Lian Li’s P28 UNI fans have been designed to offer uncompromising performance, with exceptional airflow and static pressure. The P28 fan has a maximum speed of 2600RPM, at which they can produce 92CFM of airflow, with a static pressure of 4.79mmH2O. What's more, these fans have been optimised for restricted airflow such as when mounted on a radiator. As such, they remain whisper quiet even when operating at maximum speeds, reaching just 32.1dB(A). To accomplish this outstanding performance, Lian Li has made several innovations in the construction of the P28 UNI fan. This includes utilising liquid-crystal polymer (LCP) for the fan blades, and improvements to the motor design. Furthermore, Lian Li’s P28 fans are ideal for those who want high-performance fans without any RGB lighting. With that said, it is possible to add lighting to these fans with an optional lighting kit (sold separately).
Lian Li’s P28 UNI fans have been designed to deliver outstanding cooling performance. To achieve this several innovations have been incorporated into the P28, such as making these fans slightly thicker than standard. The P28 UNI fan is 28mm deep which is 3mm larger than many fans, this extra size allows for increased airflow and static pressure. In addition to the extra depth, the P28 UNI fans also utilise LCP for the fan blades. LCP is a strong material, which reduces vibrations in the blades, allowing the fan impeller to be widened, reaching just 0.6mm away from the frame.
In addition to the refinements to fan size, the motor of these fans has seen several updates. This includes securing the impeller to the shaft through an all-metal bearing shell. Additionally, the shaft of the motor is reinforced with copper shielding. What’s more, to keep the impeller stable, a magnetic ring is seated within the bearing shell, and more magnets are also incorporated within the frame of the fan. Through the interaction of these two sets of magnets, the fan is held stable. With all these innovations combined, the P28 produces minimal noise, even when operating at high speeds.
The P28 UNI fan features Lian Li’s innovative daisy chain design, where you can connect multiple fans to a fan header with a single cable. To achieve this result, the frame of the fans features both contact pins and a contact pad. A further fan can be added to this for control of three fans with a single cable. What’s more, a second cluster can be daisy chained from this first one for a total of six fans controlled from a single header. Furthermore, the interlocking key locks are easily removed, letting you use a set of P28 UNI fans effortlessly with radiators.
Something you may notice that distinguishes the Lian Li P28 UNI fans from many of their contemporaries is that they don’t feature any RGB lighting. This makes them ideal for the enthusiast who wants to build a high-performance gaming PC, without any RGB. However, if you do want to add lighting to these outstanding fans, you can by simply removing one of the aluminium side strips and replacing it with an ARGB lighting (sold separately).

decided to pick up one of these P28 fans for my o11 Dymanic Evo case as a rear exhaust fan. got to say the build quality of these P28 fans are top tier. I've got this fan as a rear exhaust and set to 1200rmp when gaming and even at this speed it's extremely quiet. definitely picking up a triple pack of these fans soon to replace my current intake fans. would highly recommend these fans, for a premium fan they deliver great performance for the price you pay.
Got 4 of this for my old build to replace noctua's industrial 2000rpm while doing PC maintenance and decided to change fans as well. Now my old 4930K is doing ~4.8ghz at 1.52v under 80 degrees. Fans at 2600rpm are very close to noctuas when it comes to noise but far better in performance, not saying that noctuas are bad, just saying P28 are overkill. One mistake I've made was buying 4 of them all separated. I should buy a tri pack + one separated, the tri pack comes with a fan controller, luckily I had one at home anyway. Also daisy chain them fans is simply brilliant, 4 fans connected only one cable.
