Best Fans for the Lancool 216 (2026): 5 Picks by Mount

The Lancool 216 ships with two 160mm fans at the front, and that is the end of the front conversation. Nobody makes a 160mm aftermarket case fan, so the largest intake surface in this case is whatever Lian Li put there on day one. What is left to decide is a top bracket, a PSU shroud, a PCIe slot bracket and one rear mount.

The case advertises room for ten fans. Most 216 builds are better off at four. Here is every mount, what it takes, and whether filling it is worth your money.

Our top pick: ARCTIC P14 PWM PST A-RGB 3-Pack

The top bracket is the only empty mount on this case that reliably pays you back, it takes 140mm fans, and three of them cover the bracket with one left for the rear slot.

What the Lancool 216 gives you to work with

Radiator support runs to 360, 280 and 240mm at both the front and the top, with 240mm at the bottom. The motherboard tray is height adjustable, and dropping it into the water-cooling position opens a 63mm gap under the top panel. If a radiator is in your plan, work out whether a 360mm radiator fits before you buy fans, because a front radiator means the stock 160mm pair comes out.

One number to watch on the air-cooling side: the case lists 180.5mm of CPU cooler clearance, measured without a top fan row competing for the space. Tower coolers around 154mm fit clean. Anything near 168mm gets tight once the side panel is back on. The numbers that decide fit are in our cooler clearance guide.

The mounts that are not worth populating

The PSU shroud is the one that costs people the most money. Owners who have tested this exact case with and without shroud fans report roughly no change in GPU temperature at around 1450 RPM, and the most generous reports put the gain at one to two degrees. The front mesh already feeds the graphics card directly, so shroud fans are pushing air into a space that was not short of it.

The top bracket has its own trap. Configuration threads on the 216 suggest that a fan in the front-most top position pulls most of its air straight off the upper front intake fan and vents it out of the roof before it reaches the CPU cooler. Biasing the top toward the rear, or running two 140mm fans instead of three 120mm ones, keeps the front intake doing the job it was installed for.

The PCIe slot bracket does something, but only in one situation: a short graphics card with a blower or single-fan cooler sitting in dead air low in the case. A modern triple-fan card already sits in the front intake path.

None of this applies once liquid cooling enters the picture. A radiator changes the pressure map completely, and at that point the fan plan is a radiator fan plan. Our 240mm AIO picks cover that path.

How we picked

Count first. The question for this case is not which fan is best in the abstract, it is how many fans the chassis can use before the returns stop. That number is two, at the top, with a third available for the rear if you want a quieter one than the factory unit. Every pick below is sized to that answer rather than to the case's ten-mount maximum.

Size second. Where a mount takes both, 140mm beats 120mm: a larger blade moves the same air at a lower speed, and the 216's open top panel muffles nothing. The 120mm picks are here for buyers who want three lit fans across the bracket, or who are heading toward a front radiator.

Brand third, and only against evidence. Every fan here appears on independent fan test charts rather than only on retailer listings, which rules out the cheap lighting-first units that never publish a static pressure figure. The wider shortlist we draw from lives in our PC fan roundup.

Header budget counts as a spec. A mid-range board has two chassis headers once the CPU cooler takes one, so a three-fan top row either shares PWM signal or needs a fan hub. Two of the picks solve that in the box. Two of them do not, and we say so in their sections.

What it does well

A 140mm blade moves the same air as a 120mm at a lower speed, and the 216's top bracket takes two of them. That is the whole argument for going 140 here. Lower RPM for the same exhaust means the case stays quiet under load, not only at idle.

PWM sharing is the part that makes this a three-fan purchase rather than a three-header problem. Chain the fans together, plug one lead into the chassis header, and the motherboard drives all three off a single curve. On a board with two chassis headers and a CPU cooler already occupying one, that matters more than it sounds.

The A-RGB versions of the 216 ship with lit 160mm fans at the front. These match that without adding a second piece of lighting software to the build.

What you give up

You are buying three fans for a two-fan mount. The third unit has one honest home, which is the rear slot, and the rear slot already has a competent 140mm PWM fan in it from the factory. Plenty of owners end up with a spare in a drawer.

A-RGB also means a second cable per fan, so the clean single-header story gets a little less clean once the lighting leads join in. And at matched speed this is not the quietest 140mm made. It is the one with the best ratio of air moved to money spent.

Who it's for

The default 216 owner. You want the top bracket handled correctly in one order, you already have the ARGB front, and you do not want to think about fan headers again.

