creating a silent aircooled Lian Li O11 Dynamic XL

[Mr Carrot]

Hi guys considering my next build for the Q4 CPU releases and am looking to bin my current case and move to an XL, I am particularly taken with the front glass and hidden PSU, and hidden hot-swapping drives for 4 8tb ssds so I think I am locked into this case at this point.

Now I also have an aversion to AIO coolers - after an intensely annoying experience with Swiftech which led me back onto aircooling and i've had a dark rock pro 4 for a few years which has been incredibly silent and looking to reuse that.

Now obviously aircooling in a liquid cooling focussed case is a bit of an issue so wondering would this work:

3 side mounted 120mm silent wings 3 pwm - mounted into a pwm fan splitter into the mobo

3 bottom mounted 120 mm silent wings 3 pwm - mounted into a pwm fan splitter into the mobo

1 rear mounted 120mm silent wings 3 pwm right into mobo

(I have 4 of these fans already)

Now is this potentially too many fans? Would putting 140mm in the bottom be better than three 120s for creating the correct pressure gradient? Should I put some on the top too?

Not too worried about cost just looking for it to be silent.

Graphics card is a 3090 suprim.



Or am I making a mistake on this case for air? There's an alternative in the 7000d airflow but aesthetically it's a plastic mess vs the metal and glass of the lian li.

- I like the asthetic of the hidden psu, the storage behind the mobo for HDD cages (I have 4 hdd and three SSD) etc. - the suprim is a BIG card too. I have a large space for the case to fill as part of the room aesthtic up against a lot of chunky electronic and furniture so a small case will look a bit...twee.

Currently have an antec p380 there - love the machined aluminium look but it's struggling in terms of airflow and cable management, window size etc. is very dated.

3 exhaust on top makes some sense but wouldn't it be drawing up hot air into the intake fans for the CPU cooler?

Thanks for the feedback guys - it looks like I am wed to an XL to fit in a dark rock pro 4 (or equiv) giant air cooler.

Unless Lian Li are going to release a revision of the case with better mesh in the next few months (which would be nice) It looks like I am going to go with

6* 120mm intake bottom and side. 4* 120mm exhaust (rear and top).
