Fan Setup for Lian Li O11 Dynamic
Components:
8700K
NZXT x72
2080 Ti (Strix/FTW3/Trio - TBD)
6x Noctua Chromax (F12 if radiator, S12A if case fan)
3x Corsair LL120 White

I'm trying to figure out if it'd be possible to set up my fans in the Lian Li O11 Dynamic in order to allow for side exhaust (because LL120 aesthetics) while maintaining good thermals and positive pressure.

The only setup that seems to fit these requirements would be top/bottom intake + side exhaust, with radiator either as top intake (probably in pull) or side exhaust.

If I place the radiator as top intake, I'm worried my GPU may run warmer than I'd like, especially since the 2080 Ti can get pretty toasty.

If I place the radiator as side exhaust, I'm worried whether LL120s will be good enough at dissipating heat, since they're really nice aesthetically but not as performant.

Any advice on which setup might be better? Or would I need to go bottom/side intake + top radiator exhaust in order to maintain good thermals? Ideally hoping for sub-70 for CPU and GPU.

Thanks!

Don't intake from the top, hot air rises.

If you want side exhaust, then you put the AIO on the side for exhaust (won't cause that much hotter temps), and set the fan speed to be lower. Then put the noctua fans on the top and bottom of the case, make the bottom ones spin faster, and the top ones spin slower. (If I'm not mistaken, you can set speeds for individual speeds for fans in the BIOS, I'm not sure, never actually done it.)
This should result in positive pressure.
(Plenty of air cold air should hit the Rad, and keep temps low for the CPU, and hot GPU air should just be exhausted out of the top, and at worst, you have to turn the fanspeeds up on the AIO, and get neutral air pressure, or slightly negative air pressure.)

Just remember, where you're exhausting, take the dust filter off, as it will stop airflow, causing the Rad to get hotter.

And, Corsairs LL120 fans are pretty good at airflow, so I wouldn't worry to much about how much they can move, in most cases, it's more than enough.


I don't have any experience in this case, although I have thought about getting it, and wondered the same thing, this is the solution I came up with.

Escorve or Tacoshy should be able to help better, since they have experience in the case, if you wait, they should reply.

Well, the hot air rising ist really an issue in a pc case with even minimal airflow.

The ll120's are pretty good performance wise also, I've got 9 of them sitting on my shelf waiting to go in with a custom loop, I'll be sitting them all as exhaust for looks and raw performance (negative pressure can offer a tiny advantage over positive, at the cost of dust), I plan to add a filter to the rear of the case to help prevent this, just make sure you have some way to actually power all of them, a friend just built in the air version and overlooked this so only has half of the fans hooked up.

I have an O11 case and I run 6 LL120s (3 bottom intake, 3 top exhaust) and a H100i platinum AIO as side exhaust and works great.
sawdust3d 2019 年 5 月 16 日 下午 8:54 
I actually added 1x120, 2x80mm and 2x50mm fans to the 9x120mm you can fit naturally.

There is so much fan space in that thing you can make the air do whatever you want.

I'm pulling from the back and side, exhausting through top and bottom.

Running through RADs on all 9 fan spaces. Just needed the extra intake for dust prevention, 6xexhaust is tough to overcome.

The case gets full quick though, especially the cable management area.

Sorry to go off topic a bit here...

Sawdust, mind showing a pic of your whole setup, still part collecting for my loop, need the blocks (not out) and pump/res still, seems to be very few people going with 3 360mm rads (even less with a card as outrageously huge as the ftw3) , I THINK I've got my measurements right, going with a 45mm in rear section then a 30mm top and bottom, gpu needs to be vertical mounted HIGH to fit and infact needed a 2 Slot adaptor, I've got a front distro block also, but, honestly unsure if it will fit at this point with the rest lol.

Having some bsod issues right now do my build is on a small hold til I figure it out, it's either nvme boot drive, ram or vram, all things I want fixed before I watercool it heh.

I would also like a picture of Sawdusts rig.

I

Will do, I'll make a new thread when I get home from work this evening. Don't want to totally Jack OPs thread.

I had some weird NVMe/boot drive issues that had to be sorted out.

Have a great day all

Edit, deleted unneeded sentence.

