Cooler Master has expanded its product line in recent years to include peripherals for all stripes. gaming chair When monitorBut the company doesn’t offer coolers like the classic Hyper 212 EVO or HAF700.
And the company keeps an eye on its core competencies. The Cooler Master MasterLiquid PL240 Flux is his 240mm AIO in midsize with lots of RGB. Can it handle Alder Lake’s increased heat density while justifying its rather high asking price of $189.99?

Package includes:
- 240mm radiator + CPU block
- Two 120mm PL-FLUX fans
- Mounts for all modern CPU sockets including LGA1700, TR4, AM4/AM5
- fan splitter
- thermal paste
- user manual
- USB controlled ARGB hub
- ARGB splitter cable
Installation of cooler
Installing the Master Liquid PL240 FLUX was a breeze. First, secure the backplate to the motherboard using standoffs. After applying thermal paste, press the CPU block onto the standoffs and secure with the included screws.

What is the difference from other coolers?
- Premium dual chamber pump
According to Cooler Master, their latest dual-chamber pump is driven by a high-speed motor utilizing a ceramic bearing impeller, enabling increased flow in a small package with low noise levels.
Cooler Master’s reduced radiator profile (27.2mm) means it fits better in cases where there isn’t much space.
- Cooler Master PL-FLUX Fan
It’s not just radiators and pumps. Fans have a significant impact on cooling performance and noise levels. The PL260 Flux includes Cooler Master’s PL Flux fan with his ARGB lighting that shines through the blades. You can’t buy these fans individually (at least not yet).
| model | PL flux |
| size | 120mm |
| fan rotation speed | Up to 2300 RPM +- 10% |
| air flow | 72.37 CFM (100% speed) |
| air pressure | 2.96 mm H2O (Velocity 100%) |
| noise level | Up to 32 dB(A) |
| lighting | ARGB |
- USB ARGB controller with software support
Cooler Master includes a USB powered ARGB controller box. This is useful if your motherboard doesn’t have a spare ARGB header or you don’t want to use your motherboard’s software to control the lights. If the 3 ports included in the box are not enough for your lighting needs, Cooler Master also includes a splitter that allows you to connect 5 additional devices, and the splitter can be used in combination with ARGB for up to 7 different devices can be controlled. controller.
Although you can use the cooler without the cooler, Cooler Master offers Master Plus+ software that allows you to control devices connected to the USB ARGB controller and other supported peripherals.

Testing Master Liquid PL240 Flux on Intel’s Cor i9-12900K. Due to the increased heat density of the Intel 7 manufacturing process and changes to core and component layouts, Alder Lake CPUs are more difficult to cool than their predecessors in the most demanding heat-loaded workloads.
This means coolers that kept previous generations like the i9-10900K nice and cool struggle to keep Intel’s i9-12900K below TJ max (the maximum temperature before the CPU starts throttling) It means that there are cases. Many coolers I’ve tested can’t keep the i9-12900K below TJ max when power capping is lifted for workloads like Cinebench and OCCT.
Keep in mind that there are many factors that can affect cooling performance. Your system’s motherboard can affect this, as there are boards on the market with CPU sockets that do not conform to Intel’s specifications, causing warping and poor contact with the CPU, affecting thermal performance. The case used also affects the cooling effect.

test method
To test the limits of a cooler’s ability to dissipate heat, we run two major stress tests. cine bench When OCCT, for 10 minutes each. This may be a short amount of time, but it’s enough to push most coolers (both air and liquid) to their limits.
While stress testing in Cinebench, I ran with the power cap removed and a 200W CPU power cap applied. In this test setup with MSI’s z690 A Pro DDR4 motherboard and Be Quiet’s Silent Base 802 computer case, only the best coolers can pass the Cinebench test when the power cap is lifted.
Do not test OCCT without power capping. Because when I try this, the power consumption of the CPU package exceeds 270W, instantly throttling even the best of his AIO coolers. Instead, we test at 200W to give the cooler a chance of passing. We also include the 140W results to provide closer data for lower-end CPUs such as AMD’s Ryzen 5600x and Intel’s i5-12400.
With Alder Lake’s cooling demands in mind, we evaluate CPU coolers in three different tiers.
Tier 1: These coolers are able to keep the i9-12900K below TJ max at most loads without enforcing power limits. I believe only the best liquid coolers meet this criteria.
Tier 2: These coolers can apply a CPU power limit of 200W to keep the i9-12900K below the TJ max threshold. I believe most liquid and air coolers meet this criteria.
Tier 3: These coolers are able to keep the i9-12900K below TJ max with a CPU power limit of 140W applied.
