Today we’re taking a look at the Lian Li Lancool 217 INF, an airflow-focused mid-tower that builds on the original Lancool 217. Leo spent some time with the standard model earlier this year, and this new version keeps the same core layout and cooling philosophy but adds a striking infinity mirror front panel that instantly changes the look of the system. We’ll be going over the design, the build experience, and the thermal performance to see how well this updated configuration holds up, and whether the visual upgrade brings anything practical along with it.

Thermal Performance Testing
To simulate thermal demand we run the Cinebench R23 multi-thread benchmark and 3DMark Speed Way stress test simultaneously in a loop for 30 minutes to load the system fully. This gives the CPU and GPU enough time to reach constant steady-state temperature. With this data, we can compare how the system handles the thermal demand and measure peak noise levels.
Thermal performance is measured with the case in various configurations, such as the default, with the tempered glass left-hand side panel removed and with the front panel removed to see how these configurations affect the CPU and GPU temperature. During testing, only stock case fans are used unless otherwise specified. All water pumps are set to maximum RPM and fans are set to a custom RPM curve by the Motherboard software/BIOS.
All temperature measurements are presented as Deltas – meaning the ambient temperature has been deducted from the CPU temperature giving us a Delta. Data shown in the charts represent the average component temperature over the length of the test as measured by HWiNFO and then the last 15 minutes of the data are calculated to get the average. The ambient temperature during thermal tests is between 19-20⁰C.
Test System Specification:
Thermal Performance Overview
We tested the case thermals with a 360mm AIO as the exhaust at the top and in several different configurations. The default configuration shown in the charts is with the 360mm AIO at the top, 2 x 170mm front intake fans, 1 x 140mm exhaust fan and with all panels installed.

In terms of thermals, the Lancool 217 INF delivers solid results straight out of the box. In the default configuration, the CPU recorded a steady-state temperature of 53°C over ambient, while the GPU sat at 49°C over ambient under load. Removing the glass side panel or swapping the front and top mesh out didn’t significantly alter these results, showing that the case’s airflow design is already very efficient as standard.
The only notable improvement came from adding bottom-mounted fans, which reduced GPU temperatures to 46°C over ambient and lowered CPU temperatures slightly to 52°C. This indicates that the extra intake helps the graphics card breathe more easily, improving airflow across the lower section of the case. Overall, the Lancool 217 INF maintains strong thermal performance, and with just a small tweak by bottom fans, it can cool high-end components even more effectively.
You can get a better sense of how the airflow changes when adding floor fans by looking at the smoke tests in the video.
With no bottom fans installed, the GPU still draws air in through the lower side vent, so there’s already a natural intake path. However, once the two bottom intake fans are added, you can clearly see that airflow towards the GPU becomes much more direct and faster. This extra push of air helps feed the graphics card more efficiently, which ties in neatly with the small drop in GPU temperature we saw during the thermal testing.
Noise Output

Noise performance from the Lancool 217 INF stayed very consistent across all configurations, with system idle noise sitting at around 37 dBA regardless of setup. Under load, most configurations peaked at 50 dBA, showing that removing panels or swapping materials didn’t noticeably alter the acoustic profile.
The only setup that made a difference was with additional bottom fans installed. This configuration not only lowered GPU temperatures slightly but also reduced load noise to 49 dBA, suggesting that the improved airflow helped the GPU maintain lower fan speeds. It’s a small but welcome gain in both thermal and acoustic efficiency.
Closing Thoughts
The Lian Li Lancool 217 INF builds on the strengths of the original model while adding a much more eye-catching front design. The infinity mirror panel paired with the two large 170mm fans gives the case a distinctive look, but the visual upgrade doesn’t come at the cost of performance. Airflow through the front mesh remains strong, and the case maintains the high level of cooling capability that the Lancool series is renowned for.
Thermal performance throughout testing was consistently good, with the default configuration handling both CPU and GPU loads without breaking a sweat. The only notable improvement came when adding bottom intake fans, which helped direct airflow more efficiently towards the graphics card. This lined up neatly with the slight reduction in GPU temperatures we recorded. It’s not essential, but adding bottom fans is a small, worthwhile tweak for high-end GPU setups.

Hardware support is another area where the 217 INF performs well. There’s plenty of room for larger components, including all motherboard types, big GPUs and top radiators, plus the interior layout makes it straightforward to build in. Cable management is tidy, the tool-free panels are easy to work with, and overall build quality feels as solid as you’d expect from Lian Li at this price point. Nothing about the redesign interferes with the usability of the chassis.
Taken as a whole, the Lancool 217 INF is a well-executed refresh of an already great chassis that retains all the positive features of the original while adding a more striking front aesthetic. If you’re after a mid-tower that delivers strong airflow, great thermals, and a clean and simple building experience, all wrapped in a unique-looking package, the Lian Li Lancool 217 INF is a very well-rounded option that’s easy to recommend, especially at this price point.
The Lian Li Lancool 217 INF is available to purchase now from Scan priced from £107.99 for the black version HERE and £112.99 HERE for the white version.
Pros:
- Great airflow and cooling.
- Excellent build quality and hardware support.
- Brilliant cable management.
Cons:
- The front infinity mirror panel shows up every fingerprint.
- Lack of front radiator installation is not good for custom cooling.
KitGuru Says: The Lancool 217 INF is a strong evolution of the original, with excellent airflow, great thermals, high-end hardware support, clean build experience and impressive build quality with a striking new look at a decent price.
