The Glacer 240L is the result of a collaboration between Cooler Master and Swiftech. It's pre-filled and ready to go out of the box, but unlike many other similar CPU coolers it can also be expanded to add more radiators, GPU blocks, or other cool hardware!

The Cooler Master Glacer 240L is introduced as a collaborative effort with Swifttech, emphasizing its status as a pre-filled liquid CPU cooler with notable expandability. The unboxing segment highlights eco-friendly packaging, a fully assembled unit, and a robust mounting kit that includes steel brackets and Swifttech hardware designed to ensure correct clamping force per CPU socket specifications. The radiator and fan assembly is showcased next, including a fill port that can be kept closed if expansion or coolant changes are not planned, and Cooler Master’s blade master fans, chosen for static pressure on a fat radiator. Attention is drawn to the radiators’ full copper brass construction, which is positioned as delivering superior performance relative to surface area compared with aluminum variants, while also noting the longer tank design required to accommodate the reservoir and fill port. The guide explains the mounting hardware, rotatable 38-inch elbow fittings, and removable clamps that facilitate tubing swaps, underscoring the system’s modular and upgradeable nature. The CPU block integrates a Swifttech microfin water block with a copper base, capped for a polished look, and pre-installed backplate mounting for easy installation across Intel sockets. In the testing setup, the reviewer demonstrates the system with an overclocked 3930K and a GTX 580, then repeats tests with a standard Noctua NF12 to establish a consistent baseline, emphasizing performance consistency whether stock or with aftermarket fans. It is observed that the stock pump speed yields solid performance comparable to the H220, while the higher pump RPM is noted to be louder, prompting a suggestion to reduce the speed when multiple GPUs are involved. The segment concludes by comparing user needs for all-in-one solutions versus expandable kits, inviting viewers to consider whether they prefer a ready-to-use unit or a scalable platform that can evolve with their cooling ambitions, such as adding GPUs or extra radiators in the future.

Questions answered

What makes the Glacer 240L expandable beyond a standard all-in-one cooler?
It features a modular design with a longer reservoir, rotatable fittings, removable clamps, and compatibility to add more radiators or a graphics card water block later.
How does the pump speed affect performance and noise in the Glacer 240L?
A higher pump RPM improves cooling performance but increases noise, so users may dial it down if noise is a concern or if extra GPUs are added.
