The best case fans for Lian Li O11 Dynamic EVO should support a balanced intake and exhaust layout while fitting the clean, display-focused character of this dual-chamber case. Fan placement matters as much as airflow, especially when radiators, filters, and glass panels are part of the build.

be quiet! Pure Wings 3 120mm PWM Fan
Size
120mm PWM
Product Group
Personal Computer
Built for builders who want strong cooling headroom without locking into a constantly high fan speed, the Pure Wings 3 uses PWM control to combine a high top-end speed with a low minimum RPM. Its 120mm format suits common case-fan positions, while the rifle bearing is a practical fit for a conventional air-cooling build. be quiet! promotes maximum airflow and extraordinary air pressure, suggesting it is aimed at both case ventilation and more restrictive mounting spots. Noise is described as silent, although the listing does not provide a measured noise rating or airflow figure.
Pros & Cons
Reasons to Buy
- 4-pin PWM connection supports motherboard-based fan control
- Combines high maximum-speed capability with a low minimum RPM
- Marketed for both strong airflow and air-pressure performance
- Uses a rifle bearing
- Common 120mm case-fan format

Noise Level
Not specified
For builders who want a Lian Li 120mm case fan with a fluid dynamic bearing, the UNI Fan SL Infinity is a straightforward option in black. The listing identifies it as a single 120mm fan and confirms the bearing type, a design commonly associated with smoother long-term operation than basic sleeve bearings. Airflow and noise figures are not provided here, so it is difficult to compare its cooling output or acoustic performance against alternatives on paper. It makes the most sense for a build where the SL Infinity model and black finish are the priorities.
Pros & Cons
Reasons to Buy
- Confirmed 120mm case-fan size
- Fluid dynamic bearing is explicitly listed
- Black color offers an understated build-friendly look
- Clear Lian Li UNI Fan SL Infinity model identification

Which Fans Suit an O11 Dynamic EVO Build
I would focus on 120mm PWM fans first, since they give you the flexibility to fill the O11 Dynamic EVO’s side, bottom, top, and rear mounts while letting the motherboard adjust speed with temperature. If your build also uses liquid cooling, our best 360mm AIO liquid CPU coolers guide can help match the radiator plan to your fan layout.
- For a polished RGB showcase build, I would go with the Lian Li SL Infinity. Its infinity mirror design and fluid dynamic bearing make it a natural visual match for a glass-panel case, while its 120mm format keeps placement straightforward.
- For strong airflow with simpler multi-fan wiring, I would point to the Thermalright TL-M12Q-S X3. It uses PWM control, ARGB lighting, and daisy-chain connections, so a larger fan array can look cleaner inside the case.
- For a no-RGB setup that prioritizes radiator or filtered-intake duty, I would choose the ARCTIC P12. Its pressure-optimized design is suited to airflow resistance, and the multi-pack makes it practical for populating several mounts.

FAQs
Q: What fan size fits the Lian Li O11 Dynamic EVO?
A: A 120mm fan is the common choice for this case layout and works well for building coordinated intake and exhaust zones. It is also the standard size used by the case fans below, which makes it easier to plan around radiators and available motherboard headers.
Q: Should I use PWM fans in an O11 Dynamic EVO?
A: PWM fans are usually the better choice because their speed can respond to system temperature through a compatible four-pin header. This lets a system stay calmer at light loads and increase airflow during gaming or demanding work without leaving every fan at full speed.
Q: Are high-static-pressure fans useful for bottom intake?
A: They can be useful when air has to pass through a dust filter, radiator, or other restriction. Pressure-oriented fans are also a sensible option for radiator positions. For more cooling layout ideas, see our 120mm fan guide for CPU coolers.
Q: How should I arrange intake and exhaust fans?
A: A sensible starting point is bottom and side intake with top and rear exhaust, then adjust for the radiator location. The goal is to feed cool air toward the graphics card and CPU area while giving warm air a clear path out of the enclosure.
Editor’s Verdict
For the best case fans for Lian Li O11 Dynamic EVO, I would choose the Lian Li SL Infinity for a coordinated RGB display build. Builders who want to populate several positions with cleaner wiring should instead consider the Thermalright TL-M12Q-S X3.
