New Case Advice - Lian Li O-11 Air

ICEx21 · 29 Aug 2021 at 22:19

Hi all,

Due to overheating issues and unable to top mount the AIO I want, I've decided to buy a new case. The Lian Li O-11 seems to be the one that fits the profile for my needs but I just have a few questions if anyone can help.

1) I have the 3080ti and I'll also be using a sound card which is installed on the last pci slot in my motherboard (Asus Maximus Code X). Would the sound card stop me from installing fans on the bottom of the case?

2) I know I can use 140mm fans on the radiator which will go on the top of the case, but can I use 140mm fans anywhere else? The reason I ask this is because I already have 4 140mm Noctua case fans so don't want these to go waste.

3) Has anyone found any replacement dust filters for this case? I notice the reviews say the dust filters that come with the case are terrible and impede the air flow.

Thanks in advance!

i dont know if you already got the case but i recently just got this case, it came with 2 120 fans, i know you can have a 360 rad on the top and both the 120 fans at the front aslong as your mobo case fan headers aint in stupid places like mine. as for the 140s you can only put 2x140s at the top, one thing i can suggest is to get a cable kit as i have the rtx 3070 and due to the gpu power cables i cant close the glass side case completely.
i havent found any dust filters replacemtns but if i do find some i will post a link on here if i im aloud.

As you're more likely to install the radiator on the top,it will interfere with the front fans. The regular O11 and O11 air doesn't have a lot of bottom clearance. The fans will help, but won't be as efficient as they could be if another 1cm of clearance was available to allow more air in.
If the rad on the top restricts your front fans (may be an issue with triple 120mm fans) dual 140mm should be fine.
Also, the first and more important thing to do is remove the front filter. That filter is the more restrictive filter I've ever used.
