Will a 360mm AIO Fit in a Lian Li Lancool 216? (2026)

Yes. A 360mm radiator fits the Lian Li Lancool 216 at the front and at the top. Lian Li lists 360, 280 and 240mm support in both positions. The number that actually decides your build is the one that radiator-support line leaves out: radiator thickness.

The top rail clears 63mm of radiator plus fans, but only with the motherboard dropped into the case's lower water-cooling position. Leave the board where it ships and you have under 55mm. A 27mm radiator clears either way. A 38mm radiator lands exactly on 63mm and forces the lower mount. Measure the radiator before you decide where the board goes.

At a glance

Where each mount wins

The thickness gate, in numbers

A 120mm fan is 25mm thick. That single number turns Lian Li's clearance figures into a shopping rule. With the motherboard where it ships you have under 55mm at the top rail, which means a radiator up to roughly 30mm. Drop the board into the water-cooling position and you have 63mm, which means a radiator up to 38mm.

Three radiators, three answers. The Corsair iCUE Link Titan 360 RX runs a 27mm radiator, so the stack is 52mm and it clears in either configuration. The Arctic Liquid Freezer III Pro 360 runs 38mm, so the stack is exactly 63mm and the board has to come down. Anything at 45mm or thicker never goes up top at all.

The front is the escape hatch, and here it costs less than you might expect. Graphics card length is not the constraint. The 216 clears 392mm of card, and a front radiator sits ahead of the card rather than across it. What it costs is the pair of 160mm PWM intakes the case ships with. Those two fans are why this case is our top pick for high-end GPU builds, and a front radiator means pulling both and running three 120mm fans instead. Less intake area, and what is left reaches the graphics card already carrying CPU heat.

If you are still deciding between sizes rather than mounts, the 240mm versus 360mm question is the one to answer first. And if the case itself is still open for debate, a Fractal Design North runs the opposite trade: its top caps at 240mm, so a 360 has to go up front and it eats card length doing it.

What it does well

27mm of radiator plus 25mm fans is 52mm, and the top rail wants under 55mm in the position the case ships in. That is the whole pitch. You install it where the motherboard already sits and never open the manual to the water-cooling section.

The iCUE Link cabling matters more here than elsewhere. The 216's top bracket lifts out, so you build radiator and fans on the bench and drop the assembly back in. One cable instead of six is the difference between a twenty minute job and an afternoon. For the wider field at this size, our 360mm AIO roundup covers it.

What you give up

27mm is the least fin stack on this list. On a 9950X or a 285K running sustained all-core work you will hear the fans find the top of their range, and a thicker radiator would not have to.

iCUE Link is also a commitment. The 216 ships with Lian Li's own 160mm fans on the front, and running Corsair's hub alongside them leaves you with two pieces of software and two fan curves that know nothing about each other.

Who it's for

The default Lancool 216 build. A mainstream AM5 or LGA1851 chip, and a builder who wants the radiator in the roof and the case closed the same evening.

What it does well

398 by 120 by 38mm is roughly a centimetre more radiator than the class standard, and Arctic packed extra fin surface into that depth. On a chip that genuinely pulls sustained wattage, the headroom gives heat somewhere to go instead of pushing it into the fan curve.

The small fan on the pump head is the underrated part here. A top-mounted radiator means the front 160mm fans push air across the graphics card rather than the socket, so the VRM area loses its dedicated airflow. A fan sitting right there covers that. Arctic backs the unit with a six year warranty, unusual in a category where the pump is the part that fails.

What you give up

38mm plus 25mm fans is 63mm, and 63mm is the entire top gap. There is no margin, and the margin only exists at all with the motherboard in its lower position. If the system is already built in the standard position, fitting this means stripping the board out to gain 8mm.

It is not quiet at the top of its range either. The fans reach 3000 RPM and they sound like it. If the top mount is off the table, the honest move is a 280 instead rather than forcing a thick 360 into the front and giving up both 160mm intakes for it.

Who it's for

A 9950X, 9950X3D, 14900K or 285K-class chip that really does pull sustained wattage, in a build that has not gone together yet so the lower mount costs nothing.

Specs

What it does well

27mm of radiator puts this back in the fits-anywhere bucket, so the clearance question is settled before you start. What you are paying for is everything after that.

The SL-INF fans daisy-chain into the same Lian Li controller the case's front 160mm fans already run on, so the build ends up with one lighting system instead of two fighting over the same glass panel. Underneath the pump head is an Asetek design, so the mechanically important part is a known quantity.

What you give up

It is the expensive way to solve a 52mm clearance problem. Thermally this is a 27mm radiator like any other 27mm radiator, and the pump head styling is what the extra money buys.

Watch the SKU. Reports put the base Galahad II Trinity at 39mm and the Performance version at 32mm, which lands both of them on the wrong side of the 55mm gate. The SL-INF is the 27mm one, and the product line name alone will not tell you which listing you are looking at.

Who it's for

The showcase 216 build. You already run Lian Li fans, you want one lighting ecosystem, and you are not chasing the last few degrees.

What it does well

Here the air cooler is the option that costs nothing. The Phantom Spirit stands 154mm against a published ceiling of 180.5mm, and the real ceiling is tighter: with the side panel on and ARGB tops on the fans, usable height is closer to 165mm. An NH-D15 G2 at 168mm is already too tall. This one fits clean, the front stays empty so both 160mm intakes keep working, and the top stays open so hot air keeps leaving.

I reversed on AIOs a few years back and this cooler is most of the reason. Dual tower, seven heat pipes, two 120mm fans, and it trades blows with 240mm units and thin 360s on any mainstream chip. There is no pump to fail in year four and dump warm coolant onto the graphics card sitting underneath it.

What you give up

It is a large block of metal in a case with a glass side panel. If the reason you wanted a 360 was to look at one, this is not that.

It also runs out of road before the 250W-plus parts do. On a 9950X under sustained all-core load a thick 360 is genuinely the better tool. A 240 on the top rail is the middle option when the tower is too much metal but a 360 is too much radiator.

Who it's for

The builder who wanted the 360 for temperatures rather than for the view, on a chip under roughly 200W sustained.

Bottom line

Radiator thickness is the whole answer here. If you want the 360 in the roof without moving the motherboard, buy the Corsair iCUE Link Titan 360 RX RGB. If the chip pulls 250W or more and the build is still on the bench, drop the board and buy the Arctic Liquid Freezer III Pro 360 A-RGB. If you already run Lian Li fans and want one lighting system, buy the Galahad II Trinity SL-INF 360 and check the SKU before you order.

If the chip is mainstream and the glass panel is not the point, buy the Phantom Spirit 120 SE and keep both 160mm intakes. Whichever way you go, the wider cooler and case framework is worth reading before you commit.
