time soon). I could bear with adding three more fans to make it push pull though.

• CPU - Amd Ryzen 9 3900X
• PSU - Corsair RM1000x
• AIO - Corsair h150i Elite Capellix

Thank you in advance.

Edit: The GPU on idle is around 41-46ºC and on load it's around 68-75ºC
Edit 2: The concern in this question is about the AIO coolant temp, it ramps up really quick when i play any game that makes my GPU run hot. All fans (except for the AIO) are running at 1500-1600 RPM

Anything below 85C on a GPU is perfectly fine. In fact, stock behavior will adjust fan speeds to maintain 75C, so what you're getting is completely normal.

I'd recommend balancing quantity of intake/exhaust fans more. Of course it depends on fan size and rpms (and fans won't push air through a radiator as well), so it's more balancing intake/exhaust CFMs. You generally want to shoot for slightly more intake than exhaust.

Sorry, i didn't mean the question for the GPU temps, i meant for my AIO coolant temps.

QL120s are not very strong fans. More flashy than other RGB fans, but Corsair threw performance out the window to pull it off.
Those QLs at the bottom likely aren't doing jack: that's the area of the chassis with the most airflow resistance present.

Assuming the 3900X was still present before the gpu change:
Sapphire Pulse 5700XT: 180 - 195w board power limit, depending on the bios used.
3080Ti Suprim X: 440w board power limit.
Energy use = heat. There's potentially more than double the power draw here.

Currently putting the AIO on the side is not an option for me because i do not want to get into the hell of cable management again (at least not any time soon). I could bear with adding three more fans to make it push pull though.

Then change the AIO to top intake. Push-pull will do nothing.
It actually worked for another user here who was experiencing BSODs due to thermals. They had a similar setup to yours: 3900X, Kraken X62(top exhaust), and 3090 Suprim X.

[SOLVED] - IRQL_NOT_LESS_OR_EQUAL BSOD and PFN_LIST_CORRUPT BSOD errors during gaming

I ran WhoCrashed to check the bsods and here is what it shows: View: https://imgur.com/a/1wCiK8v In the conclusion section in WhoCrashed it said "6 crash dumps have been found and analyzed. No offending third party drivers have been found." I got the PFN_LIST_CORRUPT BSOD error after about...

Just too much heat coming off their 3090.

I will try to put the fans on top as exhaust a bit later. Meaning that the fans will no longer be drawing the hot air from the GPU. Also, should i make the side fans intake instead of exhaust?

No. Change the top to intake.

On the plus side: remove the QLs at the bottom, and let the gpu's fans take care of bottom intake. The static pressure from them is going to be higher, and it also can access air from both the bottom and rear.
The QLs will just get in the way of the gpu fans.
Consider removing the rear PCIe covers for better airflow. It's not filtered anyway, so it can only help... unless you have small pets or curious kids around.

I have set them as intake at the bottom of the radiator. I don't know if it did help the coolant temp at all or not. By that i mean that the fans of the radiator are blowing the radiator air directly to the GPU. ¿Is that the way you meant it?
Edit: After running the witcher 3 that makes it use the entire GPU potential for around 10 minutes the coolant temp got around 38ºC and after a while the temps of the coolant get around 4-5ºC lower than when i had the fans as exhaust, but also the coolant temps seemed to not want to stabilize while my gpu was under load

This one slipped my mind, but is the pump speed maxed out, or set to extreme in iQUE?

That's why the rear and side are left as exhaust. It's a weird looking sandwich of sorts.

Yes the pump is always on extreme profile.

Edit: Currently it looks like this, is this how you meant? Image

Then it's likely the aggressive nature of Ryzen 3000's turbo boost. Ryzen 5000 is even more aggressive with it.
Liquid coolers 'soothe' the spikes, but they can't stop them completely.

Yes, i have "tamed" it down by undervolting it to 1.1v and clocked to 3.9

I also have added a picture on how i did put the fan setup. Just to check if it's how you meant, in case you didn't get to see the pic https://postimg.cc/w7g3CqM4

 

[Phaaze88]

Yeah, that's what I meant in the pic.

A small correction from previous post. It's a combination of Ryzen 3000(and up) turbo boost algorithm, and the layout of the chiplets under the hood(IHS).
They're not directly in the middle, where coolers are mainly focused

Well, i have been running furmark for a while and the temps of my gpu seem to oscillate between 77-81ºC.. ¿Is that normal? ¿Is that safe for the long run, like 5-6 years?

Normal? ~Ehh, not really, no.
Furmark is an extreme case, but it is useful for testing the capabilities of the gpu cooler. You won't see it sitting around temperatures like that all the time in game.
Think of it like Prime95, but for the gpu cooler.
With a result like that, I'd say it's good.

Is that safe for the long run, like 5-6 years?

That's fine.