What it does well

This is the price-per-fan benchmark for the category, and has been for years. Five pressure-optimised 120mm fans cost about what two premium 140mm units do. If you are filling more than one case, or a front radiator is already in the plan, this pack covers both.

The blade profile is built for restricted mounts, which suits the 216's top bracket once the motherboard tray sits in its air-cooling position and the gap tightens up. Same PWM sharing as the 140mm version, so the whole top row still lands on one header.

What you give up

No lighting at all. On a 216 with the ARGB front fans that is a visible mismatch, and the top bracket sits directly in your eyeline on a desk.

Three 120mm fans at the top also need more speed than two 140mm fans to shift the same air, so the noise floor is higher for the same result. And a five-pack tempts you into filling mounts that do not pay. Buy it for the price per fan, not the count.

Who it's for

Builders with more than one machine to populate, and 216 owners who are heading toward a front radiator and will need 120mm units anyway.

Specs

What it does well

The 216 is a mesh case with an open top panel, which is exactly why it cools well and exactly why it leaks noise. Exhaust fans on this chassis sit under a vent with nothing between them and your ears. That is the narrow case where paying up for a quiet fan changes something you can hear.

The bearing is the quiet part, but the mounting corners are the part people underestimate. A top bracket is a large flat steel panel, and a fan bolted rigidly to one turns it into a speaker. The decoupled corners stop the panel picking up motor hum at the speeds a top exhaust runs at.

What you give up

One fan per box. Covering the 216's top bracket costs more than a three-pack of the Best Overall, and you still have nothing left for the rear.

There is no lighting, which rules it out of a showcase build. More importantly, the premium here buys noise and nothing else. If you game in a headset, the case could be twice as loud and you would not know. Most buyers have never tested whether they had a noise problem before paying to solve one.

Who it's for

Anyone who named quiet operation as a hard requirement: the machine lives on the desk, you work beside it, and the GPU is already the loudest thing you are willing to tolerate.

Specs

What it does well

Three lit 120mm fans for less than a single premium 140mm. Thermalright's budget line is the one that keeps turning up on independent test charts rather than only on retailer pages, and that is the bar worth holding at this price.

The bearing is an S-FDB rather than the plain sleeve bearing that usually shows up here, which is the difference between a fan that is still quiet in year three and one that starts ticking in month eight. A 1550 RPM ceiling is plenty for an open top bracket with no radiator behind it.

What you give up

No PWM sharing. Three fans mean three leads, and a mid-range board usually has two chassis headers once the CPU cooler has taken one. Budget for a splitter or a hub in the same order.

The ARGB will sit next to Lian Li's own front fans and not quite match them, since the two run on different controllers with different colour calibration. Static pressure is also thin, so these are a poor choice if a radiator ever goes in that bracket.

Who it's for

A first build on a real budget that wants the top bracket populated and lit without pulling money out of the GPU line.

Specs

What it does well

Same house as the case, and it shows. The frames interlock, so a three-fan top row becomes one cable instead of six. In a case whose pitch is clean routing, that is worth something real.

The controller ships in the box rather than as a second purchase, which takes all three fans off the motherboard's header budget in one move. Lighting runs through the same software as the case's own front fans, so the front and the top finally agree with each other.

What you give up

The highest price per fan here by a wide margin, and the worst airflow per unit of spend. You are paying for the cable run and the lighting, not for the air.

The controller wants a SATA power lead and an internal USB 2.0 header, and USB 2.0 headers are contested on smaller boards. The proprietary connector also means these fans are awkward to carry into a non-Lian-Li case in a future build.

Who it's for

The owner building a showcase 216 who already runs Lian Li lighting and wants the top bracket to match the front without adding a second ecosystem to the machine.

Bottom line

If you own a 216 and want this settled in one order, buy the ARCTIC P14 PWM PST A-RGB 3-Pack and put two at the top. If you have several cases to fill or a front radiator coming, the ARCTIC P12 PWM PST 5-Pack is the cheaper path. If the machine lives on your desk and quiet is a hard requirement, pay up for the be quiet! Silent Wings 4 140mm. If the budget is genuinely tight, the Thermalright TL-C12C-S X3 fills the bracket for very little. And if the build is a showcase, the Lian Li UNI Fan SL-Infinity 120 3-Pack is the one that matches the case. Whatever you pick, stop at the top bracket. The Lancool 207 and the rest of our budget airflow case picks follow the same rule.
