AIO position and Nvidia FE GPU findings

[greggo87]

Just thought I would post to see if anyone else has found themselves in a similar situation and share my findings.

Case: be quiet purebase 500dx
CPU: Ryzen 5 3600
Mobo: x570 taichi
Ram: 16gb 8 pac 3200 cl14
Case fans: 2x noctua NF A14. 1x silent wings 2 140
AIO: lian-li Galahad 240
GPU: 3080ti FE

So basically I had a 2060s until recently. Case layout was 2x noctuas as front intake, my aio top mount exhaust and my silent wings rear exhaust I would get great GPU temps and CPU never above 60c

I recently upgraded my 2060s to a 3080ti FE and while my GPU temps were good (60ish) my cpu temps would go to 75c under load which had never happened before. Putting my hand above the rad was basically like a hairdryer blowing air and even gf commented that room was way hotter than usual.

So today I decided to swap my 2 noctuas to top exhaust and my AIO to front intake and low and behold my GPU temps have stayed exactly the same meanwhile CPU temps are now 47-50c under load which is 25c less than before.

I can only assume this is because my 3080ti was exhausting hot hair directly up into the AIO causing the liquid temp to rise, causing the CPU temp to rise and round and round it went.

Amazing moving it to the front made such a big different. If I had had a higher TDP CPU I have no doubt I could have been getting close to 100c.

Curious to see if any of you with top mount aios or air coolers above a 3080, Ti or 3090 have experienced anything similar or different to this?

Very interested in this as I have similar, the temps on my CPU have risen since getting my 3080 FE yesterday and my room is now boiling! Mrs made similar comments as yours...

I only have the stock wraith cooler at the moment, but considering investing in an AIO for 3600XT I have as I'm not sure how comfortable I am leaving things as they are with prolonged gaming sessions...

Love the gf/missus comments! From experience.. they like it hotter than males no? Bonus for them!

I have AIO and a 3090. I went from a vega56 and not noticed that much difference. The likely reason being I have a 4k monitor which the vega would not have liked very much beforehand, but with the 3090 the cpu is not so terrorised!

What res+hz are you gaming at?

I guess a mix of the FE cooler design and the large power requirements lead to some interesting results when they are in a case.

I wish I could help more as I do have a noctua NH D15 around and I was going to try that and see what effect the 3080ti had on it but I currently have no spare thermal paste left so just moved my AIO radiator instead.

I know the wraith cooler is only ok to begin with as I had one too initially but if you can afford it I would get an aio if you can front mount it or a decent air cooler if you can only top mount am aio

Haha I mean she is always colder than me and likes the heat so the fact even she commented on it was the final straw that made me decide to swap things around.

I have 2 monitors a 3440x1440 144hz ultrawide and a 2560x1440 144hz secondary monitor

Cheers for that. Already been reviewing which AIO to purchase

Being my first time looking at AIOs, how have you got your fans positioned? I only have a small-ish case (Thermaltake Versa H15) and was looking at a few reviews last night.

I'm thinking (if it'll fit) to have the fans/AIO configured as follows:

Front Case > Intake Fan > Rad > Exhaust Fan > Case Internals > Exhaust Fan at rear of case & 1 on top.

A lot of people I've seen have:
Front Case > Rad > Intake Fan > Case Internals > Exhaust Fans at rear of case

Thoughts?

I'm also gaming on a 3440 x 1440 at 144hz (now I have a 3080FE, mainly with everything maxed out )

Did a quick check of the case specs, I would probably go:

2x 120 intake > rad > internals > top 120 exhaust> rear 120 exhaust

When you said intake>rad>exh did you mean push pull on the 240 rad? Because from testing (various YouTube videos about this) the extra 2 fans on back of rad make little difference to overall cooling so would just stick to the layout I suggested. Can always try adding another 120mm exhaust top if 2x top will fit to see how it affects temps.

That's awesome, thanks for the advice.

The push/pull on the 240 rad was exactly what I was looking at, but that makes sense, will do what you suggested and see what the results are

No worries glad to help. I know you said you were researching aios.

As much as I like my Lian li galahad 240 I mainly got it because it was white and I have a white case. If I had your case I would go:

Ek 240 basic - all black no RGB but great cooling
Arctic liquid freezer ii 240 - non RGB but again great cooling.

Both of the above also have RGB/A-RBG variants for a little more money too if that is your preference.

I sit there in shorts and t-shirt, meanwhile gf is in wooly PJ bottoms, hoodie, throw blanket, massive socks and still says she is cold.

They really are cold blooded to the point I may as well just put a big rock in front of my living room window for her to bask on.....

 

[SentineL-X]

Cheers for that @greggo87 !

Gone with the Arctic, so will see how this helps the CPU temps, ill have to think of a more permanent solution for the room and the Mrs

Good choice. I think the Arctic is a bit cheaper than the equivalent EK. EK is supposedly easier to install the block (easiest on market perhaps) but Arctic is decent too. Once installed both trade blows with one another so can't really go wrong with one or the other. I think Arctic also changed the warranty from 2-6 years so also decent on that front too.

Have to let me know how temps look once all is installed.

Dont get me started. Wife has heating on then by time I realise im a sweaty mess. She wears jumpers etc, makes me hot looking at people like that!

Right, so fitted my AIO today (wow, what a squeeze that was in my case!).

Temps on the CPU are amazing, down to 35idle now and on the quick test I did on COD:WZ earlier, the GPU temp was lower as I presume the ambient temp was way lower in the case too!

Set some custom fan curves for the exhaust fans now as well based on the Memory Junction temp, which seems to be much better
Thanks guys

I have 2 intake fans, one rear exhaust and a Corsair H100x exhausting through the top.

My 3080ti peaks under full load around 64-65c, and the CPU in games around the 50s and 60s and idle (or low usage, like spotify, internet and discord) is around high 20s and low 30s.

Is yours an FE as well or an AIB card?

Nice one mate, glad it helped. I can game for hours on end and because the overall temp in the pc is lower it's exhausting lower temps into the room as opposed to hotter air with higher fans to keep things cool so my room temp is nicer too.

Sorry, its a AIB (Gigabyte) card.

Previous experience with a 3090 Palit, while on air, not only the AIO at the top would be affected, but also the RAM. Not enough to cause issues, but a good 15C to 20C increase (got a temp sensor at the RAM). Also the heat that irradiates from the back would increase the X570 chipset and the NVME/M.2 temperature.
Same issue with a previous Vega 56, Sapphire Pulse.
The optimal layout, unless going down watercooling, would be PLENTY of airflow, but balanced.
For the popular O11, bottom and side intake and top exhaust should do.
Rear exhaust would help exhausting some of the warm air from the GPU before it all reaches the AIO.
The main issue, specially with the 3090 is that, under full load, without any mods, the back will run hotter than most people will be comfortable with.
Not uncommon for people notice their fans going nuts even if the GPU temperature is fine.

As for OH's comments, yes, a constant nagging about how the room was so hot. And it was.
