Lian Li LANCOOL III Reviews

Great Airflow

By Marcos
Rated 5 out of 5
Date: 2025-03-17

Got this case for new a build which will house a new 5090 GPU and 9800X3RD CPU that will need extra cooling. The front and back panels both conveniently open for easy access to replace components and it even have has small panels on both sides in the bottom for easy access to PSU and cables. It is a bit bigger than most ATX cases which gives ample space and allows great airflow. Mesh in the front and top for fans and AIO fans.

Great case!  Very well designed.

This is a very well-engineered case and I'm very happy with it. The two side panels are nice sturdy sheets of glass which swing open nicely on a hinge and close with a magnet. All the panels on the case open and close with magnets making it so much easier to get to things quickly. You can build a PC in here with almost no cables visible because the cable management in the back is so well done. I definitely recommend this case. Good stuff.

The controller included with the Lian Li LANCOOL III RGB Tower PC Case (White) BH #LILANCOOL3RW is for the included fans. You can use the software that comes with the UNI fans to control them.
