Please help with matching up USB ports on mb to USB ports on case

[Yoshiii335]

Hello,

I have a Lian Li Lancool 3 case.

The front of the case has three USB ports. One USB-C 3.2(from the manual but website says 3.1) and two 3.0 Type A ports. I have a Asus ROG Strix Gaming B650E-E mb with one USB 3.2 Gen 2 Connector(Supports USB Type-C), 1 USB 3.2.1 header supports additional 2 USB 3.2 Gen 1 ports, 2 USB headers support additional 4 USB 2.0 ports.

Can I use any of the connections on the front case? What ports on the case do I connect the ports on the mb?

Look at the connectors on the cables from the PC case then find the corresponding connectors on the motherboard. They have different plugs so you can't mistakenly plug in the USB-C plug into a Gen 1 motherboard connector that doesn't support it.

They should look like this

Consult your product manuals if necessary. The one on the left is for the newer Gen 2 (USB-C) port.

Legacy USB 2.0 headers have nine pins like this:

A newer case like the Lancool III probably doesn't have legacy USB 2.0 ports on the front panel (my Lancool II Mesh does not). Those four connectors on your motherboard are for legacy cases and/or internal peripherals.

All three connectors are keyed so you can only plug them in one way with the matching cable.

Best of luck.

asking to make sure ports line up, so the USB C 3.2 port on the case will connect to the USB 3.2 Gen 2 Connector on the mother board ?, so will I only get the 3.2 gen 1 speed on the case or since I am connecting a Gen 2 USB C 3.2 head to the connector on the case, I will get Gen 2.2 speeds? Would I connect the USB 3.2 Type A Gen 1 connector on the mb to the USB 3.0 port on the case? Thanks

I'd just plug in matching connectors and see what happens. Nothing will explode.

If you end up dissatisfied, send them back and buy something else.

(Disclaimer: I am using an ASUS ROG Strix B550-E motherboard in a Lian-Li Lancool II Mesh Performance. I purchased the optional USB 3.2 Gen 2 port for the case's front panel.)

Front USB (Total 7 ports)
1 x USB 3.2 Gen 2 connector (supports USB Type-C®) hook your front panel usb-c to that port

1 x USB 3.2 Gen 1 header supports additional 2 USB 3.2 Gen 1 ports


Hook your front panel usb A ports to that

Did you get the port from LIAN LI?

I have the Lancool 3, I find that the AIO 360 radiator and fan I have covers up the top of the motherboard some. Does it do the same on yours?

Yes, and irritatingly overpriced too. But it fit perfectly and works. I was annoyed that they were too cheap to include it in the base configuration but I'm over it now.

Yes, I had a 240mm AIO radiator on top for a while, it did the same but did not affect thermal performance to any measurable effect. It's offset a bit which probably helps with airflow.

I'm using a 360mm AIO radiator on the front panel now, the top has two 140mm exhaust fans. Internal case temperature did not change at all. The case is well designed and provides adequate airflow.

One thing I like is the optional GPU bracket. I've never seen that as an option for other cases.

The Fractal Meshify 2 has a gpu bracket. That case is good but the AIO hangs down further than on the Lancool 3 and covers the top vrm heatsink completely and some of the ram. I like that case more but I read that mounting aio on the front would send warm air to the gpu and I have a 3090ti EVGA FTW3. It does have mounts for putting fans on the bottom of the case but not sure how well the air will reach up through the holes in the psu cover.

You figure out your ports or what?

I know nothing about the Fractal Meshify 2. The company has a good reputation, I'm confident they market some well designed cases.

The Arctic 360mm Liquid Freezer AIO in my Lancool II is cooling a Ryzen 5800X and exhausting inside the case (i.e. configured as an intake). My GPU in that build is an ASUS TUF Gaming GeForce RTX 3080 10GB. I am using the two fan mounts on the Lancool II's PSU shroud for extra interior airflow.

There seems to be adequate airflow for my particular build. I cannot speak for anyone else's configuration.

I have two other smaller cases with front mounted AIO radiators exhausting inside the case. Again with adequate ventilation, I don't see this as a problem.

I'm sure satisfactory thermal performance can be achieved with many cases not just these two.

Thank you
Will do it now that I understand how to do it.