I run 3x LL120 at the bottom as intake, 3x LL120on the side as exhaust and 3x LL120 on the AiO on top as exhaust. To cover up the ugly backside of fans I use fan filters.

https://steamcommunity.com/sharedfiles/filedetails/?id=1583121119

Dustfilter really doesnt stop the airflow. Unelss you sue super thick dust filters the fans are easily capable of pushing through it. Also 120mm fans have higher static preasure then 140mm fans which makes a passthrough even easier then it already is.

the LL120 perform just fine. The HD120 are to bright for me. Actually even the 120 are to bright for me as I needed to replace my Lian Li Strimer RGB ATX Cable as you couldnt see the RGB on the ATX cable as is was oevrlighted by the LL120 fans.

thanks! yes tooked me a while got to many reanimations going today :(

Thanks everyone for the feedback!

re: hot air rises - the things I've read suggest that while top exhaust is nice, in practice the difference is minimal since the airflow created by the fans will be more than enough to overpower the natural tendency for hot air to rise, so I haven't worried too much about maintaining top exhaust.

Good to know LL120's are at least reasonably viable as radiator fans - I was primarily worried whether the static pressure would be too low, since I didn't want to run them past 1700-1800 rpm or so. I think I'll try out top/bottom intake + side radiator exhaust first, and if that isn't satisfactory I'll take a shot at bottom intake + side/top radiator exhaust while fiddling with fan speeds, and if temps are still high I'll just surrender and do side/bottom intake + top radiator exhaust.

Good reminder on no filter when exhausting; I'll definitely need to keep that in mind.

Good reminder on making sure I can power all the fans as well. I'll be using the Z390 Aorus Master, which I think should have enough space since CPU_FAN should cover my pump + radiator fans and the 6 SYS_FAN headers should cover my other 6 case fans.

I did see the Hardware Canucks video, but unfortunately he didn't test top/bottom intake configs ):

Also sawdust that's a truly wild number of fans haha. I think I'll probably stick to 9, but I'm curious to see your build as well!

Edit: just saw taco's post. Nice build and thanks for the photo! I originally wanted to do bottom intake + side/top radiator exhaust but was worried about negative pressure since my room can get sorta dusty sometimes. Might try playing around with fan speeds to see if I can get it to work though because it's my favorite config so long as I can keep the dust out.

I do a dual intake, the rear of the case used for exhaust(normally) is now an intake with filter for 120mm RAD, front of case is intake as well 280MM rad, and one exhaust on very top of case, all noctua fans. So only 4 fans, and very quiet.
tacoshy 2019 年 5 月 17 日 下午 9:27 
Yeah my fans constantly run at lowest speed. The NZXT Kraken has to be connected to the CPU Fan header. Only to tell the motherboard that it has a CPU cooler as some motherboards won't boot otherwise. Made already a video where I proofed that removing the cable while it runs does nothing.

The fans for the radiator itself will be connected to the AiO directly. Stock fans should be replaced as NZXT Aer P fans do really suck.

What I personally would recommend for the 6 case fans is a Corsair Commander Pro. This is a Fan Contoller with RGB Software interface which you need to control RGB from windows. Otherwise you'll need a Corsair Lighting Node which has also 2 RGB Headers but not those 6 Fan headers.

Also you need at least 2 triple packs that come with a RGB hub included.

Hey I know its an old post but I'm having the exact same problem as you. Just want to know what configuration you went with. I'm particularly interested in Top aio intake bottom intake and side as exhaust.

Hi - new forum poster, and very new to the o11 dynamic. Set it up at the weekend and have benchmarked performance and thermals. What I've found so far...

I have 360mm Gamer Castle RGB v2 AIO in side config. 3x 120mm UpHere fans pulling from bottom, and 3 pushing through the top as exhaust. At first I had air being pulled from inside the case through the AIO, but I have an RTX 2080ti OC 11g Gigabyte card, which is blower style. All hot air was being sucked through the AIO as opposed to venting through the top exhaust. It defeated the point of side mounting vs top mounting the rad. Switched AIO from pull to push which helped, creating both positive pressure in the case and redirecting the hot air through the top exhaust as anticipated.

I have since bought a riser for vertical GPU mounting and thermals are better once again - I think the GPU was acting more like an air blocker than anything else while horizontal.

Like I say - only configured this weekend and GPU riser only installed last night. The last tweak I'm going to test is converting 2 bottom fans to pull, to see whether pulling the hot air from the blower through the botom of the case helps to dissipate the hot air better So, fan nearest the mounting brackets will push into the case, hopefully feeding the GPU fans with cool air, while the two towards the front are directly under the main blower vents.

Will report back with findings.

Is it possible to have a 360mm radiator AND fans in the rear of the side or would the fans/radiator have to be on either side?
