Please have a look at my setup and advise

I would like your advise and any pointers re my setup please.

I feel both the CPU and GPU are not running as cool as I had hoped for, maybe I am expecting too much?

Neither the GPU or CPU have been overclocked. GPU is a Zotac RTX 3090 Trinity and has an Alphacool Water Block attached, the rad is an EK PE 360 and the pump/reservoir is an EK Quantum Kinetic TBE 200 D5. The CPU is an Intel i9-10850K and cooled by a Fractal Design 360mm AIO. Water temp is 41deg

I have run Firmark for a hour to give you an idea of temps and put other temps in one of the photos. The GPU block backplate gets rather hot but I understand this is quite usual but to me its maybe adding to head build up inside the Lian Li 011 Dynamic case.

Another problem was I used an Asus Z490 Gaming mATX mobo and you can see how tight the backplate is to the IO and memory.

Fan curves for all fans set to 50% up to 50deg then 100%

So any advice or suggestion for improvement greatly received

Edit: I forgot to turn off Furmark and just looked and the GPU temp was 65deg. So Furmark had been running for about 1.5 hours.

Ambient temp is 20Deg

Your temps for your gpu are pretty much what i got when i ran a slim radiator and had both cpu and gpu in the same loop.

My temps vastly improved when i split the loop into 2 separate environments and cooled the gpu with a thick 55mm radiator instead of the 20mm radiator i had before.

My old temps with thin 360 and single loop:

CPU 63c avg
gpu 58-63 avg depending on app


new temps with dual loop and thick 55m 360 radiator
CPU 55-58c avg
gpu 45-48c avg depending on app

Backplate gets extremely hot, burns your fingers if you held it there for more than a few seconds. I would advise getting a fan over it or use a ram block to cool it down as some others have done.

So do you now have 2 x 55mm thick rads and 2 pumps/reservoirs

I was thinking about one of these for the backplate - https://mp5works.com/ - but this will also mean replacing the mATX mobo with an ATX one to give me clearance. Maybe a RAM block would suffice?

I have 1x55mm at the bottom and a 30mm at the top both of which are independent and in their own loops.

The mp5 is an interesting take on it but would still prefer an all in one solution tbh like the Aquacomputer XCS active backplate cooling.

A ram block would suffice, someone over on the evga forums did a mod with a EK ram block and manage a few degrees cooler on the gpu temps.
 
@Petrolhead flip your fans on the bottom rad you will get better temps for now

ideally u need thicker rads 54mm max top and side with low fins per inch so u can use fans at lower speed and 3 fans as bottom as intake a single loop will give u better temps.

Those thin rads are no good for your heat load.

edit. Also increase fan speed till it u can’t hear them set that as your min speed. Increase pump speed to about 70%.

edit 2. Should have gone atx as the first slot is pice x 1 then the pcie 16 it would be worried about the back plate transferring heat into my memory. It’s as tight as a nats nacker

So your saying the ek pe 360 is too thin?

what rads would you recommend? I am concerned there may not be enough room for a 54mm rad top and side in my case?

if going your route how would you set the rad fans up, blowing in or exhausting out?

I think your rads are fine. Not sure about the static pressure of those fans but with a higher fin density like the PE you need good SP. More especially so if you were to go to a thicker rad.

I am an advocate of the thickest rads with the lowest fin density. Running 2 x 480mm x 60mm rads in mine lol... Lowest fan speeds possible.

Those bottom fans are pulling air through the rad yes?
Better pushing but only marginally, flipping the fans as mentioned above will mean pushing hot air down, just fighting physics for the fun of it. In from the front and bottom, out through the top and back is the most effective.
 
@Petrolhead yes the pe 360 is way to thin.

I currently use 2 360mm x 54mm they are Black Ice Nemesis LX360 OEM Builder Edition these are just the same as nemesis GTX but like 30 quid cheaper

you have only one option for the side and that’s up to a 360 mm x 54 mm fans exhausting

the top is also the same.

now the bottom u can use up to a 360 mm x 60 mm fans exhausting

So the it’s

1. top with fans exhausting and side with fans exhausting , bottom intake. Coolest ambient air in smallest rad area.

2. Top rad with fans exhausting and bottom rad with fans exhausting. Side intake. The most rad area.

3. Top intake with bottom rad and side rad fans exhausting. may pull in slightly warmer ambient air again most rad area.

you won’t be fighting physics as long as your blowing cooler air through a radiator you will get heat transfer

read some of the rad reviews then go compare the prices on line

I thought there were problems have rads in the top and side of the 011 dynamic found this - https://www.reddit.com/r/watercooling/comments/8mb3lz/warning_lian_li_o11_dynamic_and_360_rads/

the ek pe360 fin density is 38(19 split fin). Not sure what that means. Its 38mm thick but thats the casing. The core is less due to the clearance between to core and case, never measured it tho

the next one up is the ek xe360 fin density is 16. Its 60mm thick and concerned it that may be too thick

alternatives are Alphacool xt45 fin density is 12. Its 45 mm thick, then there is the Corsair xr7 fin density is 13. Its 54mm thick

Its all down to what i can get fitted en in the case.

i think your right re the fans on the gpu rad. They are 658-1800rpm, 47cfm and 1.6mmH2O. I think the EK Vardar Evos may be better, 550-2200rpm, 77cfm and 3.1mmH2O

thoughts?
 
I'm not sure how we concluded the 360 is necessarily the issue.
Temps aren't obscene, and it only has the GPU in the loop.
Get some proper fans and go from there.
I was basing my post re rads on your statement “I am an advocate of the thickest rads with the lowest fin density” and if i decide to add the cpu into the loop and ditch the aio what my rad choices are
 
Ek Vardar vans are good but u will hear them over 1000 my eloops are quieter

best are artic cooling sp12’s but they fugly good

I have all three

my old build
https://flic.kr/p/2jYam7J

Now ignore the front fans as u don’t have the air but get the space they take up

and you have a slightly smaller res that’s mounted.

Here are my rad dimensions they where tight but if u flex the case slightly they just go in the side

398mm x 120mm x 53.6mm (L x W x H) these fit top bottom side

What are you trying to achieve?
Quieter?
Cooler?
Or futureproofing?

Yes low fin density thick rads are the quietest I have found but you're far more limited on space.

Better fans on the PE 360 may well get you where you want to be.
 
coolest is my goal

yes agreed better fans on the 360. But if going to add cpu to the loop then i will need another rad so looking at that as well
 
Your ek needs high static fans with that fin density sell it on.

the other rads u mention need 1000 rpm and below

I’m pretty sure I saw some rads for sale on the mm
 
Just another point, may or may not be relevant. The side fans are blowing in. With the current setup, but with better bottom fans, should i leave the side fans blowing in or exhausting out?

if i was to go hlennie’s rout and exhaust the bottom fans should the side fans then blow in?

Go for the Vardar they still shift a fair amount of air and they should not be too noisy with low fins up too 1500
