Quick Answer
Yes, the RTX 5070 Ti Eagle fits the Lian Li O11 Dynamic, but check length and side-glass clearance: the O11/Y60 families take cards up to roughly 410mm, and the RTX 5070 Ti Eagle sits around 330-360mm, so it clears comfortably with room for cabling.
RTX 5070 Ti Eagle clearance in the Lian Li O11 Dynamic
The RTX 5070 Ti Eagle is a triple-fan card around 330-360mm long, 140mm tall and 60-75mm thick. The Lian Li O11 Dynamic accepts GPUs to about 410mm, so length is never the problem; the real checks are vertical/horizontal mounting style, the side-glass gap on the Hyte Y60's chambered layout, and clearance for the 12VHPWR power connector at the top. Leave 35-40mm above the card for the cable bend radius so it does not press against the glass; on the Y60 the GPU mounts vertically, so confirm your riser supports PCIe 5.0 if you want full bandwidth.
Build tips for a clean fit
Plan airflow around the card: in an O11 Dynamic run three intake fans on the side and exhaust up and rear; the RTX 5070 Ti Eagle pushes 350-575W of heat depending on the model, so case fans matter. For the Y60's vertical mount, the glass-to-GPU gap is tight (around 40mm), so a thicker card can choke its own intake; pick a model with a flow-through cooler and keep the bottom panel clear. Cable-manage the 12VHPWR fully seated to avoid the connector issues that plagued early high-wattage cards.
measure your RTX 5070 Ti Eagle GPU's exact length on the spec sheet and add 20mm for cable clearance; the Lian Li O11 Dynamic and Y60 both take long cards but the vertical-mount glass gap is the real constraint.
FAQ
Does the RTX 5070 Ti Eagle fit in the Lian Li O11 Dynamic?
Yes. At roughly 330-360mm it clears the case's ~410mm GPU limit easily. The main thing to verify is the side-glass gap and power-connector cable bend, especially on vertical mounts.
Do I need a riser cable?
Only for vertical mounting (standard on the Hyte Y60). Use a PCIe 5.0-rated riser so a current-gen card runs at full bandwidth; horizontal mounts need no riser.
Will airflow be enough for this card?
Yes if you set up intake fans properly. Run side or bottom intake and top/rear exhaust, and keep at least 40mm clearance around the GPU intake so it can breathe.
